Deepest CMarZ In a zooplankton trawl 5 km below the surface of the Sargasso Sea, Census experts from 14 nations caught drifting, often menacing looking, animals such as this amphipod, a small prawn-like crustacean, the supposed inspiration for the movie Alien.

CMarZ 来自14个国家的普查专家们在马尾藻海表层以下5公里处的一次浮游动物拖网中，捕获了这种漂浮的、相貌丑陋的端足类动物，它是一种小型的、类似对虾的甲壳类。

In the 1970s, for instance, West Coast trawlers were landing 11,000 tonnes of bocaccio a year. In 2001, just before the fishery was closed, the catch was 214 tonnes.

例如七十年代，在美国西海岸拖网渔船每年捕捞上岸11000吨菖鲉，到2001年，在此渔场被关闭前，捕捞量已降到214吨。

By central difference in time and space and boundary conditions, equilibrium equations of warp are transformed into the definite equations and solved by Newton\'s iteration.

通过在时间和空间上对拖网曳纲平衡方程组进行中心差分以及首尾边界条件的处理，将该方程组转换为定解代数方程组，并采用牛顿迭代法求解。

Indeed, trawling has been compared to clear-cutting trees.

事实上，拖网捕捞正可以比作成片的砍伐树木。

Advantages and disadvantages of each fishing vessel factors were evaluated and the relationship between yield and colligate score was established to provide better references for fishery administration.

评价出每艘渔船在4个公共因子上的优缺点，并探索渔获量与因子综合得分的关系，为渔业管理部门细化拖网渔船的管理提供参考。

Twin body trawl Two small bottom trawls joined with the inner wings removed and fished as a unit.

对拖网 连接到内部翼的二个小底拖网，作为一个单位移动和捕鱼。

The results showed that there were many coastal and epibenthile species, dominate fishes and crabs with significant monthly variation in composition, in the by-catch of shrimp beam trawls in waters surrounding Naozhou Island had. The average ratio of by-catch to shrimp was found to be 6.83:1 in weight and 2.5:1 in value, indicating that relatively high percentage of by-catch and less by-catch discards were the main problems in shrimp trawls.

结果表明：硇洲岛周围水域虾拖网副渔获种类多，主要为沿岸性底栖种类，组成结构存在明显的月变化，其中蟹类和鱼类是影响副渔获组成结构和月变化的优势类群；副渔获海上抛弃率很低，兼捕现象严重是现阶段虾拖网的主要问题，副渔获与目标虾类的平均重量比为6.8：1，平均产值比为2.5：1。

A modeling method to establish the mathematical model of single-boat mid-water trawl system is proposed, and visualization of the system is realized by using scene management software OpenGVS .

提出了一种单船中层拖网系统数学模型的建模方法，并通过场景管理软件OpenGVS实现了单船中层拖网作业过程的三维可视化。

Under the premise of reducing thelow-power single-trawlers,a number of single trawlers with larger power could workin deeper waters.

在减少小功率单拖网船的前提下，可以适度发展一部分较大功率单拖网船到水深较大海域生产。
