Genetic improvement of freshwater prawn, Macrobrachium rosenbergii (de Man) in India. Phase two: annual report for period January to December 2012

Macrobrachiurn rosenbergii is one of the widely cultured freshwater prawn species globally. India was the third largest producer of this species in 2007 and its aquaculture production rose to 43,000 metric tons (t) in 2005 froin less than 500 t in 1995. However, since then production has been declining and in 2008-09 it was 12,856 t, a reduction of more than 70% compared to 2005. There are several contributing factors to this decline, such as slow growth rate, poor survival, disease outbreaks, increase in cost of production, and availability of low risk alternative fish species. However, there is a consensus that poor seed quality leading to unsatisfactory growth and survival rates in ponds is one of the major reasons. Hence, the development of a systematic selective breeding program aimed at improving growth rate and ensuring high survival rate of this species was deemed a high priority. The Central Institute of Freshwater Aquaculture (CIFA), Bhubaneswar, India in collaboration with the WorldFish Center, Malaysia initiated a selective breeding program for this species in 2007.

National issues raised by IIMA study on development and management of freshwater aquaculture in India: a review

An examination is made of various issues regarding freshwater aquaculture development raised by the IIMA study on inland fish marketing in India. The following topics are discussed: 1)fish production and the resources; 2)desirability for refined methodology for assessment of fish production; 3)pond resource under fish culture; 4)conflicting data and 5)observation on research input for freshwater.

Prospects of fisheries development in India by 2000 AD

The fishery resources of India are extensive. The demand for fish for domestic consumption will be at least 10 million by 2000 AD. With proper planning and management, fish production from inland, brackishwater and marine sources can be increased to 5 million tonnes, 1 million tonne and 4 million tonnes respectively. But the increase in the last 37 years is approximately equals 2.1 million tonnes over the base level of 1950. If the present trend is continued, the expected fish production will be approximately equals 6 million tonnes by 2000 AD, and hence, only approximately equals 60% of the domestic demand can be met.

Sex ratios of Metapenaeus kutchensis George, George and Rao, 1963 and Parapenaeopsis sculptilis (Heller, 1862) in the Gulf of Kachchh, Western India

Sex ratio data of two species of penaeid prawns Metapenaues kutchensis George, George and Rao, 1963 and Parapenaeopsis sculptilis (Heller, 1862), occurring in the Gulf of Kachchh, were statistically analysed. A preponderance of females was observed in both the species and the ratio of male to female for both years combined for M. kutchensis and P. sculptilis was found to be 1:15 and 1:2.7, respectively. Chi-square analysis revealed significant difference in the sex ratio of the two species.

On the use of different natural baits for sea-fishing in India

Rod and line, hand-line, trolling line and fish-traps are the different types of fishing gears wherein suitable fish baits are employed with a view to luring the catch. The coastal fishermen of India mostly use different types of natural fish-baits to catch fishes like Perches, Carangids, Sciaenids, Scombroids and Elasmobranchs. The reactions of the fishes caught to the different baits used are quite varied. Successful line fishing operations very much depend on the fish-baits. A detailed record of the variety of fishes caught, types of fishing and different baits used by the coastal fishermen of India has been made.

A note on the production trend of marine shrimps in India

The paper reviews the production statistics of marine shrimps in the different maritime states of India from 1950 to 1962. It is pointed out that for a correct appraisal of the status of any fishery, it is necessary to have data on effort E and catch per unit effort in addition to the conventional data on catch C. A relationship between U and E has been developed and the status of the fishery of Metapenaeus dobsoni has been discussed in this connection with reference to the data on catch and effort obtained from trawler operations off Cochin.

The development of the freezing and export of prawns in India

The paper deals with an overview on the preservation of fish by freezing process. Until a few years ago the surplus catches of fish, prawns were being dried, salted or pickled. The Kerala coast had always yielded large catches of prawns and about 5000 tons of dried prawns were annually exported to Burma and other Eastern countries. The Government of India looking at the great potential of this industry, has now, with a view to encourage exports, provided a series of incentives towards this end.

Standardisation and mass production of shrimp trawlers and other fishing boats in India

This paper deals with the existing fishing crafts, new vessel types, boat building programmes, their standardisation and mass-production in India.

The future of shrimp processing industry in India

The future of the shrimp industry in India depends entirely on our export markets. Therefore the future of the industry must be related to the demand for shrimps in foreign markets. The most important market today for India is the United States. In the United States the domestic production of shrimps which was about 112 million pounds in 1950 has increased only slightly to 139.6 million pounds in 1965. However the consumption during the same period increased from 119.5 million pounds to 274.2 million pounds - the gap between home production and consumption is made up by imports.

Transportation of fish in India: problems and prospects

India has a long coast line of about 4,800 km along which fish landing centers are scattered. Fish catches are showing an upward trend consequent on rapid mechanization of fishing crafts. Economic utilization of the landed fish is an essential prerequisite for the proper development of Indian fishing and fish processing industries.

A participatory study of the traditional knowledge of fishing communities in the Gulf of Mannar, India

This is the first in a series of case studies undertaken by the International Collective in Support of Fishworkers (ICSF) to document the traditional knowledge of fishing communities dependent on marine and coastal resources in protected and conserved areas in different parts of the world. The study, done with the support of the Bay of Bengal Large Marine Ecosystem (BOBLME) project, documents the traditional knowledge of fishing communities in the Gulf of Mannar in the state of Tamil Nadu. It focuses on two fishing villages, Chinnapalam and Bharathi Nagar, whose communities have traditionally depended on Krusadai and Appa Islands for their livelihood. Traditional knowledge relating to oceanographic, meteorological, biological, ecological and navigational aspects of fisheries was documented. The study will be useful for researchers, students, scientists, policymakers, fishworker organizations, NGOs and anyone interested in the traditional knowledge of local fishing communities related to marine biodiversity and the customary use of fisheries resources and fishing practices.

Towards socially just and sustainable fisheries: ICSF workshop on implementing the FAO voluntary guidelines for securing sustainable small-scale fisheries in the context of food security and poverty eradication (SSF guidelines) report, 21 to 24 July 2014 , Puducherry, India

This publication is a report of the proceedings of the ICSF Pondy Workshop, which focused on the FAO’s Voluntary Guidelines for Securing Sustainable Small-scale Fisheries in the Context of Food Security and Poverty Eradication (SSF Guidelines). The workshop brought together 71 participants from 20 countries representing civil society organizations, governments, FAO, academia and fishworker organizations from both the marine and inland fisheries sectors. This report will be found useful for fishworker organizations, researchers, policymakers, members of civil society and anyone interested in small-scale fisheries, food security and poverty eradication.
