幼体

A Lagrangian model is presented of the current-carried migration of the leptocephali of the European eel across the North Atlantic Ocean from the spawning area in the Sargasso Sea to the adult range in Europe and North Africa.

拉格朗日模型模拟了欧洲鳗的幼体随流洄游，横过北大西洋从马尾藻海的产卵场到欧洲和北非的成体生活区域。

This study reviewed literature on spawning times for three north temperate species of anguillid eels estimated by sampling for small leptocephali at sea and for several temperate and tropical species by back-calculating from putative daily ages derived from otolith increment analysis of glass eels that recruited to coastal waters.

本文通过研究了海里采集鳗鲡幼体总结出的三种北温带种类的鳗鲡的产卵时间，并且通过通过分析溯河洄游到淡水的鳗苗的耳石日龄倒推出的产卵时间，将二者进行比较研究。

Several basic tenrts of otolith research have been questioned recently with regard to eel metamorphosis.specifically,some researchers have suggested that otolith increment formation is not daily,and otolith material may be resorped during metamorphosis.we conducted a rearing experiment to test the hypothesis that increment formation is daily and that the otolith continues to grow during eel metamorphosis.we marked the otolith of wild-caught leptocephali and reared these fish through metamorphosis.metamorphosis was characterized by a decreasing standard length,pre-anal length,and body depth accompanied by an increase in pigmentation and a change in behavior.

最近学者关注的鳗的耳石的研究的几个最基本的问题涉及到鳗的变形。尤其是很多研究者认为耳石的日轮沉积并非是每天的，耳石的材质可能是会在变态过程中被重吸收一部分。我们做了个养殖的实验来测试鳗鲡耳石的形成的每天一轮而且在鳗鲡的变态发育阶段耳石是在继续生长的。我们标记了野外捕捞的蠕鳗幼体，养过变态期。变态期是通过标准长度，肛前长和体高的减少和色素的减少以及行为的变化来定义的。

The bio-toxicity of the dinoflagellate Alexandrium minutum on black seabream was studied by observing the acute toxicity and subacute toxicity of A. minutum on the S. macrocephalus embryo and larvae. The presence of A.

Liaoning Panjin due to climatic factors, the beginning of June Megalopa supply.

辽宁盘锦因气候因素，6月份开始供应大眼幼体。

May Megalopa of sales affected by market conditions, prices also fell the same period last year, of which the largest decrease is Sanae, 100 yuan lower than last year / kg around for 120-150 million / kg; soil pool seedlings showed smaller decreases 300-330 million in the current price / kg, compared with last year fell 10 per / kg about.

5月份的大眼幼体销售受市场环境影响，价格较去年同期也有所下滑，其中跌幅最大的是早苗，较去年降低100元/kg左右，为120-150元/kg；土池苗跌幅较少，目前售价在300-330元/kg，较去年下跌10元/kg左右。

In May, the South Main crab fry production areas (Jiangsu, Shanghai, Anhui and other places) Megalopa available, will continue until early June, after the deduction to stop the supply of Crab species.

5月份，南方主要河蟹苗种生产区开始供应大眼幼体，将持续至6月初，此前的扣蟹苗种停止供应。

Crab,reproduced in man-made brackish water,camouflaged by aquatic weed,fed on meal made of crayfish and fresh fish and maintained in qualified water,are cultured seperataly from megalopa to Ⅲ-stage larval in cage,cement pool and pond.

利用网箱、水泥池和池塘分别培育人工半咸水繁殖的河蟹大眼幼体至Ⅲ期仔蟹，以水草为隐蔽物，新鲜鱼、虾等肉糜为主要食物，保持良好水质；采取上述技术措施，网箱内培育的仔蟹成活率为75％、水泥池达86％、池塘为40.5％。

The mittened mini-monster was first recorded in Britain in the Thames in 1935 having almost certainly arrived as larvae in the ballast water of ships from the Far East.

据记载，英国1935年最早在泰晤士河发现这种&戴着拳击手套&的小怪物，它们十有八九是幼体时期随着远东船只的压舱水来到这里的。
