对绒螯近方蟹(Hemigrapsuspenicillatus)的生态习性和繁殖生物学进行了初步的调查和实验研究。雌性、雄性甲宽与体重的关系分别为W♀=0.6056×L2.9806(n=132,r=0.96),W♂=0.5893×L3.1215(n=50,r=0.97)。抱卵量与甲宽的关系为Q=865.82L-7275(r=0.97)。幼体发育分为5期状幼体和1期大眼幼体。胚胎、状幼体和大眼幼体的发育积温分别为219.4℃,226.35℃,49.3℃(以12℃为生物学零度)。
A preliminary investigation and experimental study on the ecological habits and breeding biology of Hemigrapsus penicillatus were conducted. The relationship between female and male Jiajuan and body weight were W ♀ = 0.6056 × L2.9806 (n = 132, r = 0.96) and W♂ = 0.5893 × L3.1215 (n = 50, r = 0.97). The relationship between the number of eggs and nail width is Q = 865.82L-7275 (r = 0.97). The development of larvae is divided into 5 stages of juvenile larvae and 1 large-eyed juveniles. The accumulated accumulated temperatures of embryos, galls and big eyes were 219.4 ℃, 226.35 ℃ and 49.3 ℃ respectively (biological zero degree at 12 ℃).
