Socio - economic implications of purse seine operations in Karnataka
The total marine fish production in India rose from about 0.9 million tonnes in 1969 to about 1.4
million tonnes in 1978. One of the major reasons for the increase in production is the mechanisation of
fishing operations. The present account deals with the findings of an investigation to study the socioeconomic consequence on Rampani fishennen due to commercial purse seine operations in the Kamataka waters. The article incorporates some of the results of an earlier study (Dharmaraja and Jacob, MS) and the information obtained from a special survey in the Kamataka coastal villages recently conducted by a team of scientists of C.M,F.R.I. A perusal of the gearwise estimates of marine
fish landings in the Kamataka coast shows that the landings from purseseines have been steadily increasing during the years 1977to 1979 (1st half)
Rationality of the use of factors of production by small trawlers along Calicut coast
The purpose of the present study is to evaluate the economic rationale of input use by small
trawlers in Kerala Coast. In order to estimate the production elasticities of different inputs, a Cobb-
Douglas type of production function was fitted to the pooled data on coast and earnings of 50 trawlers
for a period of 10 years from 1971-72 to 1980-81, obtained from Kozhikode Regional Fish Marketing
Co-operative Society. For functional analysis, vessel-wise gross returns (in rupees) was taken as
dependent variable and number of days fished, fuel expenditure (in rupees) and repairing and maintenance
charges (in rupees) as independent variables. Marginality analysis was also done to evaluate
the eflSciency of input use.
The production function as well as the marginality analysis indicated that the increase in the
number of days fished would lead to higher gross income. So also increase in oil expenditure from
mean level would yield a more than proportionate increase in gross income. However, repairing
and maintenance cost had a negative impact on fishing income which indicated that the vessel owner in
his own interest should be cautious in the operation to avoid frequent repairs and to reduce the delay
in getting the vessels repaired
Seizing opportunities to diversify conservation
Conservation Letters published by Wiley Periodicals, Inc. This article identifies, and offers several ways to address, a serious, persistent issue in conservation: low levels of diversity in thought and action. We first describe the lack of diversity and highlight the continued separation of the environmental conservation and environmental justice movements. We then offerтАФbased on previous research and our collective experienceтАФtwo suggestions for how to increase inclusivity (a step farther than increasing diversity) in holistic ways. We suggest that embracing narrative, including historical narrative that can be profound and painful, may be essential to addressing this deeply rooted issue. We also suggest the need to redefine тАЬenvironmentтАЭ to more closely align with the diversity of perspectives that different people and disciplines bring to the topic. We support our suggestions with selected data from empirical research and provide examples of initiatives that embody them
Evaluation of sampling gear for demersal resource surveys
The three demersal trawls evaluated were 38 m HSDT-II, indigenously developed
by CIFT for deep sea fishing in Indian EEZ; and two imported designs, viz.,
45.6 m Expo model demersal trawl and 50 m fish trawl operated from vessels of FSI
and IFP, respectively. Vertical opening at trawl mouth was heighest for 50 m fish
trawl (3.2 m), followed by Expo model demersal trawl (2.5 m) and 38 m HSDT-II
(2.2 m), due to differences in overall dimensions and design features. Estimate of
horizontal opening between otter boards was highest for 38 m HSDT-II probably due
to low drag of the gear, followed by 45.6 m and 50 m trawls. Lowest catch per unit
effort obtained by 38 m HSDT-II is presumably due to smaller dimensions of the gear,
larger codend mesh size and difference in ground rig, in addition to chance factors.
However, 38 m HSDT-II scores on several features desirable in demersal sampling
gear such as simplicity in design and construction, ease of operation; lower twine
surface area and drag; and ground rig suitable for wider range of bottom conditions.
Modifications to make it more effective while sampling for crustaceans and small sized
finfish components are described
A bibliography of parasites and diseases of marine and freshwater fishes of India
With the increasing demand for fish as human food, aquaculture both in freshwater
and salt water is rapidly developing over the world. In the developing countries,
fishes are being raised as food. In many countries fish farming is a very important
economic activity. The most recent branch, mariculture, has shown advances in
raising fishes in brackish, estuarine and bay waters, in which marine, anadromous and
catadromous fishes have successfully been grown and maintained
