Abstract
The objective of the present study was to evaluate the feed digestion of tiger grouper (Epinephelus fuscoguttatus) juvenile in stomach and intestine with different times. The experiment was conducted in Brackish Water Aquaculture Research Station at Ujong Batee, Aceh, Indonesia in May 2011. The observation was done at every 2 hours interval for 12 hours. The tiger grouper juveniles were obtained from the hatchery of Brackish Water Aquaculture Research Station. The samples were fed with the commercial pelleted feed of Otohime EP2®. The fish samples were taken randomly and sacrificed to obtain their stomach and intestine contents for proximate analysis of nutritional contents. The results showed that the digestion of proteins in the stomach was slower than in the intestine, while the optimum time of digestion for protein in the intestine was 10 hours post feeding, while 12 hours in the stomach. In addition, the optimum time of lipid digestion in the intestine was eight hours compared to 10 hours in the stomach. The carbohydrate components were not digested effectively by the tiger grouper juvenile.

Attempts to increase the growth rhythm of juvenile Northern pike (Esox lucius, L.) by adding enzyme based ingredients into dry feed
Northern pike’s rearing in recirculation systems is limited because of increasing FCR together with size of fish. The reason is apparently connected to the disability of pike to secrete sufficient digestive enzymes to pr...
PCR detection of white spot syndrome virus (WSSV) from farmed Pacific white shrimp (Litopenaeus vannamei) in selected sites of the Philippine
Great losses caused by white spot syndrome virus (WSSV) in shrimp culture have been attributed to poor screening procedures in farms and the lack of sufficient access to specific pathogen free brood stock. Thus, early...
Research regarding the evolution of corporal masses and feed conversion on sterlet (Acipenser ruthenus) juvenile raised in recirculating system
The research was performed on 3375 specimens of sterlet juveniles (Acipenser ruthenus) maintained in five square pools (1.5 x 1.5 x 0.7 m; V=1.125 m3) and in a round pool (Ø=3 m; H=1 m; V=5.63 m3). Water temperature vari...
