Yellowfin tuna ( Thunnus albacares) is a major target species of the tuna purse seine fishery in the Eastern Pacific Ocean. 黄鳍金枪鱼是东太平洋金枪鱼围网渔业中的主要渔获种类之一。
The Powell River, a tributary of the Tennessee, was devastated in1996 by spills of coal-mine sludge, which, among other things, drastically shrank the range of the threatened yellowfin madtom. 田纳西河支流之一的鲍威尔河曾在1996年由于煤矿淤泥泄漏遭污染,这一事故连同其他一些因素的影响,导致濒危物种黄鳍连尾的分布范围骤减。
Catch rate analysis of yellowfin tuna from longline fishery using generalized linear model in the Indian Ocean 利用广义线性模型分析印度洋黄鳍金枪鱼延绳钓渔获率
Atlantic Ocean catches consist mostly of yellowfin. 大西洋所渔获的也基本上是黄鳍金枪鱼。
Based on the catch data of yellowfin tuna captured by Chinese tuna longline fleet in the west-central Indian Ocean from January to June in 2003 and 2004, the basic biological characteristics of catch composition of yellowfin tuna captured were investigated. 根据2003-2004年1-6月印度洋中西部海域金枪鱼延绳钓所捕获的黄鳍金枪鱼数据,对其基本的生物学特征进行了研究。
THE CHARACTERISTICS OF FISHING GROUND OCEANOGRAPHY AND FISHERY BIOLOGY OF YELLOWFIN SOLE IN EASTERN BERING SEA A Study on the Relation. Between Fishery Resources, Fishing Production and Fisheries Administration 东白令海的刺黄盖鲽渔场海洋学与渔业生物学特征论渔业资源、捕捞生产和渔政管理的关系
It was found that the lowest activating salinity of each of spermatozoa of yellowfin bream, silver bream, black porgy and red seabream should be 8, 10,> 8,> 10 at least respectively. 对南海区4种鲷鱼精子的适盐性及其活力进行了比较,黄鳍鲷、平鲷、黑鲷和真鲷精子激活所需的最低盐度分别为8、10、>8、>10;
The catch weight was different in various sea areas, the proportion of skipjack tuna in the sea area east of 162 ° E was higher than that west of 162 ° E, while yellowfin tuna was contrary to skipjack tuna. 渔获物重量组成存在海域差异,在162°E以东海域鲣鱼比例高于以西海域,黄鳍金枪鱼则是在162°E以西海域的比例较高。
Longline fishery dominates the Tonga tuna fisheries. Albacore, yellowfin tuna, and bigeye tuna are the main catch species. 汤加金枪鱼渔业以延绳钓渔业为主,主要捕捞鱼种是长鳍、黄鳍和大目三种金枪鱼。
Relationship between vertical distribution of yellowfin tunas '( thunnus albacares) and the concerned environmental factors in the Central Atlantic Ocean 大西洋中部黄鳍金枪鱼(Thunnusalbacares)的垂直分布与有关环境因子的关系
The results showed that the distribution of yellowfin tuna longline fishing-grounds are mainly located in the tropical areas, which are between 20 ° N and 20 ° S. 结果表明:太平洋延绳钓黄鳍金枪鱼渔场主要分布在20°N&20°S之间的热带太平洋海域,具纬向分布特征。
The barycenter of fishing ground for yellowfin tuna were different in El Nino and La Nina condition from the other year. 黄鳍金枪鱼各月的作业渔场重心与其他年份差异较大的年份几乎都在厄尔尼诺和拉尼娜发生的年份。
The difference of wild and cultivated yellowfin black porgy was that the numbers of mucous cells in the wild fish were more than the cultivated fish in the same part of digestive tract. 野生与养殖黄鳍鲷粘液细胞的区别在于消化道的相同部位,养殖鱼比野生鱼粘液细胞数量更多。
The major histological differences between wild and cultivated yellowfin black porgy were that there were more goblet cells in the same part of digestive tract in cultivated fish than in wild fish, while the muscular coat was thicker in wild fish than in cultivated fish. 野生与养殖黄鳍鲷组织学的区别在于,消化道相同部位养殖鱼的杯状细胞多于野生鱼,野生鱼的肌层厚度大于养殖鱼。
