众所周知,鱼类的放养密度和它相应的强化措施(施肥、饵料和其他),对池塘的化学状况,鱼类的生长,给予极重要的影响,那么,对池塘鱼产量也给予很大的影响(В、А、莫夫契,1948;М、Ъ维尔特姆和Г、И、斯别特,1960;С、М、巴切克,Н、Н、哈里多岁娃,О、А葛罗吉茨卡娅,1974;С、М、巴切克,В、С、布罗亚尼,1974)。我们研究的目的,是弄清楚鱼类放养密度对池塘水文化学的影响,池底沉积物的形成,以及这些因素在鱼类生长和鱼产量上的影响。研究工作于1972年,在《尼夫卡》试验场的成鱼池进行。按机械组成这些池塘的底部沉
It is well-known that the stocking density of fish and its corresponding enhancement measures (fertilizers, bait and others) have an extremely important influence on the chemical status of ponds and on the growth of fish, which in turn have a significant impact on pond fish production (В, А, Moffat 1948; М, Ъ Wiltrt and Г, И, Štebbe, 1960; С, М, Basček, Н, Н, Khalifa, О, А Gros Gateskaya, 1974; С, М, Baccek, В, С, Broynei, 1974). The purpose of our research is to understand the effects of fish stocking density on pond hydrology, sediment deposition at the bottom of the pond, and the effects of these factors on fish growth and fish production. Research work was conducted in 1972 at the fish pond of the “Nifka” test site. The bottom of these ponds is made up mechanically
