捕捞鱿鱼的作业方式,以往主要有群众手钓作业和拖网兼捕作业两种。而群众手钓作业方式比较落后,多数单线单钩,劳动强度大,产量低。我校根据农林部的科研项目,自一九七四年以来,先后对日制和我校仿制的鱿鱼自动钓机进行了反复试验,通过几年来试验结果比较,今年试钓的产量比往年最高产量高2—3倍,七四年日制钓机平均每台钓机每小时钓3.7尾,而金年达9.6尾/小时。往年我们是根据群众手钓的传统渔场渔汛在浅海区试钓产卵群体,而这种群体主要是栖息于底层行产卵繁殖,很少活动到水域的中上层来,所以适宜于手钓作业,这种作业钓钩是
Squid fishing operations, in the past there are mainly people hand fishing operations and trawling operations two. However, the fishing operation by the masses is lagging behind. Most single-hooks have large labor intensity and low output. According to the research projects of the Ministry of Agriculture and Forestry, our school has conducted repeated tests on day-time and squid automatic fishing machines imitated by our school since 1974. According to the comparison of test results over the past few years, the output of trial fishing this year is the highest compared with previous years The output is 2-3 times higher. In 1970, the average daily fishing tackle of DiaoYan catchs 3.7 fish per hour, while the golden year reaches 9.6 fish per hour. In previous years, we tried to fish spawning groups in the shallow sea area according to the fishing festivals of the traditional fishing grounds caught by the masses. However, this group mainly spawned in the bottom row to spawn and rarely move to the middle and upper reaches of the waters. Therefore, it is suitable for hand-fishing operations This job hook is
