Domestication and broodstock development of the Indian tiger shrimp Penaeus monodon

The Indian tiger shrimp P. monodon is the most suitable species for culture along the Indian coast because of its fast growth, hardiness and high price demand. With the establishment of a number of hatcheries all along the Indian coast and consequent large-scale production of seed, culture practice has been extended to vast area on extensive and semi-intensive scale

Diversity and exploitation status of Crustacean Fishery Resources in India

India is blessed with long coastline of about 8118 km along the West Bengal, Odisha, Andhra Pradesh, Tamil Nadu and Pondicherry along the east coast; along Gujarat, Maharashtra, Goa, Karnataka, Kerala along the west coast. India has 2.02 million sq.km exclusive economic zone area and 0.53 million sq.km continental shelf area, a potential source for marine fisheries.The rich continental shelf area, a good habitat for demmersal fishes as well as crustaceans such has penaeid prawns , non-penaeid prawns, crabs, lobsters and stomatopods. Mechanised trawler is the main gear operated in the continental area targeting crustacean resources, Though trawl net is operated for penaeid prawn, non penaeid prawns, crabs and stomatopods will be formed as by catch because all these resources habituate in the same fishing ground

Shrimp culture during 1998 - 2000 at marine fish farm, Regional centre of CMFRI, Mandapam Camp

With the introduction of trawlers in the Palk Bay and Gulf of Mannar during 1960s under lndo- Norwegian Project exploitation of shrimp began and it has reached commercial scale during 1970s as many private entrepreneurs initiated trawl fishin

Heavy landing of juveniles of lizardfish Saurida undosquamis (Richardson) at Visakhapatnam

Andhra Pradesh has a coastline of 974 km and continental shelf area of 33,227 km. The annual marine fish landings of the state ranged from 2,08,305 to 2, 33,900 t during 2006 to 2009 with an annual average landing of 2, 22,928 t. Highest catch of 2,33,900 t was observed in 2009 and lowest of 2,08,305 t in the year 2007. Among the demersal resources, lizardfish is one of the dominant group. Lizardfish is sold and consumed in both fresh and dried condition at Visakhapatnam and is preferred by poor people as a protein supplement and also used in value added products. Lizardfish is locally called ‘Badematta’ and it supports a regular fishery

Green Tiger Prawn Penaeus semisulcatus (De Haan, 1844)

Green tiger prawn is a commercially important penaeid shrimp species, dominant in the coastal waters of Tamil Nadu. Grows to 230 mm and 270 mm in TL in case of males and females, respectively

Tuna fish waste as an aquafeed substitute at Visakhapatnam

Tuna is an important group of large pelagics in the waters along the Visakhapatnam coast and constitute a major component of the exploited marine fishery resources. The annual average landings of tunas in Andhra Pradesh during 2006 -2010 was 29,360 t, which accounts for 26.4% of the national tuna catch. The highest catch of 32,369 t was recorded in 2009 and the lowest catch of 27,046 t was recorded in 2006. Visakhapatnam alone contributes to half the total tuna catch for the state. The tuna fishery at Visakhapatnam is contributed mainly by Euthynnus affinis and Thunnus albacares with small amounts of Katsuwonus pelamis and Auxis thazard. They are mainly exploited by hooks and line and by gillnets. They are locally called ‘suralu’ and support a regular fishery. Visakhapatnam is the major fishing harbour where tuna fish is brought from different landing centres and transported for export

Studies on Biochemical Composition of Haemolymph and muscle of Penaeid Prawns, Metapenaeus monoceros(Fabricius), Penaeus monodon Fabricius; and P. indicus H. Milne Edwards

The thesis deals with the biochemical composition of the most important tissues, haemolymph and muscle, of M. monoceros, P . monodon and P . indicus in the wild state and under cultured conditions in the brackishwater ponds. Observations on the sex-wise, length-weight relationships in these prawns are integrated to provide a meaningful interpretation. Similar studies were made on variation in the biochemical composition of haemolymph and muscle in relation to sex, size, weight and condition factor. The intra and inter - relationships between the different factors operating at the different phases of growth and maturation of gonads are investigated to bring out the significant factors. There were no earlier studies on these lines in literature

Study on Mangrove Ecology and Impact in Kakinada Bay

The southern fringes of the Kakinada Bay are predominantly mud-flats interrupted by creeks/rivers which traverse, at the hayw ard end , through dense forests of mangrove as mentioned by Ramasarma and Ganapathi (1968) in their study on the Bay hydrography. The larger trees are located at a height of 03 m in relation to creek river low water level but in high tide and spring tides major parts are innundated. A part of the system forms a fringe along the eroding creek/river banks with roots in the water but on the bay-ward side the trees are succeeded by vascular plants, the shrubs and grasses on the mudflats due, probably, to show encroachment and reclamation for human habitation and paddyfields. especially in Matlapalem creek (Rajyalakshmi. 1975). However, the creeks are highly saline in non-monsoonal seasons, deep with a directional flow towards the Bay

Evidence of the existence of resistance/tolerance to WSSV in Penaeus monodon

year. As foreign exchange winner, shrimp played a significant role by contributing 49 to 76% (Rs.3645 crores) to total export during 1978-2003. During 1977-88, the shrimp export was just 51,000-55,736 tones, however, from 1988- 89 to 2002-2003 a spectacular growth could be recorded culminating at 1, 34,815 tones. This growth was mainly due to the contributions from aquaculture sector, which in 2002—2003 alone amounted to 1, 15,320 tones. The shrimp production from wild has been gradually declining from 50,000 tones during the eighties to 19,495 tons in 2002-2003 due to over exploitation of commercial species. The Indian tiger shrimp Penaeus monodon is the principal species which contributes to the cultured shrimp production in the country
