An Assessment of Economic Losses due to Avian Flu in Manipur State

The impact of 2007 outbreak of avian flu in the state of Manipur has been reported. The loss due to the disease has been found to be 14 per cent of the total value of livestock outputs in the entire state. More than 3 lakh birds were culled and 24 tonnes of poultry feed was destroyed post-flu. It has been found that the more affected were the producers and the input industry than traders and retailers. In dealing with such eventualities, compensation should be adequate and timely so as to ensure better compliance for effective control and stamping out of the disease. The study has suggested that the compensation rates may be fixed as per the prevailing economic condition of less-developed states like in the North-Eastern region, taking into consideration flock size, family size of farmers, proportion of income from poultry to total family income, level of nutritional security achieved from family poultry and border status of the state.Livestock Production/Industries,

Spatial price integration and price transmission among major fish markets in India

The domestic fish marketing system in India deserves to be developed into a strong network of efficiently functioning markets, as more than three-fourths of the country’s total fish production is channellised domestically. With the unleashing of a new global economic order, the efficiency of markets needs to be dealt with utmost importance. The degree of spatial market integration and price transmission between the major coastal markets in India have been reported using monthly retail price data on important marine fish species. It has been observed that degree of integration and rate of price transmission differ according to species. The highest integration has been observed in mackerel, probably because of its affordability to all income classes, resulting in a wide consumer base. Among various markets, a near full transmission of prices has been observed between Kerala and Tamil Nadu markets, except in the case of shrimp. Even though a major landing centre, the price movement in Maharashtra market has been found independent of other markets. The spatial market integration between major shrimp markets in the country has appeared to be the least, possibly because of its greater market share outside the country. The study has suggested to devise strategies to bring about greater integration between these markets so that both fishermen and the fish-consuming community in the country are benefitted.Marketing,

Marketing System and Efficiency of Indian Major Carps in India

The Kolleru Lake area (KLA) in Andhra Pradesh being a predominant centre for carp culture is known as the ‘Carp Pocket of India’. This paper has described the highly efficient fish marketing system prevalent in the KLA and has compared it with the marketing of Indian Major Carps (IMC) in other major aquaculture states like West Bengal and Orissa and marine states like Maharashtra and Tamil Nadu. The marketing channels, market intermediaries, price spread and marketing efficiency have been presented. A comparison of the marketing channels at several fish markets has revealed that the price spread for IMC from Kolleru is highest at the Mumbai market and lowest at the Coimbatore market. Consequently, fishermen’s share in consumer price has been found highest for Coimbatore at 61.54 per cent and lowest for Mumbai at 47.06 per cent. Similarly, the marketing efficiency was the highest for Coimbatore at 2.60 and lowest for Mumbai at 1.89. Retail price for KLA carps has been found lower than locally cultured carps at various areas, reflecting the efficiency of the marketing channel in providing cheap fish transported over large distances and through a large number of intermediaries. The reasons for the efficient IMC marketing system at KLA have been discussed and the study has recommended the development of efficient fish marketing system in other parts of the country.Agricultural and Food Policy,

Effect of Aggregate Flakiness on the Compressive Strength of Concrete Cubes

In this paper effects of aggregate flakiness on the compressive strength of concrete cubes have been studied using experiments. Total 30 cubes have been cast using normal, 5% of 8 mm, 10 mm and 12 mm size of flaky aggregates and 10% of 12mm size of flaky aggregate. NDT of the cast cubes using rebound hammer and ultrasonic pulse velocity have been also carried out. Aall the cubes were tested for compressive strength. Based on these data, comparative studies have been carried out to quantify the effect of flakiness and salient conclusions are drawn.

Domestic fish marketing in India - changing structure, conduct, performance and policies

This study has been conducted in all the major coastal states and some selected inland states to understand the domestic marketing of fish in India. The total marketing costs of auctioneer, wholesaler, retailer, vendor, marine fishermen cooperative society and contractor/freshwater fishermen cooperative society have been found to be Re 0.98, Rs 8.89, Rs 6.61, Rs 4.50, Rs 6.00 and Rs 3.51, respectively. The marketing efficiencies for Indian major carps (IMC), sardine and seer fish have been found to vary from 34 per cent to 74 per cent, depending on the length of market channel. The marketing efficiency has been found more in the case of marine species than freshwater species, since the latter travel longer distances from the point of production to consumption centre, passing many intermediaries as compared to the former. The fisherman’s share in consumer’s rupee has shown variations across species, marketing channels and markets. The infrastructure facilities at most of the surveyed landing centres, fishing harbours and wholesale and retail markets have been found grossly inadequate and poorly maintained. The study has highlighted the need for formulating a uniform market policy for fishes for easy operation and regulation so that the country’s fish production is efficiently managed and delivered to the consuming population, ensuring at the same time remunerative prices to the fishers.Marketing,

Seed treatments for sustainable agriculture-A review

Seed treatment refers to the application of certain agents physical, chemical or biological to the seed prior to sowing in order to suppress, control or repel pathogens, insects and other pests that attack seeds, seedlings or plants and it ranges from a basic dressing to coating and pelleting. Introduction and ban of arsenic (used from 1740 until 1808) is the key milestones in the history of modern seed treatment till then a continuous research and advancement in this technology is going on. The technological advancement prepared a roadmap for refiningexisting seed treatment technologies and future work on technologies like fluid drilling as a way to sow germinated seeds where gel can also serve as a delivery system for other materials, seed priming advances the early phase of germination without redicle emergence. Another advanced technology, solid matrix priming (SMP) has been evaluated as a means to advances the germination of seeds and serve as a carrier for useful material too. Physical and biological seed treatments alone an alternative to chemicals or in combination with a chemical treatment are being used worldwide because of their environmental safety and socioeconomic aspects. Biological seed treatments are expected to be one of the fastest growing seed treatment sectors in the near future, in part because they are easier to register at Environment Protection Agency (EPA). Lack of awareness to seed treatments at farmer’s level is one of the limiting factors in disease management and hence, efforts should be made at farmer’s level to adopt the technology. Keeping the all above facts in mind, selected seed treatment technologies with their improvement and significance will be discussed in this review

First report of four deep-sea chondrichthyans (Elasmobranchii and Holocephali) from Andaman waters, India with an updated checklist from the region

This paper confirms the new distributional records of four rare deep-water chondrichthyans viz. sharpnose sevengill shark, Heptranchias perlo (Bonnaterre, 1788); bluntnose sixgill shark, Hexanchus griseus (Bonnaterre, 1788); bramble shark, Echinorhinus brucus (Bonnaterre, 1788); and sicklefin chimaera, Neoharriotta pinnata (Schnakenbeck, 1931) from the Andaman waters in the Indian EEZ. The above-mentioned four fish species have not been reported earlier from this region. More exploratory surveys in the region are essential to understand the diversity and distribution pattern which is essential for critical management actions. An updated checklist of chondrichthyans known from Andaman and Nicobar waters of India is also presented
