Fisheries ecology focuses on biology of fishery species, potential production, optimal stocking density and size, rational input of subsidy energy, and rational catch strategy, and so on.
前者是一门较为成熟的学科研究渔业对象的种群生态学渔产潜力最佳放流密度和规格以及科学的捕捞策略等。
It is suggested that insufficientdiet and size differences is a main reason causing the cannibalism among hybridsnakehead larvae; high stocking density can induce and stimulate the cannibalism .
因此，饵料缺乏和个体规格差异是导致杂交鳢苗种发生残食的根本原因，高密度养殖对残食的发生起着诱导和促进作用。
