我国渔业的海洋环境调查,多年来,基本遵循《海洋调查暂行规范》的规定进行。所使用的仪器及其技术标准接近于该《规范》要求。中国农林科学院1974年7月所编《海洋渔业资源调查的几项技术标准(试行)》与青岛海洋水产研究所编的《水产资源调查手册》中均反映了这一情况。从各海区调查现状看,统一的仪器与方法促进了科研的发展,反过来,科研的进展又对仪器、方法本身提出了新的要求。许多渔业专题的调查中,除沿用原有方法外,又各自提出一些新的规定,许多观测中也使用了一些新的仪器。这是新情况,也是发展的必然。渔业的海洋环境调查中,进行最多的,要算温、盐度的观测。鱼类对环境海水温、盐度的生理适应要求,形成了这二项要素观测的重要性与必要性。另外,温、盐度资料提供分析
The marine environment survey of China’s fisheries has basically followed the provisions of the Interim Provisions on Marine Surveys for many years. The instruments used and their technical standards are close to the Code. This situation was reflected in the “Technical Standards for the Investigation of Marine Fishery Resources” (Trial) compiled by the Chinese Academy of Agriculture and Forestry in July 1974 and the “Manual of Fishery Resources Surveys” compiled by the Qingdao Marine Fisheries Research Institute. Judging from the status quo of the sea survey, the unified instruments and methods have promoted the development of scientific research. In turn, the progress of scientific research has put forward new requirements on the instruments and methods themselves. In many surveys of fishing specialties, besides the original methods, some new regulations have been put forward respectively and many new instruments have also been used in many observations. This is a new situation and an inevitable development. In the marine environment survey of fisheries, the most extensive one is the observation of temperature and salinity. The physiological adaptations of fish to environmental sea water temperature and salinity have formed the importance and necessity of the observation of these two elements. In addition, temperature and salinity data provide analysis
