Mechanical properties of E-glass fibre reinforced nylon 6/6 resin composites

The tensile strength, tensile modulus, compressive strength, interlaminar shear strength and residual tensile strength of E-glass fibre reinforced nylon 6/6 resin composite with the variation of fibre volume fraction are characterized. The results are in line with the required limits of theoretical values

Possibility of using polythene lined ponds for Mariculture in sandy beaches

Vast stretches of sandy seashores are at present lying unutilised. These sandy areas are not suited for Agricultural operation. Neither are they considered suitable for aquaculture due to the porous nature of the Soil and resultant seepage of water. However, if this seepage of water could be prevented by some means these areas could be utilised for aquaculture purposes. Experiments have been conducted at the calicut Research centre of central marine fisheries research institute in this direction. These experiments have proved that the seepage of water through the soil could be prevented by suitably lining the ponds with black polythene film. Although the use of polythene film is quite prevalent in agriculture for various purposes, it has not so far been of much use in aquaculture. The conversion of these sandy shores into productive aquaculture ponds by providing polythene lining for them has shown bright possibilities of utilising extensive areas for aquaculture and a report on this method is presented here

Occurrence of mature Mugil cephalus along the Calicut coast

The mature Mugil cephalus has been reported from various parts of the country. This article reports on the observation of mature Mugil cephalus along the coast of Calicut for the first time. The observation on the mature Mugil cephalus from the Calicut coast is of interest especially in the context of renewed efforts to develop hatchery techniques for the species. It may be considered as one of the favourable conditions for development of hatchery at Calicut coast
