  Fisheries and Aquaculture are playing an important role in addressing nutritional and livelihood security, especially of the rural poor in developing countries. Fish are rich sources of protein, essential fatty acids, vitamins and minerals. The fats and fatty acids in fish, particularly Omega 3 fatty acids, are highly beneficial and difficult to obtain from other food sources. The growing gap between supply and demand globally will impact on the health and nutrition of low income families, unless efforts are made to increase the production to meet the growing demand. Aquaculture is the culture of Aquatic organisms under controlled conditions. Present concept of aquaculture incorporate culture of all aquatic organisms by following certain management techniques which includes water quality,choice food etc. and to protect them from unwanted predators, diseases, pollutants or any other things which are harmful to them. The aquatic organisms which are normally used for aquaculture for food purpose include fishes, prawns, shrimps, crabs, mussels and some live food organisms like algae and zooplankton.

  Climate change and livestock rearing are interrelated processes, both of which take place on a global scale. Livestock play an important role in economy of the developing countries like India. FAO estimates that per capita livestock production and productivity have been stagnant over the last two decades. This has been attributed to a number of production and productivity constraints including global climatic change. Climate affects livestock both directly and indirectly. Direct effects from air temperature, humidity, wind speed and other climate factors influence animal performance: growth, milk production, wool production and reproduction.Indirect effects include climatic influences on the quantity and quality of feedstuffs such as pasture, forage, grain and the severity and distribution of livestock diseases and parasites. Understanding the impact of climate change on livestock productivity is crucial to mitigate theadverse impact on the gains from other efforts.

  Sea buckthorn commonly known as “Cold Desert Gold” due to its high potential as a bio-resource for land reclamation, reducing soil erosion, medicinal and nutritional properties in the leaves & fruits. In India, it’s fruit is also known as Leh berries or miracle fruits. In ancient Greece, the leaves of Sea buckthorn when added to horse fodder were found to result in weight gain and shiny hair, thus the Latin name ‘Hippo’ means Horse and ‘Phaos’ means Gloss or flare i.e. ‘Hippophae’ meaning shining horse is an ancient plant with modern virtues, due to its nutritional and medicinal value. All parts of Sea buckthorn e.g. berries, leaves, and seed or pulp oils contain many bioactive compounds. They are a rich source of natural antioxidants such as ascorbic acid, tocopherols, carotenoids, fla-vonoids, while they contain proteins, vitamins (especially vitamin C), minerals, lipids (mainly unsaturated fatty acids), sugars, organic acids and phytosterols. livestock and human studies suggest that sea buckthorn may have various beneficial effects: cardioprotective, antiatherogenic, antioxidant, anti-cancer, immunomodulatory, anti-bacterial, antiviral, wound healing and anti- nflammatory. Several studies showed that the leaves & fruit residues of SBT could be used to feed poultry and livestock without accumulation of toxins and the feed also had a stimulating effect on growth and performance of poultry birds & livestock. Therefore, it would be worthwhile to perform more scientific research on this medicinal plant and to promote its largescale utilization for livestock and poultry health, production & welfare.

  The giant freshwater prawn, Macrobrachium rosenbergii is the largest prawn known in the world. It is also known as Scampi. Its farming is gaining popularity all over the world. It is the most preferred species for culture because it has fast growth rate, better meat quality, resistance to disease, omnivorous feeding habit, compatibility for polyculture with Indian and Chinese carps, adaptation to varying environmental conditions, easy breeding and good demand in domestic and international markets (Gupta 2006; New 1995, 2005).

 An investigation was undertaken to determine the extent of genetic diversity present among 52 proso millet genotypes using D2 statistic. Cluster analysis grouped 52 germplasm into six clusters based on the degree of divergence between the genotypes. Maximum number of 27 and 17 genotypes were grouped under cluster I and IV, respectively, while clusters III had three genotypes and clusters II and V consisting of 3 genotypes each and cluster VI had single genotype. Maximum inter cluster was observed between cluster V and VI (30.96) followed by cluster II and VI (28.47). The greater the distance between the two clusters indicates wider the genetic diversity between genotypes. Hence, the genotypes in cluster V viz., CO 5, 23/1 had wider diversity with PCGP 49 in cluster VI and these lines may be utilized in further breeding programme for the exploitation of hybrid vigour. The intra cluster distance was maximum in cluster V (13.77) followed by cluster I (11.40) indicates hybridization involving genotypes within the same clusters may result in good cross combinations. Among the six traits studied, maximum contribution was made by single plant grain yield (49.55%) followed by days to 50 per cent flowering (26.62%) and number of productive tillers (17.04%). Hence, grain yield, days to 50% flowering and number of productive tillers together contribute 93.21% towards total divergence. Therefore, these characters may be given importance during hybridization programme.
