  Citation × Citation Citation Abstract Copy Title: Small-Scale Fisheries Transition to Sustainable and Responsible Fishing In India - A Micro Level Study Author: Kanthiah, Pazhani Small-scale fisheries play an important role in generating employment, income and livelihood to the fisherfolk. It constitutes 81 per cent of the total fisheries sector in India. But, this sector remains neglected and the fisherfolk are socially and economically backward. Even after six decades of planned development nearly 62 per cent of the fisherfolk families do not possess crafts. Resource constraints coupled with absence of fishing and other related infrastructures in most of the fishing villages compel fishermen households to migrate to earn their livelihood. Migrant fishermen formed a new village and follow simple method of fishing, which are eco-friendly, economical in the use of fuel and gears. Their responsible fishing is useful for fishing without any by-catches and wastage of marine resources. With this theoretical background, this paper is framed in such a way to analyze the factors that contribute to the transition of small-scale fisheries to sustainable and responsible fishing in Tamil Nadu, India. Factors which hamper small-scale fisheries development have been discussed. The main focus of the study is on the impact of fishermen migration on the socio-economic status of migrants and also the sustainability of fishing operations without class conflict. Policy implications emerging in the light of the findings of the study are also given briefly.

  Citation × Citation Citation Abstract Copy Title: Applying Parallel Genetic Algorithms to Economic Problems: The Case of Agricultural Land Markets Author: Balmann, Alfons, Happe, Kathrin Year: 2001 This paper elaborates the use of distributed Genetic Algorithms (DGA) to study an artificial land rental market. The study is based on a spatial comparative-static model in which a number of spatially ordered agents (farms) compete in an auction for renting land. Each agent’s behavior is determined by a genetic algorithm that is applied to an agent specific population of genomes representing particular bidding strategies. Agents interact directly through a migration mechanism that allows to spread renting strategies across the population of agents as well as indirectly over the rental market. Two market constellations are considered and different simulations with a variety of parameter constellations (migration rate, placement of farms, etc.) are run: First, a situation of limited market access is defined. A series of simulation experiments shows that for this scenario the DGA generates results that fit comparative static equilibrium conditions like allocative efficiency and zero-profits. Second, in a limited market access scenario, only under very special conditions the DGA generates results that comply with oligopolistic behavior. The results of the two scenarios are analyzed and discussed as to the influence of the DGA procedure itself and a possible economic and game theoretic interpretation.

  Citation × Citation Citation Abstract Copy Title: Marine Reserves: a Closer Look at What They Can Accomplish Author: Anderson, Lee G. Year: 2001 The presents a theoretical analysis of the operation of a commercial fishery in the presence of marine reserves. The sustainable yield and revenue curves for reserves are derived and compared to the analogous curves with no reserves. It is shown that reserves will always reduce the sustainable harvest for any total stock size but in certain, but not all cases, they can provide a positive minimum possible stock size. The effects of different reserve sizes and speeds at which migration takes place on economic and boilogical variables are discussed. It is shown that marine reserves and TACs can both achieve a specific equilibrium biomass level, but they will have different biological and economic effects.
