蓝鳃太阳鱼的生物学及池塘养殖技木研究

【摘要】 蓝鳃太阳鱼(Lepomis、macrochirus)作为一种养殖前景广阔的温水性鱼类,在我国东北地区进行养殖实验尚未见报道,更没有成规模养殖。通过对蓝鳃太阳鱼标本的观察与解剖,根据蓝鳃太阳鱼的有关生物学特性.表明其在东北地区进行养殖具有一定的可行性。我们通过蓝鳃太阳鱼在哈尔滨市太平区民主乡新立渔场的养殖试验状况,探讨了蓝鳃太阳鱼在高寒地区的生长成活状况。实验结果表明,在东北地区蓝鳃太阳鱼养殖成活率较为理想(单养达85％,混养达67％),能成功越冬,在6-8月份生长状况良好,而且,其在混养状态下要比单养状态下的生长速度快。本实验对养殖条件要求较为简单,易于推广。所以本文的研究为蓝鳃太阳鱼在东北地区的推广养殖提供了基础性资料。更多还原

【Abstract】 Blucgill Sunfish(Lepomis Macrochius), as a warm -water fish with wide breeding prospect, has never been experimented in northeast region of China, let alone large scale breeding. By observing and anatomizing a certain number sample of bluegill sunfish, at the same time, combining some existed literature data, we summarizes the biology characteristics of bluegill sunfish. Through a series of elementary collection of experiment data, we discussed the situations of bluegill sunfish growing and breeding in northeast regions. It was showed that the survival ration of bluegill sunfish was ideal (alone85%, mixture 67% ), and it can succeed getting through winter. Bluegill sunfish took on great growth between June and August, and it grew better in the breeding aquatics than cultured alone. Since the experiment condition is extensive, our research can make a foundation for the intensive breeding.更多还原
