摘要
本文用１８个１４．３ｍ￣３的围隔组成的围隔群，以鲤为材料，研究了水库对投饵网箱养鱼的负荷力。实验中观测了水温、透明度、ｐＨ值、溶氧、化学耗氧量、生化需氧量与非离子氨等环境因素的变化。结束时将这些变化与我国渔业水质标准相比较，查明该负荷力约为３０００ｋｇ·ｈａ￣（－１），建议增加２５－３５％的安全储备，以最大载鱼量１８００－２３００ｋｇ·ｈａ￣（－１）作为推荐值。
Carrying capacity of reservoirs for feeding cage-culture of fish was estimated using 18 experimental enclosures,each 14.3m￣3 in volume and stocked with common carp. The car-rying capacity was defined as the maximum possible density of cultured fish in the reservoir that does not result in violation of the“Water Quality Standard for Fisheries”(GB 11607-89).The experiment was carried out at Dongzhou Reservoir,Xintai City,Shandong Province during June 15-July 18,1990.The variations in the environmental factors,including water temperature,transparency,pH,dissolved oxygen,COD,BOD and UIA were monitored dur-ing the experiment.The carrying capacity was estimated to be about 30O0 kg· ha￣(-1).The authors suggestthat a safty parameter of 25-35% should be used,and therefore the maximum allowable den-sity of clutured fish should be 1800-2300 kg· ha￣(-1), as recommended to fish fanners.
