ผลของไดอะตอม Thalassiosira spp. ต่ออัตรารอดตายและพัฒนาการของลูกปูม้า (Portunus pelagicus) วัยอ่อนระยะซูเอี้ย 1 ถึง 4 Thai Agricultural
Wasana Arkronrat; Vutthichai Oniam.
Effects of a diatom Thalassiosira spp. supplements on nursing of blue swimming crab (Portunuspelagicus) larvae from zoea I, II, III and IV stages. The results showed that average survival rates of crab larvae fed with Thalassiosira spp. + zooplankton (rotifers, Branchionus sp. and Artemia nauplii) were 93.33 ± 4.04, 79.66 ± 17.24, 72.66 ± 6.65 and 59.66 ± 2.08 %, respectively. The average duration of larval development from zoea I to IV stages was 8.3 ± 0.5 days. Their average survival rates and larval development were compared with those crab larvae fed with Chlorella sp. and Chaetoceros spp. + zooplankton. Results showed that average survival rates and larval development of crab in each treatment were not significant difference (P > 0.05). The results...

การเสริม Schizochytrium sp. ในอาหารต่อการเจริญเติบโต และอัตราการรอดตายในปลานิลรุ่น Thai Agricultural
Soudsada Saiyasaeng; Bundit Yuangsoi; Sutee Wongmaneeprateep.
Effects of Schizochytrium sp. on growth performance and survival rate of Nile tilapia, Oreochromis niloticus, juveniles were studied. Fish (initial weight 2.27-2.30 g) were fed with commercial pellet feed (32% crude protein) supplemented with Schizochytrium sp. at 0 (control group), 2.5, 5.0 and 7.5% for 8 weeks. The result showed that average weight gain of the 7.5, 5.0 and 2.5% Schizochytrium sp. supplemented were 37.84+1.227, 32.81+0.648 and 31.17+0.226 g, respectively, which were significantly different (P<0.05) from the control group (28.11+2.393 g). The Schizochytrium sp. supplemented fish had the average daily growth rate was significantly higher (P<0.05) than the control group but there was no statistically significant difference among...

ผลของการเสริม Schizochytrium sp. ในอาหารต่อการเจริญเติบโต และอัตรารอดตายของกุ้งก้ามกราม Thai Agricultural
Anousone Sisouvong; Chalor Limsuwan; Niti Chuchird; Sutee Wongmaneeprateep.
The effects of dietary Schizochytrium sp. supplementation on growth and survival rate of giant freshwater prawn (Macrobrachium rosenbergii) were studied. The prawns (approximate weight of 0.5 g/prawn) were fed with pelleted feed supplemented with Schizochytrium sp. at the levels of 0% (control group), 2.5%, 5.0%, 7.5% and 10.0%. Fifteen prawns were used for each treatment with the experiments being carried out in triplicate. Initial weight of the prawns was measured at the beginning of the experiment and after culturing for 50 days in suitable conditions, final weight, weight gain and survival rate of the prawns were recorded. The results showed that survival rates of the prawns were not significantly different regardless of levels of Schizochytrium sp....
