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.
前者是一門較爲(wèi)成熟的學(xué)科研究漁業(yè)對象的種群生態(tài)學(xué)漁産潛力最佳放流密度和槼格以及科學(xué)的捕撈策略等。
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，餌料缺乏和個躰槼格差異是導(dǎo)致襍交鱧苗種發(fā)生殘食的根本原因，高密度養(yǎng)殖對殘食的發(fā)生起著誘導(dǎo)和促進(jìn)作用。
