Some aspects of productivity in relation to fisheries of Indian neritic waters

It is generally accepted that tropical seas are less productive than the temperate waters to the north and south of the Equator. Large concentrations of nutrients are characteristic of Polar waters and areas influenced by these waters are rich in anima~ and plant life. In rem• perate waters ule nutrients accumulated during the \",inter months support the burst of phytoplanktonic growth which reaches its peak with increasing sunligh

Fishermen's share in consumer's one Rupee – A case study

To study the price spread of some of the commercially important fishes, Sakthikulangara (r.ear Quilon in Kerala), the biggest landing centre in our country was selected as primary market and Kottarakkara, Punalur, Kozhencherry and Chengannoor (all ia Southern Kerala) as consumer markets. Data on fish prices at the landing centre and at the consumu markets and expenditure on transportation, handling and other marketing aspects have been collected during July to September 1981. Details of classification of purchasers, pecentage distribution of the quantity lifted by them and the marketing channels have been studied

Share of fishermen and middlemen in consumer price : A study at Madras region

An attempt has been made in this paper to discus the marketing margins, and producer's and middlemen's share in consumer's rupee for commercially important varieties of marine fish in Madras region of Tamil Nadu. Pudumanikuppam which is a major mechanised landing centre as primary market, Chintatripet as wholesale market and Pattalam, Chinuatripet, Saidapet and Vadapalani (all in Madras City) as consumer markets were selected for the study. Data on landing, wholesale and prices of selected varieties of fish were collected 15 to 20 days in each quarter during April 1984 to March 1985 by following the marketing channel

Costs and earnings of trawlers operating at Tuticorin Fisheries Harbour (Tamil Nadu)

The article provides the economic statistics of the fishing trawlers operating in the Tuticorin fishing harbour. The trawlers operating at Tuticorin Fisheries Harbour were mostly purchased during the period from 1973 to 1985. Trawlers of 9.5 to 10 m were introduced at Tuticorin Fisheries Harbour. Most of the sample units in this category were purchased in 1984 and afterwards. Based on the economics of operations of different sizes of trawlers it seems that investment on bigger size boats of 9.5-10 m in the Tamil Nadu coast is advisable and introduction of bigger boats with longer operational range will further help to avoid the conflict between the mechanised and traditional fishermen

Study on Marketing Structure and Price Behavior of Marine Fish in Tamilnadu

Marine fishermen in India are said. to be suffered by way of not getting the due price for their produce. The difference between. the price of fish paid by the consumer end received by the fishermen is considered to be large. The pricing efficiency is concerned with improving the operation; buying, selling and other connected aspects or marketing process so that it will remain responsive to consumer direction

Fry of the milk-fish Chanos chanos (Forskal)

It is well known that the fry of the milkfish Chanos chanos; (Forskal), appear in large numbers In the tidal flats of the Pamban area, especially near the Chinnapalam creek. Observations of Delsman (1929), in the indonesian waters have shown that the fish larvae appeal first in the summer months of April and May, and later in the months of September, October and November

Some aspects of adaptation in Chanos chanos (Forskal)

The possibilities of culturing marine species of fishes in coastal belts containing salt or fresh-water have received much attention in recent years, following the lead given by Far Eastern countries in the culture of Chanos. In India, Chanos as well as species of mullets could be cultured on a large scale and a beginning in this direction has already been made in certain South Indian • centres. A study of the mechanism of adaptation in these species is an essential prerequisite to any rational system of culture, since it will help in determining the optimal values of salinity and temperature of the environment for the various species

Traditional fishermen in low income trap — A case study in Thanjavur coast of Tamil Nadu

The technological changes and consequent improvement in fishing methods like the introduction of synthetic nets and motorisation of country crafts have considerably paved the way to reduce the stress and strain of traditional marine fishing and to a certain extent improved the living conditions of fishermen. The present investigation was carried out at Keechankuppam and Mallipattinan villages in Thanjavur coast of Tamil Nadu to study the socio-demographic status of fishermen pertaining to housing, literacy, family size and occupational pattern, to assess the ownership and level of investment of fishing equipments, to analyse the income and expenditure pattern of fishermen families and extent of indebtedness along with credit facilities available in the village and to find out the major constraints confronted by the fishermen inhibiting their socio-economic development and to suggest necessary remedial measure

Costs and earnings op trawl operations along Nagapattinam coast of Tamil Nadu

The lucrative external market for shrimp and constant rise in the mechanised trawl fishing fleets not only enhanced the marine fish production of our country but also showed the way for the growth of an organised sea food export industry and increase in employment opportunities in the subsidiary sector. In this context, a study was undertaken at nagapattinam centre of Tamil Nadu coast where the operation of ordinary trawlers and pair trawlers is common. The study indicates that pomfrets contributed to more than 50 per cent of the revenue of pair trawlers and prawns about 50 percent of the revenue of trawlers. The pair trawling further provided a new technique to fishermen of this region to harvest the hitherto underexploited valuable resources like pomfrets, rays, croakers, clupeids, carangids and perches in substantial quantity. The introduction of single and two boats high opening trawl nets not only served as diversification of the existing bottom trawling but also directed to redeploy many units to catch commercially important finfishes depending upon the seasonal abundance. The trawl catch forms more than 90 per cent of the mechanised landings and 50% of the total landings of the state. The study indicates that both types of fishing are economically efficient
