Captive Propagation of Shrimp

April Kirkendoll is a professional aquaculturist and marine aquarium
hobbyist who has worked with shrimp for over 20 years. In 1997, she
started Crunchy Critters, an aquaculture venture that specialized in
captive-raised invertebrates. She raised Peppermint shrimp in
commercial numbers and experimented with 2 related species of cleaner
shrimp and 2 species of reef lobsters. She is the author of 2 books:
How To Raise & Train Your Peppermint Shrimp and The End of Cancer:
Seeking A New Understanding To Defeat The Enemy Within.

April Kirkendoll 是一个养殖20多年虾的水产养殖专家和一个海水养殖爱好者。
在1997年，他开始他的水族冒险经历，专门致力于无脊椎动物的养育。她大量繁
育薄荷虾并进行与薄荷虾同类的两种清洁虾及2种龙虾的实验。她已经是2本书的
作者：《How To Raise & Train Your Peppermint Shrimpr》和《The End of
Cancer: Seeking A New Understanding To Defeat The Enemy Within. 》

I have always been fascinated by sex. The sex lives, of animals, I
mean. It doesn't matter if we're talking about birds or frogs or fish
or any other beastie, I always try to get them to breed in captivity.
My motto is: if it don't breed, it ain't happy.

我一直着迷于繁殖。我们谈论动物，青蛙和其他小动物的性没什么禁忌，我一直
试图繁殖他们。我认为：不繁殖，因为不幸福。

If an animal attempts to reproduce in captivity, I consider it a sign
that it's both healthy and happy. If it's not healthy, it won't have
the energy to go through the motions. And if it's not happy — meaning
that the environment you've provided doesn't "feel quite right" — then
it will be too uncomfortable or stressed to think about sex.

如果缸子里面的生物试图繁殖，我认为那是他们幸福并健康的信号。如果不健康
，那么他们也没有能力做繁殖运动。并且如果他们不幸福，这意味着你没有提供
给他们舒适的环境，导致他们不舒服或者没有淫欲。

So, if you're here to learn about breeding shrimp in captivity, it
means that you are probably not a rookie aquarist. You've (hopefully)
mastered the basics of aquarium-keeping, as much of your success will
depend upon good water quality.


所以，如果你准备繁殖虾，这就说明你可能不是一个水族初学者。你已经学会了
基本的水族维护，同样你也有可以依靠的水质。

I am going to focus my talk on the Peppermint shrimp, Lysmata
wurdemanni, because, in my opinion, it is one of the easier aquarium
shrimp to breed in captivity, and the larvae are "fairly" hardy. I put
the word "fairly" in quotes because at first it may not seem that way,
but once you get the hang of it, they are not too hard to raise.

我主要谈论的是关于薄荷虾，因为在我的观点中，这个是最容易人工饲养的，并且他的幼苗“异常”坚强。“异常”我用引号标示是因为首先并不完全是那个样子，但是你一旦掌握方法，他不是很难养殖。


I have experience working with other species of shrimp, so I may be
able to answer some questions on other species later.

我有另外2种虾的经验，所以稍晚一点我也会回答关于这其他品种虾的问题。

I am unsure of how advanced my audience is, so I am going to pretend
that you don't know very much about Peppermint shrimp. Peppermint
shrimp, like many marine animals,  are hermaphroditic (which used to be
considered unusual for shrimp). An individual shrimp can operate as
both a male and a female. All you need to make a pair is to have 2
shrimp in an aquarium.

我不知道大家水平如何，所以我就默认为大家对薄荷虾一点都不了解。薄荷虾，
像其他海洋生物一样，是雌雄同体的（这个曾经认为对虾来说比较少见）。一只
虾可以在雌雄之间转换的。所以要想配上一对，放2个虾进缸子就行了。

I'll address some differences for 2 other species in the genus Lysmata
(such as the Blood or Fire shrimp, and the Skunk or Striped Cleaner
shrimp) later, if anyone is interested.

晚点，我将谈到Lysmata科的两种虾的差异（火焰和清洁虾），如果有人感兴趣的话。

You don't need to have an expensive reef tank setup and high-tech
filtration equipment to raise shrimp. A simple 10 or 20 gallon aquarium
with an undergravel filter can work for the parent shrimp. A bare (no
filtration) 20 gallon tank will work for raising the larvae, although
inventive people may try other ideas once they've mastered the basic
techniques.


养虾，你不需要有珊瑚缸经验，也不需要高技术过滤系统。一个简单的10到20加
仑的底滤水族缸，就可以养活一对虾。一个裸缸（没有过滤）20加仑的也可以养
活幼虾，一但他们精通基础技术，也可以用其他方法。

The spawning tank should have a lots of rocks and hiding places to make
the shrimp feel comfortable. Peppermint shrimp breed pretty much all
year around, so the "day length" and water temperature aren't too
important. Just keep them constant.


用于繁殖的鱼缸要放入很多石头和提供给虾一些可以隐藏的地方，让虾感觉舒适
。薄荷虾机会一年不挺的繁殖，所以“日长”（估计是灯光开启时间，译者注）
和水温不是非常重要。只要保持他们稳定就行了。


I usually keep my lights on a timer set for 16 hours of daylight. The
water temperature is usually around 80 degrees

我通常保持灯光，准确的设定为16个小时。水缸稳定为80度（肯定是华氏）。

The next thing after a good environment is to feed them well. They may
spawn even if you are feeding them only once per day, but the larvae
you get will be very few and weak.

还有就是给他们好的环境和食物。它们可能会大量产卵，即使你每天只为一次，
但是幼虾你将得到很少而且体质很弱。

You get hardier larvae if you feed their parents at least three times
per day with high quality foods.

如果你每天喂食3次高品质食物，你将得到非常坚强的幼虾。

Mating usually occurs immediately after one shrimp molts its shell. The
actual mating takes no more than a few seconds. The shrimp acting as
the male will swing under the shrimp that just molted. Later that
afternoon, the newly molted shrimp will have a new batch of eggs
attached to "her" pleopods (aka "swimmerettes").

交配一般发生在他们脱壳后。实际交配持续不到几秒钟。公虾将游到母虾下面。
在午后刚脱壳的虾就将有一堆卵挂在虾游泳足上（肚皮的脚上，驿者注）。

Because the shrimp are both sexes, both shrimp will eventually carry
eggs. The eggs take about 10 days to 2 weeks to hatch, depending on your
water temperature. AS the eggs get closer to hatching, they will start
to turn a grayish-silver color. If you shine a flashlight on them, they
will reflect. That reflectiveness is the individual eyes of the larval
shrimp within the eggs.

因为是雌雄同体，所以可能2只虾都带上蛋。大概经过10到2个礼拜的孵化，这个要看你缸子的温度。当卵快要孵化时，他们经开始变成银灰色。如果你用手电筒照射他们，他们会反光。反光的是即将孵化成幼虾的眼睛。

The eggs always hatch at night after the lights go out. You can hand-collect them with a small siphon made of airline tubing, and a flashlight. The larvae are attracted to light and will gather in its beam. Siphon them gently into a cup or bucket and transfer them to their larvae tank (discussed in a minute).

在晚上灯光消失后，卵开始孵化破壳而出。你可以使用手电筒和气泵用的塑料管，利用虹吸原理来收集他们。浮游的幼虾会被灯光吸引，聚集在手电的光柱中。利用虹吸管轻轻的把他们收集到杯子或者水桶中转移他们到你的幼虾缸（马上就会提到）里面

If you like your sleep, as I do, you can invent a larvae collection device that uses a night light to attract the larvae to a safe area, where you can find them in the morning. In my book, How To Raise & Train Your Peppermint Shrimp, I describe one idea. The Larvae Collector can even be used in a reef tank system, so you can collect larvae without disturbing the rest of the tank.

如果你像我一样喜欢睡觉，那么你可以制作一个黑暗中利用光线吸引幼虾到一个安全的地方，直到第二天早上你可以找到幼虾。在我的书中 How To Raise & Train Your Peppermint Shrimp，我描述了一个想法。幼虾收集器可以在珊瑚缸里面使用，因此你不用可以收集幼虾而不影响到整个缸子。

The simplest larvae tank is a 20 gallon aquarium with no filtration,
only a small airstone in one corner to gently circulate the water.

最简单的幼虾缸是没有过滤的20加仑的水族箱，只需要一个气石在角落里面提供柔和的水流。

cuihaowei

The first 2-4 inches of water in the larvae tank should be water from
the parent's aquarium. That way the newly-hatched larvae experience no
changes in their environment, other than location. Gently pour in the
larvae so they don't bang the bottom or sides of their new home.

在繁殖缸里最先的2到4英尺要使用亲虾缸中的水体，这样新孵化的幼虾不会感觉到除了场所以外还有其他的什么改变。缓缓的引入到不要是幼虾碰撞到缸底或者缸壁上。

Every day after that first day, you can slowly add a gallon of clean saltwater, using the airline tubing siphon to dribble it in. Any sudden changes of salinity or temperature are stressful and often deadly to fragile larvae.

除了第一天以后每天，你可以慢慢使用虹吸管，引入清洁的海水。任何盐度和稳定的突然改变，都可能给虾带来压力并且导致柔弱的幼虾死亡

We'll discuss what goes on after the tank is full in a few moments.

马上我们就要谈到 在缸子被装满后要继续做什么。、


The best first food for Peppermint shrimp larvae is newly-hatched brine shrimp. The "eggs" and instructions are available at most aquarium stores. Other foods that they will take are finely ground flake foods or freeze dried foods.

对应刚孵化的薄荷幼虾最好的时候是刚孵化的丰年虾卵。丰年虾很容易就可以在大部分水族店购买。其他食物你可以使用薄片或者干的冷冻饲料。

Peppermint shrimp "reach" for food much larger than themselves, and they are able to "chew" on a piece of food, unlike fish larvae.

薄荷虾被食物“接触”多于他们接触食物，并且他们可以“咀嚼”食物，这点和鱼苗不一样的。

Once the aquarium is full of water, you will have to make small water changes, usually in conjunction with a bottom cleaning. Debris builds up on the bottom of the larvae tank, which degrade the water quality and may entangle the shrimp larvae, so it has to be removed. I use a 3/16" rigid tubing attached to airline tubing for a tiny "vacuum cleaner". After siphoning off debris, I replace the lost water with new saltwater (dribbling it the same way as previously described).

一但你缸被水填满，你要通过很吸取缸底垃圾，来进行少量的换水。堆积在缸底的碎片什么的会使水质下降，还会使幼虾粘附到上面，所以必须及时清理。 我使用3/16"的硬塑料管捆绑到气管上，当做一个小型的吸尘器使用。当垃圾被清理干净，我就用新的海水来补充被吸走的水（就想前面描述的那样慢慢的添加海水）

So, don't be lazy. Keep the bottom of the larvae tank clean. Feed just enough newly-hatched brine shrimp to keep the shrimp from starving, but don't overfeed, as too many brine shrimp saps the oxygen in the water.

不要偷懒，保持幼虾缸底部清洁。食物只要保持幼虾不挨饿，但是不能喂得过饱，过多的丰年虾会消耗水中的氧气。

Once your larvae are 4 weeks old, they will be big enough to take adult brine shrimp. You can usually find live adult brine shrimp at your local aquarium store, but if you can't there are instructions on the internet (or in my book ) on how to raise your own.

当幼虾4个礼拜大的时候，他们已经大到可以吃成年丰年虾。你可以经常在当地的水族店看到活体丰年虾，但是如果你不从网上或者我的书中看到怎么养活他们。

If all goes well, the larvae will begin to metamorphose from those little aliens into more shrimp- like creatures. They will be completely transparent at first, so it may seem like they suddenly disappeared, but keep looking. After 3-4 days, they will get their first stripes and
you may find them then.

如果你养的很好，很快幼虾就开始变态为更像虾的状态了。在他们完全蜕变的开始阶段，他们看起来好像突然消失了，其实他们还是原来的样子。大约3到4天后
，他们将长出第一个条纹这个时候就很容易发现他们了。

SInce I mentioned other species in the genus Lysmata (Fire/Blood shrimp
and Skunk/Striped Cleaner shrimp, I really skimmed through this. There
are plenty of details, but I will leave them for your questions. It
will take 5-8 weeks for the larvae to metamorphose. When they do, they
drop to the bottom and hide, even in plain sight.

现在我简单介绍下另外两种Lysmata科的虾（火焰和医生虾），我准备简略的介绍
下。有大量资料，但是我准备吧他们留个大家提问。他们大约花费5-8周时间才可以变态。如果他们变态，很容易发现，他们都会落到缸底，并隐藏起来。

I guess I'll finish that thought here. The Skunk/Striped cleaner shrimp
start off life as males and gradually turn into females as they get
larger. To make a pair, get a large one and a small one. AS the small
one catches up in size, they will both eventually carry eggs, but the
origianl female will do it more often.  Fire/Blood shrimp are both
sexes in the same shrimp, just as the Peppermint shrimp are but they
are aggressive with each other.

我想我就谈到这里。医生虾刚出生是雄性，慢慢的长的大的变成雌性。给他们配
婚，一个小的虾和一个大的虾就行。虽然小的可以可以带上卵，但是大的带卵的
时候比较多。而火焰虾是雌雄同体的，这个和薄荷虾是一样的，但是火焰虾有侵
略性。

cuihaowei

They have a kind of Klingon relationship. (For those of you who don't
know about Start Trek, that means they are rough with each other. To
make a pair you must have 2 of nearly the same size.  That way, they
can box with each other, but they will be equals, and will soon back
off and live together.

他们有近的亲属关系。如果你不知道Start Trek，这意味着他们彼此之间比较难
和平相处。为了配上一对，你必须找体型相近的两只虾。他们可能互相攻击，但
是彼此是平等的，所以很快就会彼此退让并一起生活。

If one is smaller, it will be weaker. They larger one will chase it
around and around the tank until it dies or gets far enough away.

如果一个小一些，这只就处于弱势。比较大的一直将驱赶这只虾直到他死亡或者
被赶得足够远。

AS far as larvae are concerned, Blood/Fire shrimp larvae are hardy
likethe Peppermint shrimp. It is harder to observe the eggs on the
adults, however.  Skunk/Striped Cleaner shrimp have larvae that do not
"reach" for larger foods. They prefer smaller particles of food.   
A good first food for them would be a combination of rotifers and
newly-hatched brine shrimp. But I could go on and on. I guess I should
go to questions now, to see what folks are more interested in knowing.

幼虾到是没那么多烦恼，火焰虾幼虾和薄荷虾一样坚韧。然而，发现火焰虾带卵
是比较困难的。清洁虾无法“接触”到大的食物。他们更喜欢小而碎的食物。好
的开口饲料对应他们来说是轮虫和刚孵化出的丰年虾幼虫的组合。但是我不能继
续了。我想我要结束这个问题了，去讨论成虾将更有兴趣。

This was a real crash course, and there are plenty of details lacking.
The main detail, however, is what I call the flick-of-the-wrist stuff.
Practice makes perfect.

这真是个速成班，并且缺少大量的详细资料。只有一些主要的信息，然而这家都
是关键资料。实践检验真理

I have no idea how long this talk is supposed to be, so I will turn
this over to the question/answer part now.

我不知道这次对话要持续多久，所以在这里开始回答大家问题吧。

Q: What type of light should be used on the nursery tank?
Q:孵化缸用哪种灯光比较合适。

A: Not too bright. A single florescent bulb is plenty of light.
Spectrum of light does not seem to matter.  Blood/Fire shrimp larvae,
however, do seem to drop to deeper portions of the larvae tank as they
get older. They may require less light

不用太亮。一个灯泡就可以提供足够的灯光。光谱也不是很重要的。对应薄荷虾
来说随着长大，他们将降到更深的地方。他们或许需要弱光。

Q: Whats the average # of fry and whats your average % that make it to
adulthood

Q:每次出生的虾苗是多少，又有多少可以长到成虾

A: For Peppermint shrimp, 100-300 larvae. For Fire/Blood shrimp, up to
600 larvae.  For your first 10 tries, you may get zero survival until
you get the hang of things.  After that it will increase. 20-40% is
average.

A:对于薄荷虾来说，100-300 只幼苗。对于火焰来说，一次最高可以达到600只。对
于开始的尝试，直到你掌握技巧之前，你可能存活率是0%。随着成活率的提高，
一般平均成虾率为20%-24%。

Q: This past year I spent a lot of time with L. debelius zoeae and
found that they only took pureed shrimp as a supplemental feed. I'm currently working on a planktonkreisel upweller that is designed to
keep frozen shrimp in continuous suspension. Have you done any work
with upwellers?

Q:在过去的几年中，我花很多时间在火焰虾幼苗（蚤状幼体）上，并且发现他们
只吃作为追加食物的虾泥。我现在采用的是“planktonkreisel upweller”，这
个设备能保持冷冻小虾持续漂浮。你采用什么设备保持食物悬浮么？

A: Yup. They work... but not well with nonmoving foods. Frozen foods
tend to degrade the water quality quickly.  They have all the correct
attractants, but those same attractants pollute the water. Newly
hatched brine shrimp work best because they are alive and stay in
suspension. Supplementla foods have to experiment with. Certain dry
foods work better than others.  As a side note, I have worked with
PLENTY of different supplemental foods. One that stays in suspension
wellis "GoldenPearls", but its nutritional quality doesn't seem
adequate.  Shrimp larvae eat it, but eventually die. Good Luck with the
Kreisel.

A:是的。但是，最好不用那些不会游动的食物。冷冻食物会很快降低水质。冷冻
食品可以很好的诱惑小虾，但是同时也在诱惑水质。新孵化的丰年虾幼虫是很不
错的，而且他们一直活着而且漂浮在水中。额外食物主要是实验性的。某些干燥
饲料效果可能比其他好些。额外说些，我曾经试验过大量不同的额外添加饲料。
其中有一款叫“GoldenPearls”的，其漂浮行比较好，但是他的营养成分就不是
很好了。幼体虾吃这个饲料，但是依然死亡。Good Luck with the Kreisel.

Q: How long do you have to feed Skunk shrimp Rotifers before moving on
to larger items?

在将幼虾移动大缸前，你喂多久Skunk shrimp Rotifers（不知道是什么，可能是轮虫）

A: Usually no more than 2-3 days. Once they molt to the next stage, they are large enough to eat newly-hatched brine shrimp comfortably.

A:通常用不上2-3天。一旦幼虾进入下一阶段，他们就足够大了，可以舒服的吃刚
孵化的丰年虾了。

Q: Is there a reason why 20 gallons is recommended? Can a 5 or 10
gallon work just as well?

为什么推荐20加仑（大约60L水）？5加仑或者10加仑不能很好的饲养么。

A: I have found that 5 or 10 gallon tanks do not work too well. The
shrimp larvae bang the sides too often, among other reasons.  Larger
tanks than 20 gallons are great for water quality stability, but harder
to keep the appropriate amounts of food stcoked in 'em. 20 gallon is a
compromise.

A:我发现5或者6加仑的效果并不是很好。太小了，幼虾经常碰撞到鱼缸壁上。而
大于20加仑的缸子虽然水质更好，但是很难保持小虾接触到食物。所以20加仑是
比较合适的。

Q: Should I put some pvc fittings for larvae to hide in?

我可以放置一些PVC配件到缸子里面给小虾提供躲避，隐藏？

A: Larvae are pelagic. They are designed for an open ocean environment
where they don't run into things often. They don't have the instinct at
that stage to hide in anything. Later, after they settle to the bottom
as postlarvae, they will need hiding places. Once they are large enough
to move to a regular aquarium setup, that would be best.

A:幼虾是浮游的。他们的身体结构是适应在开发的海洋环境中，这就意味着他们
很少进入其他物体当中。后期他们隐藏在底部的物体当中，这时他们需要隐藏用
的物体。一档他们足够大的时候，放入这些物体是非常好的。

Q: Could you explain planton kreisel upweller. sounds like some kind of
device

Q:可以解释下kreisel upweller么？听起来好像是某种设备。

A: An upwaller is more or less what it sounds like: a large circular
container that has a flow of water from the bottom that gently
circulates the larvae around the tank and keeps food in suspension. It
usually has a central standpipe with an air collar or other device to
keep the larvae from getting sucked out of the tank. It can work as a
recirculating filtration system, or with a flow-through system (if
youare near the seashore). A hobbyists can buy/build one, but it's a
bit of hassle at the hobbyist level.

A:一个upwaller或多或少听起来是这个样子：一个大的圆筒状设备，通过水体向
上的水流保持食物悬浮并且可以让幼虾在水体中均匀分布。可以当做一个循环过
滤系统，或者水流系统（如果你在海边）。一个爱好者可以购买或者组建一个，
但是爱好者级别组建这个设备还是比较困难的。

cuihaowei

Q: Should you target feed larvae or will the larvae hunt for them?
A: Newly hatched larvae have to bump into their food before they
realize it is there. For the first week the concentration of food
should be higher.  After they get older, they begin to hunt more
effectively. If you have the patience, and want to see which foods they
prefer, you can spot feed them.

Q:你怎么投喂食物给幼虾或者是他们是自己捕捉？
A:刚孵化的幼体虾在他们意思食物所在之前是扑食他们碰到的食物。对于第一周
投入的食物尽量多一些。在比较幼虾比较大的时候，他们扑食效率会更高些。如
果你有耐心，并喜欢看到他们吃食物，你可以当场喂他们。

Q: Should I gut load the brine shrimp (with selcon or other additives)
for added nutrition?

Q:应该使用添加营养物质的丰年虾（使用selcon或者其他添加剂）

A: Newly-hatched brine shrimp do not feed. Their nutritional value is
their yolk reserves alone. Different srtains of brine shrimp have
varying egg yolk quality. The best brine shrimp eggs go to aquaculture,
the worst end up in aquarium stores...AFter the brine shrimp are a day
old, they begin to feed, and yes, it is much better to add selcon or
other additives then.

A:不要投喂刚孵化的丰年虾。因为丰年虾的营养主要在于其卵黄。最好的丰年虾
卵是水产养殖的，最差的就是水族店的了。孵化一天后的丰年虾，就开始需要进
食了，当然，最好是添加selcon或者其他营养添加剂。

Q: What shrimp species have you found to be the most challenging to
raise? Is the procedure the same with all the species?

Q:你发现那种虾最难繁殖？同样一种方法适用于所有种类的虾么？

A: The basic larvae tank works for most species. The only things that
change are the types of food, the number of water changes, the amount
of aeration, etc. Striped Cleaner shrimp (of the 3 I've mentioned) are
the biggest pains in the butt.  Other species, like bandded shrimp just
require different foods, but they aren't too bad.

A:最基本的幼苗缸可以饲养很多品种。唯一需要改变的就是不同的食物，和换水
的次数，通气量等。医生虾（我说提到的3种之一）是最让人痛苦的。其他的品种
，例如美人虾，就需要不同的食物，但是不是特别难。

Q: Martin Moe told me to pay close attention to water quality and
redox. I figured I'd use aggressive chemical filtration during feedings
with my kreisel.

Q:Martin Moe 告诉我注意力集中在水质和氧化还原作用上。我认为我会在
kreisel添加的食物过程中使用更加强效的化学过滤。

A: Well, chemical filtration also takes out the "good" chemicals as well. Don't be too agressive. There is such a thing as too clean.
Sterile water won't grow anything. The more primitive the animal, the
more it depends on its environment to supply its needs. Higher
organisms get their minerals, etc from their foods. Primitive animals
get some things directly fromthe water.

A:化学过滤也会带走很多“好”的化学物质。不要用过度强效的。水质太干净了
，什么也不会生长的。很多原始生物，更多的依靠环境提供他们所需要的物质。
高级生物才会从他们食物当中获取微量元素等营养。而原始生物则从水体中获得这些。

Q: Has any more advancements been made with settlement cues for
L.debelius or amboinensis?

Q:有没有更先进的技术关于医生虾或者火焰虾？

A: They've been successful with L. debelius in Texas and the UK. L.
amboinensis is raised frequently in Hawaiia. In hawaii, they are using
flow-through seawater. So any chemical cues are there (since
amboinensis is native to the area) With L. debelius, they seem to
simply "wait it out". Most larvae that require cues become less "picky"
as they age. In my opinion, the larvae seem competent to settle at 5-6
weeks of age. They have everything they need to settle. They just
don't. They often go 10,12,16 weeks before settling -- if at all.

Q:在德克萨斯州和欧洲有人已经成功的繁殖了这两种虾，在夏威夷医生虾已经频
繁的繁殖了。在夏威夷，使用的是流过的海水。因为是用天然海水（火焰虾的产地），所以微量原素已经不需再补充，他们需要的只是等待。
随着它们的成长，它们对水中的微量原素要求会慢慢降低。在我的印象中，幼体需要5，6周大，就比较耐活。他们拥有所有的幼体所需求的东西。但是他们并没有。通常要到10,12,16周大的时候幼体才比较耐活。

Q: any info on raising Stenopus sp.?

Q:有任何关于红圈美人虾的繁殖信息么？

A: The best success I had was accidental. I had a garbage can outside in the sunshine that I used for growing out brine shrimp. The water was brownish from the algae bloom, and had a few copepods as well as
regular additions of n-h brine shrimp. I did nothing, but watch the
larvae grow... And then the mosquito patrol folks came by and dump that
"icky looking" garbage can full of water.

A:最好一次，我偶然成功了。我在外面有一个垃圾桶，曾经用来孵化丰年虾的。
藻类很多导致水成褐色的，还有少量桡足类生物，有规律的添加一些丰年虾。我
什么也没做，但是发现幼体虾竟然长大了，并且向蚊子一样满桶都是，四处游荡
很恶心的样子。

Q: Follow-up question. Are stenopus (CBS et al) hermaphroditic too?

Q:接上面那个问题。他们也是雌雄同体的？

A: No. They are definitely born male or female. If you lose one half of
a pair and you have a known opposite sex, the only way to get them to
pair up (instead of killing each other) is to wait until the female
molts. Only when she is soft and weak will she allow the male to get
near her. After they've had a night of it, they are permanent couple.

A:不是的，他们是分雌雄的。如果你损失了一对中的另一半，并且你已经知道他
的性别，唯一的让他再次配对（而不是杀死对方）的方法就是等待雌性脱壳。只
有这个时候雌性娇嫩且虚弱，这是雌性才允许雄性靠近她。之后他们共度一夜良
宵后，他们就成为永久的一对了。

Q: Yet another follow-up :-): Are they sexually dimorphic? Any way to
sex them?
A: In general, the males are smaller. The females are larger. The
females also have a large purplish area in between their legs. The
easiest way to tell is when a female has ovaries full of turquoise-green eggs.
Q:哦，继续红圈美人虾的问题。他们性别不发生变化？怎么区分性别？
A:通常是的，雄性比较小，雌性比较大。雌雄的腿中间有一大部分紫色区域。简单的区分方法是雌性有青绿色的卵巢。


Q: Are there any commercial breeding programs of peppermint shrimps?
Are any specimen bred for the purpose of the aquarium industry?
A: Yes, 2 places that I'm aware of breed peppermint shrimp on an
occasional basis they don't make much profit, so it doesn't go on all
the time). Ocans, Reefs & Aquariums in Ft Pierce Florida, and Tropical
Marine(?) in the UK. I'm only rasing them on a hobby basis right now
。
Q:薄荷虾是商业养殖么，有什么品种繁殖是为了水族产业。
A：是的，我偶尔出售这2种，但是利润很小，不会一直持续的。Ocans, Reefs &

Aquariums 在弗罗里达, and Tropical Marine(?)在欧洲（估计是为这2个水族馆

提供虾）。我现在只出于爱好的目的繁殖他们。
因为是用天然海水，所以微量原素已经不需再补充。
“So any chemical cues are there (since amboinensis is native to the area) With L. debelius, they seem to simply "wait it out".

Most larvae that require cues become less "picky" as they age
随着它们的成长，它们对水中的微量原素要求会慢慢降低。

能配上自己的实验就好了，先理论好实践。

真是不错的资料，最近我也在研究繁殖问题，不过最近只是繁殖成功了一些淡水蟹。它们的幼体没有浮游期，直接是以蟹苗的形式诞生。相比之下要好繁殖许多。
