| 池塘養殖中華絨螯蟹（Eriocheir sinensis）是當前的主要生產方式，為了解池養中華絨螯蟹形態名額參數，分別測定了中華絨螯蟹幼體和成體的頭胸甲長、頭胸甲寬、體高、體質量和各部位的質量及含水率，計算了肝胰腺指數和肌肉指數，旨在瞭解池養中華絨螯蟹形態名額及質量參數的關係。結果顯示，不同性別幼蟹頭胸甲長、頭胸甲寬、體高、肌肉指數無顯著差异（P>0.05），而體質量差异顯著（P<0.05）；不同性別成蟹各形態名額差异極顯著（P<0.01）；幼蟹的肝胰腺、肌肉及其他部分含水率差异極顯著，高於成蟹（P<0.01）；成蟹的肌肉指數和肝胰腺指數差异極顯著，高於幼蟹（P<0.01）。本研究分別建立了幼蟹體質量（Y1）與體高（X3）、成蟹體質量（Y2）與頭胸甲寬（X2）的回歸方程：Y1=12.067+16.416X3，Y2=268.423+62.078X2，幼蟹的決定係數高於成蟹。本研究可為中華絨螯蟹生態養殖中的產量估算和品質鑒定提供參攷。 |
| 英文摘要： |
| The Chinese mitten crab（Eriocheir sinensis）is an important freshwater crustacean cultured in China.It is popular with consumers because of its high nutritional value，pleasant smell，and taste.With increasing demand from the Chinese market，Chinese mitten crabs are now widely cultivated in ponds，lakes，and reservoirs.Pond culture of E. sinensis is the current main production method.To understand the parameters of morphological indicators of the Chinese mitten crab，some morphometrical traits，including carapace length（CL），carapace width（CW），carapace height（CH），and body weight（W）and moisture content were measured in E. sinensis cultured in ponds，and the hepatosomatic index（HSI）and muscle index（MI）were estimated to understand morphological attributes and quality parameters.The results showed no significant difference in CL，CW，body height，and MI in different sex groups of juvenile crabs（P>0.05），with significant differences in body weight in juvenile crabs（P<0.05）.There were highly significant differences by sex in the above indices for adult crabs（P<0.01）.Juvenile crabs had significantly higher HSI and MI than adult crab（P<0.01）.The regression equation for juvenile crab body weight（Y1），body weight of adult crabs（Y2）CW（X2），and CH（X3）were expressed as Y1=12.067+16.416X3，and Y2=268.423+62.078X2，a higher decision coefficient for juveniles than for adults.The findings provide a scientific basis for ecological breeding of Chinese mitten crabs in yield estimation and quality evaluation. |
