Institutional Analysis of Marine Fisheries Management Practices in Kerala, India

The study is important for the fact that it places the management dynamics of marine fisheries sector in the context of growing unrest of local communities over the emerging resource conflicts and degradation Economic crisis in small scale marine fisheries due to high operating cost continue to hinder the efforts towards conservation in many ways The migration of mechanized fleet as a response to profit maximization strategy of enterprises continues to be a threat to resource management Therefore this study explores how to revamp the small scale mechanized sector effectively and profitably to ensure rational allocation of resources The thesis attempts to examine how livelihood vulnerabilities of artisanal fish workers influence the crafting of management institutions Finally by combining insights of an institutional framework the study establishes the need for recognising the role of both formal and informal institutions in the management of marine fisheries in Kerala

Integrated Management for Sustainable Development of Coastal Zones – A Gis Based Study on the Central Kerala Coast

The present study focuses on the stability of the coast, exploitation of the coastal resources, human activities within the study are that extends from Fort Cochin at north to Thottappally at south, central Kerala State and hinterlands, socio-economic problems of the coastal community and the environmental issues arising in the recent past due to human activities. The objective of the study is critically analyse the coastal zone region and prevailing situation and to propose a comprehensive management plan for the sustainable development of the region under study. The thesis covers varied aspects of coastal uses like fisheries, tourism, land use, water resources etc. To critically examine the above scenarios, the ILWIS (Integrated Land and Water Information Systems) – GIS software has been used. A satellite image of the area has been used for the coastline change detection and land use patterns. The outcome of the present study will be beneficial to the various stakeholders within the coastal region and its hinterlands. To further add, this study should find better applications to similar or near-similar situations of Southeast Asia where identical scenarios are noticeable.

Marine Actinomycetes as Source of Antiviral Agents and as Probionts for Penaeus monodon Culture Systems

The present study revealed the importance of marine actinomycetes as a potent source of bio active secondary metabolites. The selected isolates were capable of protecting Peaneus monodon against WSSV infection. They also proved to be inhibitory to vibrios and is a rich pool of hydrolytic enzymes. Their capacity to proliferate in saline environments and their property of non-pathogenicity to prawns makes them good candidates to be applied as probionts in penaeid shrimp aquaculture. They also enhanced the immune status of shrimps challenged with WSSV and act as a good source of antioxidants. Exploitation of the potential for the prophylactic and therapeutic measures in aquatic animal health management would be highly rewarding. This work is a preliminary study targeting marine actinomycetes as a source of antiviral compounds and as probionts in Penaeus monodon culture systems. More work is needed to understand the nature and mode of action of the bioactive compound, the various aspects of immune and antioxidant responses under challenge and when exposed to pro active treatments, and the dose and frequency of application of such compounds under rearing conditions.

Studies on certain exploted marine finfish resource of India

This thesis Entitled Studies on certain exploited marine Finfish Resources of india.Marine fish catch forecasting is short term or long term basis for purposes of explation and management. Among the short term forecasts, two approaches need serious consideration in India: 1. to improve the methods of understanding the influence of environmental characteristics on the abundance or availability of fish in different areas in different periods and to make the forecasts of the same, 2. to make analysis of time series catch data (ARIMA models) to make forecasts of catch in the next year or in a particular period during next year. There is some evidence of suitability of these approaches to Indian marine fisheries but attempts aiming at comprehensive studies should be made. In the area of long term forecasts, considerable work is done in India on single species assessments but in the context of multi species, multigear nature of Indian marine fisheries, assessments of all species together in a mixed fishery are urgently required for effective managements of fisheries.

The Impact of Integrated Marine Fisheries ‘Development Project Among the Artisanal Fishermen in Kerala

Despite various intervensions, artisanal fishermen remain one of the weaker sections in Kerala's society. Host of the welfare and developmental programmes introduced for them had produced very little impact on their living conditions. Further, they are unable to compete with mechanised sector for fishing. Host of the technological development which had taken place after Indo-Norvegean Project favoured the growth of mechanised sector. As a consequence of this, fishing become unviable for artisanal fishermen who propagate the idea of ” sustainable development” in the fishing industry. It is commonly believed that an integrated approach may help them to improve their living conditions substantially. In the light of the above background the scholar has made an attempt to study the impact of Integrated Marine Fisheries Development Project among artisanal fishermen in Kerala It is realised from the findings of the study that the most important needs of artisanal fishermen arecredit facilities and marketing support. Without marketing linkages effective credit management is not possible. Marketing activities and credit management are interdependent

Role of Commission Agents in the Development of Traditional Marine Fisheries of Kerala with Special Reference to Financing

The study clearly brings out the role of commission agents in the traditional marine fisheries sector and thereby goes to set at rest the controversy regarding their role. The findings of the study has important implications for formulation of policies and development strategies related to the traditional marine fisheries sector. The study points out the need for a thorough review and reformulation of the policies and development strategies for efficiently achieving the development potential of the traditional marine fisheries sector and for improving the economic conditions of the fishermen. The study is based mostly on Alappuzha District of Kerala, covering all the 30 marine fishing villages, spread over the three coastal taluks, namely, Karthikappally, Ambalappuzha and Cherthala

Biostatistical evaluation and Management of sciaenid fishery with particular reference to Otolithes ruber (Schneider, 1801) andJohnieops sina (Cuvier, 1830) of Konkan coast

Fish, a natural resource, has received great attention from all over the world. since it provides a cheap protein, employment and income to the millions of people for centuries. So fishermen, industrialist and multinationals are trying to exploit the marine resources to their maximum benefit by using modern craft, advance fishing equipments and efficient gear. Fishery resources in the open system particularly in oceans, were considered to be unlimited. However, recent developments in the innovation of efficient craft and gear using well tested material fitted with modern equipments that have greatly enhanced the mobility of craft, agility of gear and the ability of equipments to locate fishery resources have proved otherwise. Hence as the exploitation increases with more effort entering the fishery, the catch per unit of fishing effort starts to decline due to the limitness of the resources. The heavy fishing pressure in the recent past led to commercial extinction of a number of stocks such as. the North Sea herring, California sardine, Japanese Sardine and Peruvian anchovy (FAO. 1968: Gulland, 1974). In India, seer fish from Palk-Bay declined due to uncontrolled fishing (Devaraj 1983).

Diversity and antimicrobial activity of Lactic Acid Bacteria from the gut of marine fish Rastrelliger kanagurta against fish, shrimp and human pathogens

Emergence of antibiotic resistance among aquaculture pathogens has made it necessary to look into environment friendly, effective and sustainable methods such as probiotic and immunostimulants among others.. In the present study, LAB were isolated from the gut of fish species namely Rastrelliger kanagurta and analyzed for their antibacterial activity against various fish, shrimp and human pathogens. Different LAB species such as Lactobacillus plantarum, L. bulgaricus, L. brevis and L. viridiscens were encountered in the gut of R. kanagurta. Several strains showed good activity against fish, shrimp and human pathogens. LAB from the gut of such marine species may be developed as possible probiont for environment friendly health management of fresh water, estuarine and marine species currently exploited in aquaculture
