捕捞产量

东海区海洋捕捞产量的时间序列分析研究

Study of time-serial analysis of marine capture yield in East China Sea region

由于近年持续的高强度开发，在海洋捕捞产量增长的同时，渔船单船产量和经济效益不断下降；

With the continuing rapid development in recent years , and the increasing amount of marine fishing , the economic benefits and yields of individual fishing vessel has been decreasing .

国外学者对中国提供的捕捞产量数据在国际刊物上公开提出疑问，造成不好的国际影响；国内的学者对这些数据具有同样质疑。

Foreign fishery scholars argued that the fish-ing production data from China in international journals , result in a bad international influence ; national academics also had similar questions on these data .

结果表明，海洋捕捞产量与定置网、拖网的产量的关联度高，与围网、钓具和流刺网的产量关联度低；

The result indicated that the correlativity was higher between marine fishing yield and the yields of fixed net and trawl , but was lower between marine fishing yield and the yields of seine , hook and gill net .

在上述背景下，政府相关部门给予了足够的重视，组织相关部门开始通过相对系统的分层抽样调查方法来评估渔业捕捞产量的试点工作。

In the above context , adequate attention has been paid by the relevant government departments , to organize some relevant academic institutions in order to carry out a pilot work on the estimation of marine fishing production by a sampling approach .

用灰色模型理论分析海洋捕捞产量，按渔具划分建立数值模型并预测浙江省捕捞业发展的特性与趋势，依据该数值模型所作的评估结果，提出了对浙江省海洋捕捞作业结构的调整意见。

The Characteristics and the trend of Zhejiang ocean fishery were forecasted by gray model which of fishing catch was worked out on fishing gears , and some views of adjusting Zhejiang ocean fishing structure were presented on the basis of these results in this paper .

联合国粮农组织（FoodandAgricultureOrganisation）的数据显示，2000年至2008年，渔业总产量增长了13%；这一增长是由养殖鱼产量贡献的，捕捞鱼产量则出现了下降。

Total fishery production has risen 13 per cent between 2000 and 2008 , according to data from the Food and Agriculture Organisation . That growth has come from farmed fish , and there has been a decrease in captured fish , according to the data .

1997年，中国海洋捕捞总产量1385.4万吨。

In 1997 the total output of China 's ocean fishing industry came to 13.854 million tons .

粮农组织说，捕捞渔业产量基本上没有可能显著超过上述水平。

There is little chance of any significant increases in catches beyond these levels , FAO says .

笔者以海洋捕捞年产量的预测为例，对指数平滑法中平滑指数α的取值问题进行了探讨，并提出了一种新的α取值方法。

In this paper , the choice of index is discussed in the index smooth method for forecasting the catch per year for marine fishing .

“因此，尽管我们所捕捞的鱼产量相同，但质量却不同，这一现象不能长时间维持下去，”他说。

" So while we are getting the same quantity of fish caught , we aren 't getting the same quality and this cannot be sustained over time ," he says .

为了持续发展福建省海洋捕捞业，必须实施海洋捕捞产量负增长的战略，并对现有的海洋捕捞结构进行调整。

In order to develop the marine capture fisheries continuously , the tactics of negative increment of fishing catches should be carried out and the present marine capture fisheries structure should be adjusted .

本文以福建省海洋捕捞业为例，分析了海洋捕捞业产量负增长及作业结构调整对渔业经济的影响，提出海洋捕捞结构调整后，发展海洋渔业经济的对策及思路。

The paper firstly analyzed the influence of negative increment of fishing catches and adjustment of marine capture fisheries on fisheries economic results , and then presented the countermeasure and thinking to develop the marine fishing economy after adjusting marine capture fisheries .

本文介绍了我国海洋捕捞强度的状况，包括海洋机动渔船数量及功率的变化、渔民数量、的变化及海洋捕捞产量的变化。

This thesis firstly introduces the condition of the marine fishing intensity which includes three changes : The first one is the number and power of motor-driven fishing boats , the second one is the number of fishermen and the last one is the marine capture production .
