Andhra Pradesh has a coastline of 974 km and continental shelf area of 33,227 km. The annual marine fish landings of the state ranged from 2,08,305 to 2, 33,900 t during 2006 to 2009 with an annual average landing of 2, 22,928 t. Highest catch of 2,33,900 t was observed in 2009 and lowest of 2,08,305 t in the year 2007. Among the demersal resources, lizardfish is one of the dominant group. Lizardfish is sold and consumed in both fresh and dried condition at Visakhapatnam and is preferred by poor people as a protein supplement and also used in value added products. Lizardfish is locally called ‘Badematta’ and it supports a regular fishery

Landing of Alopias pelagicus (Nakamura, 1936) at Visakhapatnam

Two specimens of the pelagic thresher shark Alopias pelagicus (Nakamura, 1936) were landed at Visakhapatnam Fishing Harbour on 28.06.2011. One specimen was male (Fig. 1) and the other was female. The male pelagic thresher shark measured 940 mm and weighed 900 g. The female measured 829 mm (caudal fin tip was absent) and weighed 750 g. The specimens were characterised by large eye size and very long upper lobe of caudal fin. According to Compagno (1984) and Fisher and Bianchi (1984), the pelagic thresher is ovoviviparous, with at least two young, born at a length greater than 96 cm

On Demand Feedback Analysis for Certification Process

Many companies provide certifications to other vendors to validate that the vendor’s product functions efficiently on their technology. But it so happens that the process of certification might take longer due to errors that pop up which the vendors will not be able to resolve. The vendors need to resolve the errors with the help of product owner’s engineers which is a lengthy and less efficient process. With this in regard, the solution of on-demand feedback analysis of the certification process proposed in this paper helps minimize the delay in the certification process

Lethrinus lentjan (Lacepéde, 1802)

Lethrinus lentjan has 10 spines and 9 soft rays in the dorsal fin, 3 spines and 8 soft rays in the anal fin. The base of pectoral fin has very few scales and sometimes may even be naked. This fish is distinguished by the reddish colour on posterior margin of the operculum, hence the name pink ear emperor fish. The base of the pectoral fin can also be red sometimes. Body is olive-greenish in colour, becoming lighter colour ventrally

ఆర్ధిక రంగములో బహిరంగ సముద్ర జలాల్లో తేలియాడే కేజులో చేపలసాగు (Economics of open sea floating cage culture of finfishes)

Considering the opportunities for increasing mariculture production in India, cage culture offers the farmers and entrepreneurs with the scope to lay the idle resources of Bay of Bengal and Arabian Sea for a productive use. However the adoption of any technology depends upon its economic performance. The rate of return per rupee invested is the economic indicator that guides the investor to invest in the particular activity

Economics and policies for open sea cage culture in Andhra Pradesh

The fisheries sector plays a significant role in providing employment, reducing poverty and promoting health. Fish is an extremely nutritious, a vital source of protein and essential nutrients. The sector provides employment opportunities to nearly 14.5 lakh people directly and indirectly in Andhra Pradesh. In recent years, sea farming is gaining popularity and a couple of finfish, shellfish species and some sea weeds are now being farmed. Ornamental fish farming also has a promising future and is likely to contribute to the overall growth of fisheries sector in the coming years. Good governance and good culture practices can enable fisheries to thrive sustainably. Therefore, the Government of Andhra Pradesh is unveiling the policy to create a suitable eco-system for the rapid growth of fisheries and aquaculture for the coming years

కేజు సాగుకు చేపజాతుల ఎంపిక (Species selection for cage culture)

Interest in cage culture has been revived as an alternative crop for farmers outside traditional fish farming areas and in areas with topography not conducive to construction of ponds. The selection of the appropriate species of fish is necessary for the success of cage culture system. Species selected for farming in floating net-cages should meet the necessary criteria for being a cultivable species

కేజు పర్యావేక్షణ (Cage Monitoring)

Monitoring is an integral part of any type of mariculture activity. A well conceived and designed monitoring programme is needed to promote good growth of fishes and to obtained optimal production in sustainable manner from cages. The major factors responsible for success are to be taken care during the cage culture monitoring

Dried tuna for export as a small scale industry in Andhra Pradesh

Yellowfin tuna (Thunnus albacares) formed an average 33.5% of the total tuna catch of Andhra Pradesh, during the past decade. Fishing grounds for yellowfin tuna off northern Andhra Pradesh at depths of 200 m and more are gainfully exploited by the local fishers since 2002 using motorized crafts (theppas) with hooks and lines and trolls. Since 2006 a few mechanized trawlers were also converted to long liners for catching tunas
