Abstract
Compared to 2018, marine fish landings during 2019 increased by 2.1% from 3.49 million tonnes to 3.56 million tonnes. In terms of total marine fish landings, Tamil Nadu overtook Gujarat after several years. Emergence of the Red toothed trigger fish (Odonus niger) a major resource was unusual with simultaneous reduction in landings of Indian oil sardine and mackerel. Six cyclonic storms in a year along the Indian coast was also an unprecedented climatic phenomenon. In 2019, marine fish landings was valued at Rs.60,881 crores at landing Centre and Rs.92356 crores at retail Centre. CMFRI prepared and published minimum legal size proposals for resources of Tamil Nadu (113 species) and Maharashtra (58 species). Management plan for marine fisheries of Gujarat, non-detriment findings on silky and thresher sharks of Indian Ocean, policy advisory and guidance for good mussel farming practices, advisories and precautions for jelly fish fishers are some noteworthy outputs. A National Mariculture Policy 2019 (NMP 2019) was submitted to the Department of Fisheries (DoF) and National Fisheries Development Board (NFDB). A Working Group 3 Report [Fisheries, Aquaculture and Fish Processing] for developing a road map to Blue Economy of India was submitted to the Economic Advisory Council to the Prime Minister (EAC-PM). Otolith and statolith research in fisheries was used for environmental impact assessment, as well as taxonomic ambiguity resolution. Otoliths were also used to make jewelry. In the area of marine environment management research, Blue carbon stock of sea grass meadows of Palk Bay was quantified, 3D profile of the blue carbon stock of sediments of the mangroves from Vembanad Lake was analysed, changes in the breeding patterns of three pelagic bird species viz., Sooty tern, Brown Noddy, Great Crusted Tern were recorded at Pitti in Lakshadweep. In the area of mariculture, CMFRI installed 2608 cages all over the country. First spawning and hatching of Siganus vermiculatus was achieved. Micronursery hatchery system (down welling and upwelling system) developed at Vizhinjam has yielded 0.2 million seed of green mussel seeds which were supplied to the State Fisheries department for farming. Seed/yolk sac larval production of fishes viz., Indian pompano (3.4 lakhs), orange spotted grouper (100,000), Lethrinus lentjan (100 lakhs), Penaeus semisulcatus (PL15–500 lakhs) and Sepioteuthis lessoniana (1950) were produced and distributed to selected beneficiaries and private entrepreneurs for marine cage and coastal pond farming/sea ranching. CMFRI closed the life cycle of one food fish Siganus vermiculatus (Rabbit fish) two more marine ornamentals– Pseudanthias squamipinnis (Sea goldie or lyretail coralfish) and Dascyllus melanurus (Four stripe damselfish). CMFRI also produced designer clowns– Platinum, Snow flake, Picasso, Tear drop; alongwith year round production of other clown fishes such as, Percula clown, Tomato clown, Skunk clown and Maroon clown. A marine ornamental shrimp Lismata amboinensis was also bred in captivity. Natural spawning of F1 generation of Indian pompano was achieved in RAS system. For the food fish basket, CMFRI successfully achieved the broodstock development in captivity of marine finfish species viz, Pomadasys furcatus, Acanthopagrus berda, A. latus and Lutjanus johnii.
