    Project Name: All India Network Project on Fish Health

    • Oreochromis niloticus juveniles (7.78±0.50 g) were found to be more susceptible to hydrophila than O. niloticus fries (0.50±0.13 g) at temperatures in the range of 17-20°C.
    • Significantly high mortalities (36.67%) were observed during winter season (17-20°C) in skin wounded, challenged and untreated group compared with the mortalities (23.80%) during summer season (30°C) in skin wounded, challenged and untreated group.
    • About 35% or more mortality was recorded in winter than summer during challenge experiments.
    • Oxytetracycline (OTC) was effective in controlling the Aeromonas hydrophila infection in niloticus when used with feed and as bath/dip treatment.
    • OTC medicated feed treatment was more effective than bath/dip treatment during challenge experiments.
    • Skin wounding followed by immersion resulted in high levels of mortality in niloticus. The mortality in skin wounding followed by immersion mode was 6.75 and 10.8 fold higher than the intraperitoneal and intramuscular injection routes, respectively.
    • The kidney tissues of Oreochromis niloticus intramuscularly challenged with Aeromonas hydrophila on 10th day post-feeding with OTC fed (2 g OTC/kg feed @ 2% b/w) exhibited glomerulopathy with mild pathological changes, slight necrosis, inflammation, degeneration and thickening of nephritic tubules; While in 4 g OTC/kg feed @ 2% b/w fish, the kidney tissues, on 10th day post-feeding exhibited glomerulus with thin epithelial layer, inflammation and improved organization of nephritic tubules. No necrotic changes were noticed.
    • Residues of OTC have been detected in bath treated niloticus fries for up to 10-15 days post-treatment by ELISA based OTC kit.
    • The residue levels in niloticus samples increased as a function of dosage levels, except when the fish were subjected to 21 days of withdrawal period.
    • Cultured Litopenaeus vannamei (22%) was found to be infected with WSV (Asymptomatic). No infection due to IHHNV, HPV, AHPND, Enterocytozoon hepatopenaei (EHP), running mortality syndrome, etc were recorded during the reporting period.
    • White faecal cast problem was noted in Litopenaeus vannamei in few surveyed farms.
    • Exotic diseases like Streptococcus agalactiae infection, Piaractus brachypomus (Pacu) fry mortality syndrome of unknown etiology, brain myxoboliasis were noted in Oreochromis niloticus, Piaractus brachypomus and Clarias gariepinus, respectively cultured in West Bengal.
    • Conducted six awareness programs/meetings on BMPs in aquaculture in 6 districts, and five one day training programs for stakeholders on principles and practice of BMPs were conducted during the reporting period. Farm advisory was also provided to the farmers on disease, disease management and prophylactic and control measures
    • Collected 60 farm production loss details in West Bengal

    Project Name: NATP on Shrimp and fish health management

    Twenty three disease conditions – 5 infectious diseases and 18 non-infectious- were observed in the cultured shrimp on 269 farm visits between 2000 and 2004. In grow-out ponds, the luminous bacterial counts (LBC) were higher (log 2.91±0.57/ml) between DOC 30 and 60. The LBCs increased up to DOC 60 and decreased thereafter both in water and sediment samples. Histopathological observations on diseased shrimp revealed predominance of WSSV infection and multiple diseased conditions. HPV infection was noticed in few infected shrimp. Luminous bacteria Vibrio harveyi induced septicemic hepatopancreatitis was noticed in semi-intensive grown Penaeus monodon. Protozoan ectoparasites such as Acineta, Epistylis, Vorticella and Zoothamnium were found in penaeid shrimp of bheries, of which Zoothamnium was the most common. Microsporidian infected the muscle, gonad, hepatopancreas and to a lesser extent on gill and gut epithelial layer of P. monodon from bheries. Antagonistic marine bacteria such as Alteromonas sp, Bacillus sp and V. harveyi were found to have vibriostatic activity.

    Project Name: ICAR Ad-hoc Scheme: Use of probiotics in freshwater aquariculture

    An indigenous gut bacterium, Lactobacillus sp P21, isolated from mrigal, Cirrhinus mrigala was used as a probiotic strain on the basis of its wide spectrum of action. The probiotic bacterium was administered through feed, water and live fish-food organisms – Tubifex and Artemia nauplii (Bioencapsulation) and the efficacy assessed. The Lactobacillus sp P21 was able to improve the growth and survival of goldfish, Carassius auratus and sword tail, Xiphophorus helleri, and confer protection against pathogens when applied through water and/or bioencapsulation in live fish foods. The probiotic strain competitively excluded pathogens by the production of antibacterial substance and improved the nutritional efficiency. The probiotic strain resisted fish bile and low pH, colonized in the gut, formed biofilm and/or adhered to different substrates and fulfilled the major requirements of being an effective probiotic. The incorporation of probiotic in feed favourably influenced the reproductive performance of X. helleri in terms of high fecundity, high fry survival and reduction in fry mortality and deformity.

    Project Name: ICAR Ad-hoc scheme on Design and development of responsible trawl for pomfret fishery along the northeast coast of India

    In the Northeast coast, 65 % and 35 % of the trawlers were engaged in the fishing of demersal and pelagic fishes, respectively. The pomfret catch composition was 17-19% in trawlers. Among the pomfrets, Pampus argenteus (silver pomfret) contributed the major share (89 %), followed by Parastromateus niger (black pomfret, 6%) and Pampus chinensis (white or Chinese pomfret, 5 %). The maximum catch was contributed by 50-100 mm length group (25 %) followed by 100-150 mm (16 %). The pomfret catch was significantly increased in the newly developed semi-pelagic pomfret trawl (40-50%) compared to control trawl (14-15%). The selectivity curves of silver pomfret for mesh size 40 mm, 60 mm and 80 mm of square mesh codend coincided with each other at higher length groups. The selection curve of pomfret for 40 mm indicated that square mesh codend of 40 mm is required either 30 or 40 % for notable escapement. Considering length at 50 % maturity of pomfret (14 cm for female), the actual legal minimum mesh size opening (80 mm) is adequate because l50 (14.07 cm) is greater than Lm. With 80 mm mesh opening, it is possible protect the reproductive potential of female pomfret. The study provided selectivity Master Curve, which would help determine retention lengths for any mesh size opening between 40 and 80 mm and evaluate management regulations for other fisheries.

    Project Name: ICAR Ad-hoc scheme on Elucidation of food safety issues related to fish-borne parasites of zoonotic potential in aquaculture produce

    • Several groups of helminth parasites viz; Monogeneans, Digeneans, Cestodes, Nematodes, Trematodes and Acanthocephalans were observed and among these, monogeneans and nematodes showed highest prevalence in Indian major carps.
    • Monogeneans: The occurrence of monogenean infections on gills was high during summer. Catla catla was highly susceptible to monogenean infection. Smaller size groups (10-15 cm) have showed more susceptibility compared to the larger ones.
    • Digeneans: The overall digenean infection was rare among the Indian major carps. Only a very few parasites were isolated from the gills region.
    • Cestodes: The prevalence of Cestodes was high in summer. The infection was more in larger size groups (i.e. 30-35 cm size group in case of Catla catla and Labeo rohita and 25-35 cm size groups for Cirrhinus mrigala).
    • Nematodes: Nematodes were abundant in the intestine during rainy season. Catla catla was highly susceptible followed by Labeo rohita and Cirrhinus mrigala. Nematode infection was more in smaller fishes (5-10 cm and 10-15 cm size groups).
    • Acanthocephala: Acanthocephalan infections were found to be highest during summer. The parasitic frequency index (PFI %) was more in 15-20 cm size groups (Catla catla) and 20-25 cm size groups (Labeo rohita).
    • Intermediate Host (Snail): Several cercarial and metacercarial stages of helminth parasites were observed in snails (Pila globosa) which are the intermediate hosts for these parasites. Biological method of control (introduction of ducks) was found to be most eco-friendly for fish ponds.
    • Zoonotic strains: Three zoonotic strains viz., Clonorchis sp., Capillaria sp. and Heterophyes heterophyes were isolated from Catla catla and Cirrhinus mrigala.
