【摘要】 口虾蛄形态参数间的关系是合理开发口虾蛄资源的重要依据，且为进行养殖和实验生态研究提供了基础理论资料。本文对６７４尾（体长５．２０－１５．４０ｃｍ）口虾蛄的全长、体长、头胸甲长、腹宽、体重等进行了测定分析。着重研究了体重与体长和头胸甲长与体长的关系，分别得关系式为：雌、雄（ｒ＝０．９７２９）和雌Ｉ＝雄。同时还得出体长７．０－８．０ｃｍ是其体型趋于稳定的转折点，雌雄口虾蛄形态差异不显著。对肥满度和增重率的周年变化分析结果，３月份肥满度最高，８月份最低。综合考虑认为每年的１１－１２月份是合理捕捞期，体长１１ｃｍ左右为最适捕捞规格。更多还原

【Abstract】 In th is paper the who le l ength,body length , carapace length,abdomen width and body weight, etc,of Oratosquilla oratorla have been determined in 674 indexes(body length 5.20-15.40 cm),and the date has been treated with computer for fema les and rna les,respect ively,The relations between bedy we ight and body l ength , carapace length andbdy length are ma inly calcul-ated. The results are: W(♀)=0.0169L2.8935(r=0.9778),W(♂)=0.0125L3.0241(r=0.9729) and(♀)=1. 1073×10-3+0.2383L(r=0.9999),I(♂)=3.1031×10-3 +0.2385L(r=0.9967)·The change of other m0rphologieal parameters is also studied·The body length of 7.0-8. 0 cm is a turning point of steady body form and the morphological difference between females and males is not outstanding。The change o f ful lness index and body weight increase is 0beerved all year round,too.It was found that the highest and the lowest fullness index occurred in March and Auqust,respectively,On the basis of this study, we cons idered th e durat ion from November to December the reasonable fishing season, and body length of ab0ut 11. 0 cm the most suitable sizes for catch.更多还原
