Short-term starvation or fasting has known to allow the minimum feed usage without inhibiting biota growth, also improves digestive function, reduces the amount of water-soluble nutrient metabolites, and reduces operational costs. Spiny lobster (P. homarus) measuring 50.0 ± 10.0 g was reared for 6 weeks in floating net cages. Lobsters were fasted at intervals of 1 fasting day/1 day of feeding, 1 fasting day/2 days of feeding, and fed daily. Survival, growth, and feed efficiency of spiny lobster (P. homarus) were analyzed. Higher growth rate and energy retention were found in spiny lobster (P. homarus) reared with short-term fasting system. Lower FCR also found in the same rearing system.

Penja fish belong to the Goobidae family, which has a habit of migrating from the sea to the river. Penja fish species have not been widely published or in the Gen bank. The objective of this study was to analyze the Penja fish species found in the Budong-Budong river, West Sulawesi, Indonesia. The method used was a measurement of fish morphology and analysis of mitochondrial cytochrome oxidase I (COI) using a species barcode (~700). Samples were taken from the catch of fishermen at the mouth of the Budong-Budong river. The result of morphological measurements obtained an average total length of 25-38 mm, standard length 22-35 mm, head length 2-5 mm, tail length 3-5 mm, pelvic fins 0.5-2 mm, pectoral fins 1-3 mm, dorsal fins 1-3 mm and anal fin 0.1-1 and body width 3-6 mm. Electrophoretic analysis on Penja fish samples showed that the DNA between P1 and P2 samples was not much different and has very small genetic variation in 696 bp fragment length. The analysis on the Basic Local Alignment Search Tool (BLAST) showed the identity percentage reached 99.85%. The Penja fish identified in the Budong-Budong river is of the family Gobiidae, genus Sicyopterus with the species name Sicyopterus pugnans, which is classified as post larva.

Salinity gives impact to shrimp live, immunity and health. Stress from salinity shock will reduce shrimp health and production because of pathogen attack. White faeces syndrome (WFS) is a shrimp disease which frequently occured in an intensive farm. Fighting against WFS has been done with several methods, among other things by using ink extract as metabolite product of squid (Loligo sp.) because of its antibacterial content. To solve the problem, combination of ink extract with salinity treatments to CypA gene expression THC, DHC and digestibility of vaname shrimp (L. vannamei) was investigated. The best treatment using squid ink extract was 27 ppt salinity for vaname shrimp (L. vannamei) against WFS, because it gave the highest SR (85.73%), increased protease until 378 × 10 −3 U/ml, amylase until 4.029 × 10 −3 unit/ml and lipase until 3.613 × 10 −3 unit/ml. and also non-specific immune, i.e. THC 11.89 × 10 6 cells/ml and DHC (hyaline was 39.09%, granular cell was 21.43% and semi-granular cell was 47.74%), while mutation (>1%) was happened in CypA gene.
