In this study, we examined the effect of different dietary inclusion levels soy lecithin on growth, feed utilization, digestive enzyme activity, whole body fatty acid profile, deformity and survival milkfish (Chanos chanos) larvae, through a six-week feeding experiment. During trial, five isonitrogenous isoenergetic (~580 g kg−1 protein, 120 lipid 20.5 MJ kg−1) practical larval diets with (0, 17.5, 35, 52.5 70 Kg−1 in place fish oil) were fed to triplicate groups 18 days post-hatch three...
C-Phycocyanin (CPC) was extracted from Arthrospira sp. and isolated an estuarine ecosystem in southern India. A 45-day feeding trial conducted to unravel the effect of dietary CPC Penaeus vannamei. Seven iso-nitrogenous iso-energetic experimental diets were prepared with different levels at 0 (CPC0), 50 (CPC50), 100 (CPC100), 200 (CPC200), 400 (CPC400), 800 (CPC800) 1600 (CPC1600) mg per kg diet. The results revealed that survival percentages CPC200, CPC400, CPC800 CPC1600 significantly (p <...
A sixty-day feeding trial was conducted to determine the ascorbic acid (AA) requirement for growth of striped catfish, Pangasianodon hypophthalmus juveniles. Seven iso-nitrogenous and iso-energetic (370 g protein per kg 19.6 MJ/kg) purified diets were prepared with different levels such as control (0), T1 (17.5), T2 (35), T3 (70), T4 (175), T5 (350) T6 (700) mg (L-ascorbyl-2-polyphosphate) equivalent diet. Fish a mean body weight 3.2–3.4 stocked (fifteen fish tank) in triplicates following...
Silver moony, Monodactylus argenteus (Linnaeus, 1758), belonging to the family Monodactylidae, has high significance in ornamental fish industry. The present study provides details of captive broodstock maturation, induced breeding and larval rearing this species for first time. Juveniles were collected from wild raised adults net cages. Female with oocyte diameter =500 µm oozing males selected sex ratio 1:2 (female: male) spawn using a single dose LHRHa. Spontaneous spawning fertilization...
Total phenol, flavonoid, carotenoid and antioxidant activity of four green macroalgae (Halimeda tuna, Halimeda macroloba, Enteromorpha sp. Acetabularia acetabulum) collected from South Andaman coast were analysed in this study.The results revealed that methanol extract sp.showed maximum phenolic, flavonoid content 5.72±0.13mg GAE/g, 21.15±1.05mg RE/g 47.78±0.46µg/g respectively.All the species exhibited activities dose dependent manner among which sp.demonstrated greater potential.A....
Vitamin E is one of the most important vitamins in aquatic animal breeding, larval growth, and development. It also considered to be a functional feed addtitive for its antioxidant immunity-improvement role resulting better survival growth during early life stages. However, vitamin diet milkfish larvae has not been studied detail. Moreover, optimal requirement improved stages yet ascertained. A 45-day feeding experiment was conducted elucidate effect dietary (alpha tocopherol)...
The present study was aimed to analyse the nutritional composition and antibacterial activity of selected green macroalgae from Andaman Islands. Proximate estimated for four species namely, Halimeda macroloba, tuna, Enteromorpha sp. Acetabularia acetabulum. Methanol Dimethyl Sulphoxide (DMSO) dissolved extracts these were tested against human fish pathogens such as Staphylococcus aureus, Aeromonas hydrophila, Escherichia coli Streptococcus pneumoniae. results revealed that maximum protein...
Andaman and Nicobar Islands are pristine in nature blessed with a variety of species diversity general as well aquatic resources specific. The three facets environment namely, freshwater, brackishwater marine not fully tapped to the potential therefore have further scope for improvement. At present, only freshwater carp farming is being practiced Bay while aquaculture mariculture identified areas development. Diseases major constraints development sector. present study reviews work carried...
Amino acid (AA) and fatty (FA) composition of the fertilised eggs different larval stages (at 0, 3, 6, 9, 12, 15 and21 days post-hatch, dph) Chanos chanos was investigated. The total indispensable amino acids (IAA) contributed to55.62% AA in egg which reduced to 52.54% on 6 dph. profile C. found be rich invaline (7.99%), leucine (7.51%) lysine (6.98%) poor histidine (2.36%) methionine (2.47%), indicating a highvaline, requirement. docosahexaenoic (DHA) content recorded for egg, newly hatched...
The present study was intended to screen the wild shrimps of Andaman and Nicobar Islands (ANI) against infectious diseases. A total 175 shrimp samples (35 pools) consisting Fenneropenaeus indicus, Penaeus monodon, merguiensis Metapenaeus monoceros were collected from different landing centres across ANI. Out 35 pools analysed by polymerase chain reaction (PCR), a 10 monodon Betapur (1 pool), Lohabarrack (4 Campbell Bay (5 found positive for Infectious Hypodermal Hematopoietic Necrosis Virus...
