Effects of substrate type on succession of periphyton and in-termediate seedling culture of sea cucumber,Apostichopus ja-ponius Selenka, in net cages set in an earthen pond
摘要
Abstract
Afield experiment was conducted in nine net cages of 2 m3 (2 m×1 m×1 m) set in an earthen pond during the intermediate seedling culture period of the sea cucumber,Apostichopus japonicusSelenka. The experiment in-vestigated the occurrence and succession of periphyton on the surface of three different substrate types (i.e., four different substrate materials) of curvimurate net (CU), ground cage [cage net (CN) & cage plate (CP)], and nylon mesh (NM). Moreover, the effects of substrate type on the growth, survival rate, and yield ofA. japonicus were examined simultaneously. The results indicated a similar succession process in periphyton among different sub-strates. The dry weight (DW) and ash free dry weight (AFDW) of periphyton on CP were significantly higher than that on three other materials (P<0.05), while no significant differences were observed among other substrates (P>0.05). The contents of chlorophyllaon the surfaces of the four substrates in descending order were CU>CP>NM>CN, and significant differences among the four substrates were found. After 12 weeks of seedling culture, the yield of the sea cucumber was significantly higher in the net cages with CU than in those with a ground cage (P<0.05), and the survival rate of the sea cucumber in was significantly higher in the net cages with CU than in other net cages (P<0.05). After 17 weeks of seedling culture, the yield of sea cucumbers was significantly higher in net cages with CU than in the other net cages (P<0.05). The survival rate and special growth rate (SGR) of sea cu-cumbers was significantly higher in net cages with CU than in those with NM (P<0.05); however, no significant difference was observed between the ground cage and two others (P>0.05). The present results demonstrate that substrate type has a significant influence on yield, survival rate, and growth ofA. japonicus during the intermediate culture period. On the basis of comprehensive results analysis of the present study, the substrate CU should be recommended as the better one for the intermediate culture of sea cucumber.关键词
