即使海洋学院一直在努力解决大约十年的守则,圈养的黄色唐斯似乎总是只有一两年的路程。被囚禁的苏格里犬相对简单,但是将小幼虫饲养到成年后,事实证明是圈养的育种观赏鱼的圣杯之一。
四年前,在互联网的回声室中,有些错误信息参加了巡回赛这似乎支持了这样的观念,即黄色唐人确实被俘虏了。尽管它们在技术上是“俘虏的繁殖”,但这些后代从未超过几周的幼虫持续时间,这在任何方面都不是实际的成功。
在随后的几年中,海洋研究所永远不会放松繁殖Zebrasoma flavescens,and they’ve been pushing and trying every kind of larval diets they can to get their yellow tang larvae to live longer and longer. Last year Chad Callan announced that theirlarval yellow tangs had passed the 50 day milestone黄色唐人似乎即将到来。
Alas, another year has passed and no baby yellow tangs have settled from the prodigious quantity of larvae that the Rising Tide project is producing. However, this week the Oceanic Institute announced that they’ve now gotten their yellow tangs to the 70 day milestone and these fish really do look like they’re right around the corner from being teeny tiny little yellow tang juveniles.
The 70 day old (post hatch) larvae of yellow tangs that Chad Callan and crew have managed to raise are starting to round out in shape, and we can even see hints of some pigmentation developing in some parts of the body, notably the head and the tail. At this point, we have pretty good documentation on the外貌of pre-settlement and post settlement yellow tangs, and it truly seems like the Oceanic Institute needs to push through just a little bit longer to get their baby fish to settle out.
这些圈养的黄色唐人的另一个重要里程碑是背鳍的发展,它单一的变化从上层自由浮动幼虫到准备在礁石上游泳的自导向的移动鱼。
黄色唐的成功不仅意味着水族馆的爱好最终将享受可持续的圈养黄色唐人,而且我们甚至可能期待看到有关的技术Z. flavescensbeing applied to a large number of other surgeonfish species. The captive bred yellow tang larvae are lasting longer and longer and any day now we expect to read an announcement from Rising Tide that they’ve finally broken through the captive bred surgeonfish barrier.
