Preliminary study on the rearing of Chilka prawn ('Kantala') Penaeus indicus H. Milne-Edwards in the brackish water ponds at Keshpur (Orissa)

Results of experimental rearing of Penaeus indicus without supplemental feeding in unfertilized brackish water ponds in fore-shore of Chilka lake are presented in this paper. Higher rate of survival was recorded where advanced juveniles were stocked and lower rate of survival was recorded where early juveniles were stocked. The average growth rate recorded from the rearing experiments was higher than the average growth rate of Penaeus indicus recorded from the adjoining Chilka Lake which indicates the promising future of prawn farming in and around the lake. Analysis of gut contents revealed that Penaeus indicus could efficiently utilise algal and higher plant matter present in the ponds. No noticeable differences in daily growth rates were noticed between early and advanced juveniles in rearing experiments

Preliminary observations of the use of under-water light in fish catch

Experiments with drift gill net with under-water lights were carried out in the sea and estuarine region along with a control net of the same specifications without any light in the same fishing ground for comparison. The experimental net caught more fish in number and weight than the control. Fishes like pomfrets (Pampus chinensis, Parastromafeus niger), seer (Scomberomorus spp), hilsa (Ilisha spp) etc showed positive phototaxis and were gilled encircling the point of illumination. Young skates (Mobula spp) and Polynemus tetradactylus were antiphototactic. The number of fishes caught increased with increase in period of illumination. The catch of larger fishes was maximum at 60 mts of illumination and the total catch increased with increase in intensity of light. Additional cost of operation with under-water light was Rs 1-25 per hr but the catch was 4 to 5 times greater than that of the control net

A Survey of Automated Process Planning Approaches in Machining

Global industrial trend is shifting towards next industrial revolution Industry 4.0. It is becoming increasingly important for modern manufacturing industries to develop a Computer Integrated Manufacturing (CIM) system by integrating the various operational and information processing functions in design and manufacturing. In spite of being active in research for almost four decades, it is clear that new functionalities are needed to integrate and realize a completely optimal process planning which can be fully compliant towards Smart Factory. In order to develop a CIM system, Computer Aided Process Planning (CAPP) plays a key role and therefore it has been the focus of many researchers. In order to gain insight into the current state-of-the-art of CAPP methodologies, 96 research papers have been reviewed. Subsequent sections discuss the different CAPP approaches adopted by researchers to automate different process planning tasks. This paper aims at addressing the key approaches involved and future directions towards Smart Manufacturing

Range extension of a mantis Shrimp <em>Harpiosquilla harpax</em> (Family: Squillidae) in the Chilika Lagoon

18-24The present study describes the first live occurrence of a species of mantis shrimp i.e. Harpiosquilla harpax from the Chilika lagoon. It was a new record to Chilika after the opening of natural inlet due to super cyclone Phailin during October 2013 and range extension from Visakhapatnam coast.  However, concrete information regarding its population and spatio-temporal distribution is certainly not known. since it was caught as by catch. Food and feeding behaviour and morphological structure of the compound eye and ommatidia was also studied

Empowering married young women and improving their sexual and reproductive health: Effects of the First-time Parents Project

The Population Council, in partnership with Child In Need Institute in Kolkata, Deepak Charitable Trust in Vadodara, and International Institute for Population Sciences, Mumbai, initiated the First-time Parents Project in India to develop and test an integrated package of health and social interventions to improve married young women’s reproductive and sexual health knowledge and practices, enhance their ability to act in their own interest, and expand their social support networks. The project was formulated on the hypothesis that the periods immediately following marriage and surrounding the first pregnancy and birth offer a unique and powerful entry point for improving the situation of married young women. Findings indicate that the intervention had a significant, positive net effect on most indicators reflecting married young women’s autonomy, social support networks, partner communication, and knowledge of sexual and reproductive health. However, the net effect of exposure to the intervention was mixed with regard to indicators related to gender role attitudes and attitudes toward domestic violence, as well as reproductive health practices. The experience of the intervention demonstrates that it is feasible to improve married young women’s reproductive health knowledge and practices, expand their sources of social support, and involve them in activities with peers in safe spaces outside the home, and through the process empower them in their marital and familial relationships. The report suggests that this model could also be integrated into existing NGO or government services, and could be tested for implementation on a larger scale
