Algorithms describing links between potentially important explanatory variables to estimate fecundity were first established, and these were followed by practical observations in order to validate the method under two extreme situations: 1 straight forward fecundity estimation in a determinate, single-batch spawner: Atlantic herring Clupea harengus and 2 challenging fecundity estimation in an indeterminate, multiple-batch spawner: Japanese flounder Paralichthys olivaceus.
首先确立潜在重要解释性变化与繁殖力间联系的算法,然后是为了确定下面两种情形下使用的方法的实际观察:1)在确定的单次产卵类型中直接的繁殖力估计:大西洋鲱鱼 Clupea harengus 2)确定的分批产卵鱼类竞争性的繁殖估计:日本牙鲆 Paralichthys olivaceus 。

The level is higher in the breeding time than in the non-breeding time. The change of T level is significantly correlated with the breeding season. The change of T level of the male Equus hemionus is significantly correlated with the seasonal change of a lot of breeding behaviors, illustrating that the breeding behavior of the male Equus hemionus is regulated by the T secreted by the testis.
雄性蒙古野驴的T变化水平与很多繁殖行为的季节性变化显著相关,说明雄性蒙古野驴的繁殖行为是受精巢分泌的T调节的,T分泌的季节性波动是雄性蒙古野驴繁殖行为季节性变化的生理基础。

Nov. mainly inhabits those channels such as mahuang channel、gari channel、bori channel、heping channel and dengchi channel. So it belongs to the distribution area extremely narrow type. From May to October 2005 and May to August 2006, 671 specimens collected were used for studies on the reproductive strategies such as reproduction time, spawning type, the ratio and the fecundity, and gonad development and characters of early life history. The main results are as follows: 1.Every year speaking of spawning season the male"s is earlier than female"s slightly.
Nov。仅分布于宝兴河支流东河盐井以上河段,主要分布在蚂蝗沟、嘎日沟、波日沟、和平水域及邓池沟,属于分布区极其狭窄的种类。2005年5月—10月和2006年5月—8月共采集671尾标本,运用常规生物学指标的测定分析法和性腺的组织切片法,以及对成熟亲鱼人工授精获得的胚胎在立体显微镜下活体观察,研究其繁殖期、产卵类型、性比和繁殖力等繁殖策略及性腺发育和早期发育。

Those parent abalones of wild or artificial selection with good economic characters must be chosen in order to avoid close breeding.. Correct breeding techniques must be adopted to obtain excellent germ cells and larvae. The survival rate and disease resistance of juvenile abalone can be remarkably increasedonce the further selecting and culturing are carried out. The rejuvenation is realized once a good breeding condition for the young and parent abalones is created, the adverse culturing condition and technical maloperation are reduced or eliminated. The survival rate of the breeding and young abalonesincrease about 28.9%-31.2%, the survival rate of the grown abalones is high up to 85%-90%.
通过挑选经济性状好的台湾九孔鲍和人工选育的九孔鲍亲体进行繁殖,避免近亲繁殖,选优除劣,达到正本清源的目的;采用正确的繁殖技术,获得优良的受精卵和幼虫,通过对幼虫进一步选优和培育,使附板后的幼鲍成活率及抗病力得到明显提高;为九孔鲍的苗种和亲本培育创造良好的养殖生态条件,减少和消除了不利的养殖环境和操作技术,达到品种复壮的目的;阐述了野生鲍、复壮鲍、退化鲍三个不同类群的免疫机能具有显著的差异,复壮后的九孔鲍,其免疫机能基本达到了野生鲍的水平;人工育苗和幼鲍的成活率提高了28.9%-31.2%;成鲍的养殖成活率高达85%-90%以上。
