由密歇根州海洋生物水族馆协会(Masm)和海洋育种计划(MBI),并于2014年7月19日在Cranbrook Institute of Science在密歇根州的布卢姆菲尔德山(Bloomfield Hills),这是他们仅针对海洋物种的圈养育种的第五次研讨会。
这种方法支持水族馆业余爱好的可持续性,并为家庭水族师提供了传播家园中海洋水族馆动物所需的信息。成功地养育自己的动物的水族师始终学习技能,以改善水族馆的整体水平。
知道网络至少与演讲本身一样重要,MBI组织了一个工作前的接待和工作后的烧烤,使与会者可以与扬声器交互,并在非正式环境中获得更多的见解。
我过去曾参加过这次会议,并在Toledo Zoo为传播狗鱼的努力以及我们的飞行员海洋繁殖计划。
Here are brief descriptions of the day’s presentations:
1.The first speaker was Matt Pedersen, an editor for珊瑚和亚马逊杂志,谈到小丑鱼的物种和品种。他觉得(就像我一样)两亲leucokranos和A. theilli不是有效的物种,而是自然发生的杂种。他还觉得黑色Ocellaris来自达尔文的小丑鱼足够不同,可以保证是一个单独的物种。
2.来自佛罗里达Institute of Technologyspoke on some coloration enhancement studies he had performed. He also gave an overview of the scientific method and basic statistics for citizen scientists. His study found that additions of carotenoids at a rate of 75 to 150 ppm in food gave the best results. He also discussed how meaningful results can be obtained from a study without having to perform huge numbers of replications; time can be a factor, as can separate “runs.”
3.Matt Pedersen spoke again, this time on clownfish genetics. He made a brief mention of something that I suspected many years ago—that some clownfish “varieties” are a result of “chemical treatments.” He didn’t say how widespread this practice is, but I suspect it was more common in the past, and probably involved the use of steroids. This non-genetic phenotype plasticity usually results in misbar coloration.
4.Dr. Roy Yanong from the潮汐保护上升initiative and theTropical Aquaculture Lab是该国顶级水族馆兽医之一。他谈到了疾病过程,并使用电子反馈系统对观众进行了询问。他的演讲中有四个重要的带回家信息:
- Virkon-S is the most effective net dip disinfectant to use.
- 亚硝酸盐在喝水时可能会被海鱼吸收。
- 卵质注射可以在卵结合的情况下使用。
- Copper treatments must be ramped up slowly to avoid acute toxicity.
5.Karen Brittan, formerly an aquarist at the威基基水族馆,现在与一家水产养殖公司一起自由职业者进行了Skype的演练,她的家伙育种业务。她已经传播了许多神父物种Centropyge和Genicanthus. Her operation did not look like anything another home aquarist couldn’t easily duplicate. However, she does have access to wild-collected plankton and to natural sea water from the aquarium.
6.Matt Pedersen gave his third talk of the day on hybrid clownfish; easy, effective, but ethical? There are some cross-genera hybrids being produced (Premnasx两亲). The risk here is that some of the phenotypes of these fish are not changed enough to keep them from being accidentally distributed as one of the parent species. However, their genotype is different, so if they are later bred against the species of the parent they resemble, hybrid genes will enter that population without the aquarist being aware. Matt also discussed copyright and creative commons laws as it relates to using images from the Internet.
7.安迪赖恩表示从博士New England Aquarium/罗杰·威廉姆斯大学, spoke on aquarium fish culture. I attended a five-day workshop he held earlier this year, and his information is very helpful for would-be home aquaculturists. Dr. Rhyne’s lab is releasing small numbers of tank-raised fish (resulting from various studies) to the hobby through select dealers—notably Catalina gobies and fire shrimp. The Toledo Zoo has one of his modular marine fish propagation systems. Once the水族馆翻新is completed, we will use it to raise clownfish and other marine animals.
This workshop is gaining momentum each year and may soon reach beyond the local Midwest audience that it now mostly serves. MASM also held a general conference (usually in March) that had a vendor area and was more reef aquarium related. Their website has not been updated, so it is unknown whether there will be a conference in 2015.
