पिंजऱ्यातील मत्स्यशोति विषयक व्यापार आणि आर्थिक सुसाध्यता/शक्यता

India is one of the largest fish producers in the world and contributes 5.43% to global fish production. India ranks second in fish production from aquaculture sector following China at top. Total fish production of India during 2010-11 was 8.42 million metric tones. Inland sector contributes about 5.2 million metric tones, whereas marine sector contributes 3.22 million metric tones. India has a long coastline of about 8,129 km and continental shelf area of 0.5 million km2. Declining catch rates in marine capture fisheries consequently created serious unemployment issues in rural coastal areas. Issues faced by marine fisheries sector in India have focused the attention of policy makers and rural fishers towards development of mariculture and coastal aquaculture activities as alternative livelihood option

Report on morphological abnormality in Scylla serrata

Morphological abnormalities most commonly reported in crabs are alterations in carapace (mainly number and shape of antero-lateral teeth), chelipeds, walking legs and shape of the abdomen. Uran, a fishing village in Raigad district of Maharashtra, supports a good fishery of Scylla serrata commonly known as giant mud crab, found in the coastal estuarine and mangrove areas

Turtle conservation activities in Tambaldeg village, Sindhudurg district, Maharashtra

Tambaldeg village in Devgad taluka is a famous tourist place in the Sindhudurg district. During a field visit to Tambaldeg beach on 24th April 2017, six carcasses of adult olive ridley turtle Lepidochelys olivacea and one of green turtle Chelonia mydas were observed in decomposed state. This beach is a turtle nesting site and the Forest department of Maharashtra with the support of local fishers is undertaking awareness programs for turtle conservation including hoardings displayed on conservation of turtles along the beach. Protection of nesting turtles and eggs is also undertaken by the local communities

Heavy landings of snappers at Mumbai with notes on the biology of Lutjanus argentimaculatus (Forsskal, 1975) and Lutjanus johnii (Bloch,1792)

Snappers are considered valuable seafood delicacy and enjoy great demand in international market. Snapper landings in Maharashtra have increased over a period of time. The major species of snappers landed in Maharashtra is Lutjanus johnii which is accompanied by occasional landings of Lutjanus argentimaculatus

आरोग्याची देखरेख आणि रोगांचे व्यवस्थापन

The culture of marine finfish in cages was successfully initiated in Japan in 1950s and in South East Asia during 1970s. In the initial years of cage culture, fish seed for culture was collected from the wild. Recent developments in hatchery technology and seed production of commercially important marine finfish and shellfish have ensured the continuous supply of seed for mariculture practices. The disease control and health management are important issues for sustainable aquaculture. The disease occurrence causes major economic loss to aquaculture farmers. Production costs often increase due to disease outbreaks and treatment procedures followed to overcome death of fishes during culture. In natural aquatic environments, disease problems are unnoticed as diseased/weak/stressed fishes are easily removed by predators and very few occurrences of disease outbreaks are reported. Moreover in natural environment fish are not crowded as in captive culture conditions, which ultimately causes stress in fishes frequently

Observations on the fecundity of Rhynchobatus djiddensis (Forskal, 1775)

The resource is not targeted but is landed as a by-catch. However, when compared to 1960s and 1970s the landing of R. rijiddensis are very less indicating overfishing. As it is included as a Vulnerable (VU) one in the mCN Red list the fishes should be tlu'own back in to the sea, if alive, as a conservation measure. There is also a need to emphasise the need to conduct the detailed maturity and reproduction studies for better conservation practices. The observations in respect of the fecundity of this species in this contribution can be used as a baseline data for further studies on the reproductive biology of the fish which would help in formulating a conservation policy towards sustaining and conserving this specie

भारतातील आणि महाराष्ट्रातील पिंजऱ्यातील मत्स्यपैदास : सद्य आणि भविष्यातील प्रगतीच्या संधी

Sea farming is a popular area of aquaculture practice throughout the world. In Asian countries, it is rapidly growing to meet the increasing demand of high value marine fishes. Although India has a tradition of aquaculture, sea farming ventures on commercial scale were lacking. In this context, Central Marine Fisheries Research Institute started open sea floating cage culture activities in 2006-07 with Department of Animal Husbandry, Dairying and Fisheries (DAHD&F), Government of India assistance. Indigenous cage of 15 m diameter was fabricated following Norwegian open sea floating cage design and launched at Visakhapatnam. There was a technical setback with the design of cage, and consultation with Indian Institute of Technology, West Bengal helped to overcome technical issues with the cage structure. Open sea floating cage diameter was reduced to 6 m and 14 new open sea floating cages were launched at Sutrapada (Gujarat), Vasai (Maharashtra), Mangalore (Karnataka), Cochin (Kerala), Pulicat (Tamil Nadu), Nellore, Kakinada, Baruva (Andhra Pradesh) and Balasore (Odisha) in participation with National Fisheries Development Board (NFDB)

Heavy landings of threadfin breams at Sassoon Docks, Mumbai

At Sassoon Docks (new jetty), which is a major fish landing centre in Mumbai, heavy landings of threadfin breams were observed on 19th July 2011. The catch was dominated by Nemipterus japonicus and Nemipterus mesoprion
