According to production statistics and resources monitoring data of light seine fishery on Minnan-Taiwan bank fishing ground(116°00′～119°30′E,22°00′～24°30′N)during 1987 to 2003 in Fujian, this paper studied and analyzed the status, developmental evolvement and utilization status of resources.
The average phytoplankton biomasses in 12 wintering ponds was 47.89 mg/L, comprosing 48.1% Chlorphyta, 19.3% Bacillariophyta, 13.2% Cryptophyta, 29.4% the others on Beidahu Fishery in Helan County, Ningxia.
According to the production database from March 2005 to January 2006 of Chinese trawler fishing vessels with the statistic format of 1°×1°,the plot is drawn by the software of Marine Explorer 4.0.Correlation of fishery distribution of jack mackerel versus SST is analyzed.
根据2005年3月至2006年1月我国大型拖网加工渔船在东南太平洋的生产资料,结合海表温数据,按经纬度1°×1°的空间单位进行分析,利用Marine Explorer 4.0软件作图,研究作业渔场CPUE分布与海表温的关系。
In 2000, the total production value of the main ocean industries was 4133.50 million yuan, 2.6% of Gross Domestic Product(GDP), and marine fishery value was 2084.34 million yuan, 50.43% of marine economic value of our country.
The thesis touches upon the importance of the betterment of the system to promote fishery technology and its positive contribution to the income increase and agriculture economy. Thus it illustrates the role of the fishery technology in the solution of "Sannong", concerning fishery technological demonstration, science and technology training, the service of industry and information and product sales.
Steady states of the dynamical system representing fishery are derived and their local, as well as global, stability is discussed.
Nonlinear Effects on Population Dynamics Related to Age Structure and Fishery Impact
The highest growth rate, primarily dependent on hydrological conditions, was observed in mussels from the Chupa Bay (Levin Navolok fishery), while the lowest rate was observed in mussels from the Umba region (Turii Cape, Murmansk Region).
Population Dynamic Instability of a Commercial Species Induced by Fishery
Results of computer simulations for a variant of fishery harvesting game are presented.
