Significant Achievements in the last 5 years
- Database on catch, effort and species composition of elasmobranchs, threadfinbreams, flatfishes, lizardfishes and sciaenids exploited by different gears in the Malabar region were prepared.
- Prepared database on age, growth, mortality parameters, size at recruitment, length at first capture, probability of capture, spawning stock biomass, recruitment size, fecundity, mean length, length at first maturity and other parameters on C. limbatus, N. mesoprion, N. japonicus, C. macrostomus, J. sina and O. ruber to assess the impact of fishing on these resources and as an input for developing ecosystem based fisheries management models.
- Data base on trophodynamics of N. mesoprion, N. japonicus, C. macrostomus, J. sina and O. ruber exploited in Malabar region was prepared.
- Low-value bycatch (2007-2009) and discards (2008-2011) from trawl were studied.
- Rearing of Malabar red snapper in the beach farm at Calicut has shown that this species is suitable for culture along this coast.
- The broodstock of Malabar Red Snapper (Lutjanus argentimaculatus) were developed in silpoulin lined pond at Beach Farm of CMFRI, Calicut.
- Low-cost rectangular cages of size 2.5x1x1 m were designed and fabricated using PVC pipes. Cost of the cage including the maturing and labour charges is approximately. Rs 3000/.
- Culture of pearl spot (Etroplus suratensis) was successfully demonstrated using low-cost cages to the farmers of Thiruvangoor, Calicut district.
- Carrying capacity in the mussel farming areas of Padanna Estuary was studied, which indicated positive impact on the physical and ecological carrying capacity of this estuary.
- Proposed a new conceptual value chain on rock oysters KONKAN MINI OYSTERS considering the rock oyster populations in Maharashtra and the high local demand for oysters both in Maharashtra and Goa.
- Training on bivalve farming being regualry conducted
- Pathological manifestations of the acanthocephalan, Tenuiproboscis sp. in the mangrove red snapper, Lutjanus argentimaculatus was traced.
- Studies the infection of Perkinsus spp. in bivalves from Versova (Perna viridis), New Ferry Wharf (Meretrix meretrix), Sasoon Dock (Crassostrea madrasensis), Miyani, Navibandar and Porbandar (Crassostrea madrasensis).
- Studies indicated that Beypore beach is prone to more anthropogenic activities than other beaches in Calicut. The plastics and other non-biodegradable wastes showed 80% higher quantity in Beypore than other beaches in Calicut.
- Stranding of dolphins, whales and porpoises were recorded in the Malabar area and a database of marine mammals was prepared.
