对虾人工配合饵料颗粒规格的探讨
徐尔栋1
中国科学院海洋研究所
摘要:
本文对对虾饵料的颗粒长度进行了研究和测定。结果表明,饵料颗粒的长度是不均匀的,颗粒长度为3.7—0.3cm(碎粒)。文中还根据对虾饱食量的大小计算了对虾对均匀和不均匀的颗粒饵料的理论耗损率。基于此,作者建议在制订人工配合饵料的规格时,不仅要规定颗粒饵料的直径,而且还应明确颗粒饵料的长度和标明每种颗粒饵料的规格适合投喂的对虾体重等级。

A STUDY ON THE SIZE OF GRANULAR FEEDS OF PRAWN
Abstract:
In this article, length of granular feeds of the prawn is determined. The result indicates that the length of broken granules is irregular from 3.7cm to 0.3cm. This article also compares the percentage consumption of granules feeds of regular length and irregular length. It suggests the size of granular feeds should be that as can be taken within the stomagastric full intake of prawn.
