陸寄居蟹網絡日誌オカヤドカリブログ

【大紀元7月30日報導】(中央社記者郭乃瑜屏東縣三十日電)貝殼被人類撿走了，寄居蟹只好以人類丟棄在海邊的空瓶子為家！人為破壞，陸蟹過馬路到海邊產卵越來越少！墾丁國家公園管理處將於八月舉辦一系列的生態之旅活動，藉由活動讓民眾協助這些生物繼續生存下去。這一系列活動都無需事先報名，只要在活動時間前往活動地點即可。

墾管處八月份的系列生態活動有：「藍色夏日｜把貝殼還給大海」、「護送螃蟹過馬路」、「銀河之旅」。

其實事件本是很簡單.

所長/副所長你好,

聽台灣的朋友們說, 貴水產試驗所已經在去年成功繁殖陸寄居蟹這物種, 不知是否真有其事?

十分高興聽到這消息, 希望水產試驗所會和大家一起分享這研究成果.

我的一位美國朋友也正在研究如何能人工繁殖陸寄居蟹, 如可以的話, 可否寄一些相關資料給我

副所長,

你好, 那便奇怪了, 我得知

你們有位叫鄭金華先生的行政院農委會水產試驗所生物技術組(原東港分所) 研究員曾和台灣的業聯絡過, 說有關人工繁殖等問題.

 

而最近那位業者在其討論區內說水產試驗所的所長會寄相關成功人工繁殖的照片給他.

不知這事情到底是怎樣?

副所長,

謝謝你請研究員與我聯絡.

對不起, 因我的小小詢問, 好像使台灣水產所增加了不少麻煩.

世界各地到現在不能夠成功繁殖到陸寄居蟹, 如果水產所能成功, 可是一令人振奮的事, 也是世界首宗個案.

(Tony: 那便等待研究員的聯絡.)

是我做錯了嗎?

好消息... 

>剛剛接到蟹皇電話..得知台灣水產試驗所..於去年已繁殖寄居蟹成功.並上岸脫皮數次..近日所長會將照片寄給蟹皇..還請大家拭目以待(台灣ㄉ驕傲)下個試驗是椰子蟹唷..... 

Tony: 聽說台灣水產試驗所, 於去年已成功繁殖陸寄居蟹成功, 並上岸脫皮數次......

聽到這消息真的很高興, 但其實心裏還存有一個問題, 便是即使陸寄居蟹能被人工繁殖出來, 但如果自然環境仍然愛到人類破壞, 牠們在野外也很難找到生存空間.也真的希望繁殖出來的目的並不是為了有更多的數量供販賣.

今天我電郵去詢問, 得到的回覆如下, 有點奇怪:

最新消息, 來自蟹皇:其實大家的觀點都不錯，只是各位對於生態的見解都有一點模糊~~ 

對於政府介入繁殖陸寄居蟹一事，只是拿陸寄居蟹做研究開刀先鋒~~ 

其實最主要的目的防止(椰子蟹)物種的滅絕~~ 

拿陸寄居蟹做繁殖試驗的成功與否，都不會牽涉到法律責任與觸法~~ 

當然政府成功的繁殖陸寄居蟹相對的(椰子蟹)也能迅速的復育~~ 

捕捉販賣陸寄居蟹與沿海建設開發來比較根本微不足道~~ 

有空各位去台灣沿海公路環島一圈您就能明白了~~ 

沒有生長棲息環境，哪來物種延續~~ 

寄居蟹博士(施**副教授)曾經對我說過~~ 

只要能繁殖物種，誰都無法干涉捕捉與販賣~~ 

叫我朝著(陸寄居蟹)繁殖方向去努力~~ 

話說回來這幾天，經過我送去(水產局)的母蟹數量來估算~~ 

二十隻左右中型的陸寄居蟹，抱卵數量大約為二十萬顆左右~~ 

所以也跟(水產局)約定，今年六月開始~~ 

將無限量提供研究，希望有好的成績~~

Tony:

造成不便深感抱歉. 

首先, 是因為在STONE討論區消息是說"於去年已繁殖寄居蟹成功.並上岸脫皮數次..近日所長會將照片寄給蟹皇..還請大家拭目以待", 所以我直接詢問所長, 理應沒有甚麼問題吧.

不過如果那位研究者是從正當的途徑, 即透過水產局的認許來研究繁殖陸寄居蟹的話, 我想那位研究者不會被責罰, 除非是另有目的. 

若真的是由水產局正式的去研究陸寄居蟹繁殖, 我想這是值得高興的事. 

我只是想詢問清楚, 水產局是否真的成功能繁殖陸寄居蟹, 並希望水產局能夠在其網站內分享這些資料給大家, 就是這麼簡單. 

我所複製的文章(新聞), 信件(電郵), 或這裏討論區的文章(這裏不是人人能登入的), 也是想大家從中多了解陸寄居蟹的一切. 

對於你說"曾經有網友線上或來電說", 可請他們直接聯絡我了解一下.

2007/04/02

卓宇:是啊 它網站做的那麼好 用一些文章應該不會有什麼關西 而且又不是有什麼其他目的 而是要給大家更了解陸蟹啊 

2007/04/03

某蟹友: 官場文化是非常可怕的,除非是讓所聯絡的長官很光榮的事,否則,當我要為當事人好時,我會想辦法問當事人,若要害當事人,則直接去請教他長官 

卓宇:所以你是暗指TONY故意去陷害那位研究者囉?? 

Tony:

不過大前提是, 蟹皇說他會由所長那裏得到人工繁殖的照片, 所以直接詢問所長有甚麼問題!? 就是副所長回覆沒有樣的研究, 我才回覆水產所, 好像有位某某學者研究成功了(能成功繁殖陸寄居蟹這樣大件事, 當然想去了解清楚). 如果那位研究者沒有做不可告人的事, 即使我去問所長, 也不會影響那位研究生.

而且不是蟹皇說那位研究者可能是利用水產所的設拖來研究, 大家也不會知道這件事. 我能陷害那位研究者甚麼. 我一直期待人工繁殖的成功. 之前我在網上找到一些有關研究繁殖椰子蟹的文章, 都有叫蟹皇看看對人工繁殖有沒有用. 

以下是我在外國討論區所發表的文章(還有其他飼養者的回覆), 內容是說大家也知道橙紅陸寄居蟹是很難飼養的品種, 也業者還在不斷捕捉和販賣, 從另一角度來看, 其實我們正在殺害牠們......

Every one know Straws are the most difficult species that can be kept as pet in tank.

Most of them cannot keep them over 1 year. Until now, we cannot find more information on how to keep them well and healthy.

So, why supplier still imported, harvest so many Straws in the wild?

Just my own thinking, it seems that we are now killing that species.

It is good idea if we can know more about their natural life before keep them as pet.

However, there is no more detail about their natural life in the wild.

Just moving this topic to the Activism forum  

I agree with you 100% Tony. Would definately like to see more information available for pet owners to be able to keep all of their crabs happy and healthy, more needs to be known for sure.

Thought you would be interested to hear that in Australia, there are very strict guidelines on the practice of harvesting Straws. Only a couple of hundred can be harvested each year and in certain areas such as the Barrier Reef Islands, it is declared national park area and no harvesting of Straws can be done there.

It seems to me that this logic applies to all crabs, not just straws. Unfortunately it seems that here in the US, most people don't take hermit crabs very seriously. The folks here at the HCA are the exception, but the majority seem to view hermit crabs as 'living toys' for children. They don't expect a hermit crab to live more than a few months. Many hermit crabs are harvested and killed each year out of ignorance. And if you take your hermit crabs seriously, most people think you are strange or childish and you need to get a 'real' pet.

Hopefully, someone will figure out how to breed land hermit crabs in captivity. I think if we are able to do that, we will solve many other problems at the same time because in order to breed an animal, the condition and health of the animal have to be optimal.

**以下的飼養者說自己飼養了橙紅陸己有2年.

Personally I don't understand why there's so many people that think that straws are so very delicate. Before I moved (and had to re-home them) I had 3, I had them for just over 2 years, and they all molted multiple times without any difficulty (one was even a surface molt and still had no issues at all). None of them came from good pet store conditions, although the first two I got were only in the store for maybe 5-6 hours before I got there. None of them seemed the least bit stressed, and because of them tearing through the iso tanks I wasn't able to keep them in iso for more than a few days after getting them. I'm talking tipping dishes over multiple times in an hour, dumping food everywhere, digging sand into everything- this went on day and night when I first got them and was trying to iso.

I keep all my crabs in playsand, the only time they're in contact with EE is when I grow them sprouts. I put one UTH on the back wall that's recommended for that size tank. I don't use heat lamps or any other type of lights, other than the light that comes in through the windows. One thing that I've done with my tanks that have straws (and I've gotten lots of flack in the past on here for saying this) is that I keep the humidity at 80%-85%. I'm not saying I keep it at 85%, I'm saying I let it go up to that, and I don't let it go below 80%. Mine anyways always seemed to become less active when it dropped below 80%, I also had e's in with them, and they seemed to also be fine in those conditions. I also always have dishes deep enough for them all to submerge in. Not all of them went in it right away, most of the crabs it takes weeks before they even try to go all the way in, but once they do they're in it more and more. In my opinion, the straws would be closer to the beaches in the wild, so naturally they would go into the ocean more often than other species.

I'm not saying any of this is necessary for them, I'm just saying that this is how I kept mine and I never had any problems with them or thought in any way that they were very delicate. I don't know if maybe it's because the first ones I got them almost right when the store got them in, but my third one was in appalling conditions and there were lots of dead crabs, and he was the most destructive and active in the iso. Also if I know I'm planning on buying new crabs (of any species), I always bring a tupperware container with me to transport them in that has damp paper towels in it. I think they've already been in contact with poor conditions for long enough, why prolong it with the car ride home? Just thought I'd share my experience with straws in general. I don't know if any of it's helpful or not, sorry it got so long.

Hi Tony  

I can't say that I know much at all about how they live in Australia. The only information that I have found out is that Straws here are harvested from islands and coral cays in the Coral Sea(off the coast of Queensland). 

It would be great to find out more information of course, that's something that I'm always trying to do, but in the mean-time there's a marine biologist that I know in my town and we've had a long chat about this, and he said that Straws have a high UV requirement and of course require high humidity levels. It would be nice though to find out more about their diet in the wild.

Nicaha, I think keeping straws in 80-85% is good, that's what I keep my Straw in

Hi nicaha,

Your 2years experience is valuable to us.

If you can share your Straws tank photo, then we can know more about the decoration of your tank. It may

help us.

Could you tell us more about your tank. e.g. 

-tank with spring water dish? 

-tank with salt water dish? 

-what food you always feed them? 

-what temperature you keep (use UTH to keep the temperature)?

You said "don't understand why there's so many people that think that straws are so very delicate", but you

know, there are still many many people do not know how to take care their carbs, even their crabs are not

Straws. So, I really hope you can share more information with us.

2007年3月18日早上6時多:

我被家中的一隻小短腕陸寄居蟹挖沙的聲音弄醒了. 我知道這是牠脫殼完畢, 正在挖沙返回地面的聲音.....

因為已經睡不著了, 便起來看看牠的情況, 結果便看到牠已經脫殼完成, 而整隻斷腳也完整長回來了.

2006年9月22日

先說為何會有這隻小短腕, 其實是一位友人在06年9月中時給我寄養的. 他還給了我一隻小型的深紫陸寄居蟹. 很巧合,兩隻陸寄居蟹也是斷了一整隻胸足. 短腕斷了左邊第三胸足(下圖紅圈處), 深紫陸斷了左邊第二胸足.



本來也不想把小短腕公開出來, 但覺得斷腳再生這資料的確值得與大家一起分享的. 所以便打了這篇文章.

小短腕(前甲長10mm)到來後, 第一時間便從原來的螺殼搬到新給牠的螺殼內. 因為牠原先背著的螺殼實在太大了, 太大的螺殼很可能會影響牠的行動. 而新給牠的螺殼的大小則剛剛好, 當牠躲在螺殼時, 大螯剛好和螺殼口成一水平線. 牠在更換了螺殼後便躲藏在流木洞穴內, 一直沒有出來. 很奇怪, 我沒看過牠出來進食. 但在清理時卻找到一些食物的殘渣在牠身旁. 我想牠是在睡覺時把食物拖到牠棲身的流木洞穴裏.

2006年10月3日

牠己躲藏在海水盆的盆底裏. 之前沒有看到牠有挖沙的徵兆. 躲藏了9天, 返回沙面. 不過卻在翌日(10月12日)又再躲藏在海水盆底下, 又再躲藏了9天, 再返回來了. 從表面上看不到牠有脫過殼的積象. 不過當仔細看看其斷了的第三胸足, 便看到斷腳的位置己長出突起的芽狀薄膜(下圖紅圈處). 我想這次短期的躲藏, 長出來的芽狀薄膜便是為了將來的斷腳再生來作準備.



2007年1月26日

相隔了98天, 即3個多月後, 牠又再次躲藏起來. 這次牠是躲藏在淡水盆下, 和上次一樣, 這次躲藏起來之前又是沒有看到牠有挖沙的徵兆. 足足躲藏了51天. 到了2007年3月18日, 終於完成脫殼了(下圖), 斷了的胸足也整隻完全長回來了. 而且對比牠脫殼前的體色, 可以看到在脫殼後, 體色明顯地變得更鮮艷.



看到這情況真的十分感動, 也很讚嘆甲殼類動物的再生力量.
