陸寄居蟹網絡日誌オカヤドカリブログ

4月3日收到了水產試驗所 副所長的電郵, 說已通知那位研究生直接與我聯絡. 但到現在, 整整一個月了, 仍然收不到那位研究生的回覆.

上星期再一次電郵給副所長, 也沒有了回覆. 其實我一直也沒有否定水產局能成功人工繁殖/人工孵化陸寄居蟹. 只是我總會愛凡事問過究竟.

我想此事就此告一段落吧.  希望有一天我是會在新聞裏看到有關成功人工繁殖陸寄居蟹的消息.

但其實個人認為人工繁殖只是沒有辦法之中的消極辦法. 人工繁殖只是希望能增加牠們的數量, 不要讓牠們減亡, 再者其數量的增加並非為了讓人們繼續有得捕捉. 沒有危機, 便不用人工繁殖吧.

要牠們不要步椰子蟹的後路, 保護牠們的棲身環境, 減少濫捕才是首要做的事. 因為棲身環境要是被破壞, 即是數量多也不能生存. 數量多但又過份被捕捉的話, 牠們能繁殖下一代的機會也會變少.

簡單來說: 保護棲身環境->數量自然會得以維持->加上沒有被濫捕->能成功繁殖下一代的機會增加->下一代又能在良好的環境下成長.

有人說陸寄居蟹和椰子蟹不同, 因為陸寄居蟹在某些地方數量還十分的多, 多得不能想像. 而且那些地方還未被人類開發. 而且椰子蟹的數量大幅減少, 和牠們被人當作食物有關. 所以陸寄居蟹究本不需要保育. 如果說椰子蟹數量減少是因被食用而被大量捕捉, 那陸寄居蟹被也不是因被作寵物而大量捕捉嗎? 而且現在地球環境每況愈下, 不少動物原來的棲身環境也遭人類日漸破壞, 不要少看人類的力量, 當動物棲身環境被壞, 牠們的數量被會一時之間大幅下降, 甚至整個族群也會被滅亡. 大家可以綠島為借鏡. 而還未被開發的地方, 終有一天會被人開發的, 大如亞馬遜森林, 近年來也不斷被人開發, 樹木被砍伐大大減少, 沒有樹木, 生態很難維持.

椰子蟹在之前數量也是很多, 為何現在數量少到要立例保育呢? 反過來看, 很多動物的命運也可能一樣.

人類很聰明, 懂得運用地球資源, 但最後人類可能變成最蠢的生物, 因為我們的地球會被自己的聰明而破壞, 看看全球暖化現象便知, 聰明反被聰明誤, 人類最後也不能鬥過大自然.  

在這裏分享一篇我看到的保育文章, 很有意思的. 雖然這篇說的是關於龜鱉類動物, 而不是陸寄居蟹, 但也希望有朝一日大家也會讓文章中的作者般, 愛珍所喜歡的動物.

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?

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.

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.

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.

和之前的日文書籍<ProFile100別冊 陸寄居蟹> (プロファイル100別冊 オカヤドカリ)一樣, 又要由日本業者Okayadokari Park協力出版的書籍...... <齊來飼養陸寄居蟹!>(オカヤドカリを飼おう！)

雖然圖片的確拍攝得很漂亮(下圖), 但其內容則不太認同. 不過其實未看之前, 看到是以彩繪螺殼作封面, 己覺得其內容好極有限.


首先看著者的介紹, 小林道信先生只是一位水槽攝影家, 所以書內的圖片拍攝得十分美, 果然是專業水準. 不過看完後, 個人便覺得其內容所介紹的飼養方法的確有點問題. 雖然書籍主要是說明陸寄居蟹的飼養方法, 但卻有點兒是為了宣傳那間業者和其售賣的產品.

以下是個人一些主觀看法:

1. 在第一版的序那篇文章寫了一句:「成体になっても全長が10cmにも満たない小ささのお陰で、大きな飼育容器が必要ないことも、とんな家庭でも飼えるミニミニ・ペットとして、とても人気が出た大きな理由の一つです。」, 其意思是「陸寄居蟹長大後的成體, 因為全長也不會超過10cm, 所以並不需要大的飼養容器, 牠們是任何家庭也能飼養的迷你寵物, 這是牠們大受歡迎的其中一個原因.」, 個人覺得讀者看了後, 會自然覺得陸寄居蟹十分容易飼養, 而且只需少少空間便行. “任何家庭也能飼養的迷你寵物”這句也有說得太誇張了, 飼養牠們我們必須有足夠的設備才行, 並不是任何家庭也能飼養.

2. 另外第3章雖有詳細說明如何佈置飼養缸, 書內的熱毯放置方法如下圖, 整張熱毯完全佔據了飼養缸的底部. 但關於熱毯的放置方法個人卻不太認同. 個人在網站內也有曾介紹熱毯放在飼養缸底的方法, 但重點是熱毯不要完全佔據了飼養缸的底部, 因為如果鋪了熱毯那地方的溫度太熱的話, 這樣陸寄居蟹便沒有逃走的空間.



再者熱毯鋪了在底部, 熱力會由下往上. 當陸寄居蟹要脫殼時牠們會往下挖掘沙堆, 如整個飼養缸底部也鋪了熱毯, 這樣便會影響了牠們挖沙脫殼, 嚴重的話可能會使牠們不能挖掘到適合的躲藏地方脫殼而死亡.

如果讀者真的好像書中的方法擺放熱毯, 真不知道會有甚麼後果.

3. 在Q&A那部分裏

Q6, Q: 如在一些玩具店看到有販賣陸寄居蟹, 看到牠們很可愛, 但卻好像很脆弱, 那應該把牠們帶回家?

A: 那些店鋪的人是一些不懂得照顧陸寄居蟹的人. 如果你幫牠們購買, 當店內的陸寄居蟹全賣光後, 他們便會再進一些新的個體, 這樣只會犧牲新進的陸寄居蟹. 只要不幫牠們購買, 他們就不會再進陸寄居蟹, 這樣便不好白白犧牲了牠們.

Q7, Q: 那麼我們應該在那些店鋪購買?

A: 可向一些有專業短識, 誠實, 即使購買金額少的客人也會好好對待, 這些店鋪, 而這些店鋪也適用於網上販賣.

看完這兩題Q&A, 十分可笑, 其實這兩題的意思只是想說不要到其他店鋪購買陸寄居蟹, 要購買的話便要到專業的Okayadokari Park. 為何我會這樣說, 因為正正就在Q&A後的著者介紹那一版, 便寫著製作協力是陸寄居蟹專門店Okayadokari Park, 還寫上了網址. 這還不是宣傳嗎!? 真覺得這兩題Q&A是自己作出來自問自答的.

4. 最大的問題是一本教大家如何飼養陸寄居蟹的書籍, 竟然沒有說明對陸寄居蟹十分重要, 關乎生死的事情-脫殼, 不單隻字不提, 整本書連有關於脫殼的一點資料也沒有提及. 對於初飼養者來說, 如果看完這本書後, 會有甚麼問題!? 因為讀者連牠們要脫殼, 脫殼是甚麼也不知道, 當牠們所飼養的個體挖沙躲藏將要進行脫殼時, 他們可能只把陸寄居蟹當作只是挖沙的動作(因為書裏只提及陸寄居蟹喜歡挖沙, 但沒有說明是甚麼原因), 不懂的話很有可能會做出些干擾的行為, 影響了牠們脫殼, 使牠們死亡. 脫殼是陸寄居蟹在成長中最重要的一環......

而自稱是陸寄居蟹專門店的Okayadokari Park, 在協力時沒有提供有關脫殼的資料, 這到底是一本甚麼的飼養書籍!!!
