Studies on the Mysidacea of the Indian coasts

The available literature on the mysidacea of the Indian waters centred mainly around the taxonomic and systematic aspects rather than or. the other facets of their biology or life history. A rich and varied m:jsid fauna exist in the littoral and shallow areas of the seas around India. Reports on the abundance of mysid population of the Indian seas reveal a greater concentration (74%) in the night-time collections indicating diel migrations, characteristic of the fauna. Thi? population density was high during the postmonsoon (October-January) in the shelf waters and during the premonsoon (February-May) in the oceanic region in the northwestern Arabian sea. In general, the oceanic area off Veraval, Cape Coniorin and the northern neritic area off Cochin are delineated as densely populated zones. Higher numbers (150-450/lOOm^) are reported to occur in the inshore waters of Cochin during the south west monsoon. In the Bay of Bengal the population of mysids occurred throughout the year ever, in the deeper layers beyond 200m. The predominance was prominent (63%) during the premonsoon and to lesser extent (23%) \n the northeast monsoon seasons in the neritic area. In the northwestern Bay of Bengal and the Andaman-Nicobar islands ecosystem the mysidacea were present in larger numbers in the depth zone of 50-100m and 100 - 200m in the southwesten region

Priced fish catches discarded at Kalamukku fish landing centre

The success of marine fishing industry depends on the efficiency and performance of a plethora of departments like vessel manufacturers, net makers, ice plants, cold storages, exporters and retail outlets. If any of the departments fail wholly or partially, it cripples the industry and the people most affected are ultimately the fishermen who toil hard in the sea to earn a livelihood

Efficient Unsteady Model Estimation Using Computational and Experimental Data

Improving aircraft simulations for pilot training in loss-of-control and stalled conditions is one goal of NASA research in the System Wide Safety Program. One part of this effort is to develop appropriate generic aerodynamic models that provide representative responses in simulation for a given class of aircraft. In this part of the flight envelope nonlinear unsteady responses are often present and may require an extended aerodynamic model compared to that used in the conventional flight envelope. In this preliminary study, two objectives are addressed. First, to obtain a representative model for a NASA generic aircraft at an unsteady condition in the flight envelope and second, to evaluate the techniques involved. To meet these objectives, two different generic aircraft configurations are modeled using both experimental and analytical data. With these results, an initial assessment of the efficiency and quality of the tools and test techniques are evaluated to develop guidance for analytical and experimental approaches to unsteady modeling
