摘要
Abstract
The relationships between unit cost and unit catch with unit value were analyzed based on the survey of 90 cruises of 10 pair trawlers with power of 382.2 kW in Weihai of Shandong province after reducing system errors.The conclusions were as follows.There was a certain level of profit to the sample trawlers in 7months of the year 2012 except March and April.The best linear relationship between unit cost and unit value reached 1.9134 in February.And the best linear relationship between unit catch and unit value reached 8.823 in September.According to this analysis,it was recommended that the pair trawlers with power of 382.2 kW should stop operation in April to reduce losses.关键词
