| 摘 要： | 海洋鱼类食物网是海洋生态学基础理论研究之一,从多种海洋鱼类食性类型的综合分析,阐明食物网营养级的能流途径,为改造海洋生态系统,减少食物链的环数而提高水域生产力。因此,深入研究海洋鱼类食物网,对于合理利用海洋渔业资源具有一定的实践意义。近年来,国外在河口红树林群落,以残屑(detritus)为基础的食物网研究已有报道1];对河口游泳动物食物网也发表过综合论述2]。

| Abstract: | The pressnt paper is based upon the analysis of food habits of fishcs in Minnon-Taiwanchiantan fishing ground.There are 66 species of the marine food fishes of which 1,978 digestive-tract contents were examined.According to their dietary habits,these fishes may ba separated into 5 types:planktivorous fishes,benthophagous fishes,nektivorous fishes,planktivorous-benthophagous fishes and benthophagous-nektivorous fishes.The morphological structures of digestive organs are generally correlated with the types of their food habits.The consumers can be divided into 3 trophic levels,namely,(1) herbivores,comprisink also omnivores,(2) lower carnivores and middle carnivores,arid (3) higher carnivores,Most of these fishes belong to the lower carnivores.Principal pathways of energy flow in the food web of fish's hsve been summarized.In order to retain the maximum sustainable yield of the lower carnivorous fishes,such as Parargyrops edits,it is necessary to increas:the fishing intensity of the higher carnivorous elasmobranchs.Gastrosaccus hibii,Leptochela gracilis and Bregrraaceros macclellandii,the main food of the p0lzoic fishes,may possibly be used as a biological indicator for searching the fisiinL csnter,this is of considerable significance in practice. |
