PRELIMINARY STUDY ON SEPIA ESCULENTA OOSPERM HATCHING AND EFFECTS OF DIFFERENT ADHESION SUBSTRATES

ZHAO Houjun 1,2, WEI Bangfu 3, Hu Ming 3, DU Zhenxi 3, WU Tingshan 3, WANG Maoqin 3, ZHANG Xiumei 1, WEI Liuzhi 1 (1. Fishery College, Ocean University of China, Qingdao 266003; 2. Shandong Fishery Technical Extension Station, Jinan 250013; 3. Rizhao Fishery Technical Extension Station, Rizhao, 276800)  
An experiment on the hatching of Sepia esculenta oosperms from lanshan coastal waters of Rizhao was conducted under the laboratory conditions. The hatching rate of Sepia esculenta oosperms was about 79.3% and the overall morphology of the hatchlings was similar to that of the adults. The average values of mantle length and body weight were 5.33mm and 70mg, respectively. The results on the effects of Chengliu (Tamarix chinensis), Huanghuahao (Artemisia annua), Difucao (Kochia scoparia) and Zhumiao (bamboo branch) showed that their average adhesion rates were 74.0%, 71.2%, 31.9% and 20.2% respectively, and the average values of proportion of egg number above 500 were 79.7%,72.8%, 10.5% and 0 respectively. Therefore, Chengliu and Huanghuahao may be selected to be adhesion substrates for Sepia esculenta oosperms for its enhancement.
