An overview of the marine fish landings in Andhra Pradesh during 2014

The estimated marine fish landings in Andhra Pradesh during the year 2014 was 3.41 lakh tonnes (t) as compared to 2.66 lakh t in 2013 showing an increase of 28%. The state’s contribution to the all India landings during 2014 was 9.5 %. Resources such as Indian mackerel and lesser sardines constituted the maximum, being 16.3% and 12.2% of the landings respectively. Tunnies and penaeid prawns landings contributed 8% each while the other important species/ groups were ribbon fishes 5.9%, carangids 5.5%, perches 4.2%, croakers 3.8%, oil sardine 3.5%, goatfishes 2.3%, seer fishes 2.3%, Stolephorus spp. 2%, crabs 2%, Silverbellies 1.9% and elasmobranchs 1.6%. Landings of crabs, Indian mackerel, oil sardine, lesser sardines, seer fishes and tunnies had increased by 0.4, 0.65, 1.04, 2.32, 0.56, 1.07 times respectively when compared to 2013 landing trends. Other clupeids and silverbellies had decreased when compared to the previous year landings

Marine fish landings in Andhra Pradesh during 2015-an overview

Andhra Pradesh with a coastline of 974 km and spread over nine districts supports a rich marine fishery constituted by several groups of fishes, crustaceans and molluscs. About 1.5 lakh fishermen are directly or indirectly involved in the marine fisheries sector

Indian marine fishery resources: optimistic present, challenging future

Marine fish production from capture fisheries in India has increased by about six fold during the past six decades. Export earnings from the marine sector crossed 12,000 crores in 2010-11 and gross revenue through marine fish landings at the point of first sales was about 20,000 crores. Marine products are now exported from India to nearly 100 countries. Monitoring the harvest of different marine fishery resources is very much essential for planning and implementing policies for sustained production from the sea. The dynamic changes in the landings of marine fishery resources over the last six decades were examined after classifying them into 26 different resource groups. Decadal averages of landings of different resource groups were compared using Student’s t test and coefficient of variation was worked out for each decade. Present status of each resource group was examined separately based on a simple criterion. Out of the 26 groups examined, 18 were found to be under the ‘abundant class, 5 under ‘less abundant’ class and one each under ‘declining’, ‘depleted’ and ‘collapsed’ classes. Elasmobranchs, threadfins, ribbonfishes, mullets and flatfishes are the five resource groups falling under ‘less abundant’ class. White fish falls under ‘declining’ class, flying fishes under ‘depleted’ class and unicorn cod under ‘collapsed’ class. All the other groups fall under the ‘abundant’ class indicating that most of the resources (73%) are in healthy condition. The ‘depleted’ and ‘collapsed’ classes require management interventions for the recovery of the resources and the group falling under ‘declining’ class needs caution and care to prevent further reduction in the stock

Overview of the marine fish landings in Andhra Pradesh during 2012

Andhra Pradesh, with 974 km of coastline and continental shelf area forming 31,000 sq. km, is rich with many species of prawns, carangids, Perches, croakers and elasmobranchs. During 2012, the estimated marine fish landing of Andhra Pradesh was 3.04 lakh t

Marine fisheries of the south-east coast of India during 2008

The south-east coast of India comprising the states of Andhra Pradesh, Tamil Nadu and Pondicherry have a total coastline of 2050 km which is 34% of the total coastline of the country. This region is more diverse with respect to the number of species that are landed. In 2007, it was observed that 499 species were landed in Tamil Nadu, 294 in Andhra Pradesh and 115 in Pondicherry

SS Cancri: the shortest modulation-period Blazhko RR Lyrae

In order to study the Blazhko effect, we characterise the modulation of the RR Lyrae star SS Cancri, which has been reported to have the shortest modulation Blazhko period. B, V and R band data have been acquired. The pulsation period is 0.36731 +- 0.00004 d. No significant change in the period over the last 80 years is observed. We measure a periodic variation in the light curve maxima, which has a period of 5.313 +- 0.018 d and an amplitude of 0.016 +- 0.003 mag. The best model that describes the Blazhko effect is the resonance coupling between a low and a high order radial mode

Multi-lepton signals from the top-prime quark at the LHC

We analyze the collider signatures of models with a vector-like top-prime quark and a massive color-octet boson. The top-prime quark mixes with the top quark in the Standard Model, leading to richer final states than ones that are investigated by experimental collaborations. We discuss the multi-lepton final states, and show that they can provide increased sensitivity to models with a top-prime quark and gluon-prime. Searches for new physics in high multiplicity events are an important component of the LHC program and complementary to analyses that have been performed.Comment: 7 pages, 4 figures, 2 table

Demographic and socio-economic changes in the coastal fishing community of India

The spatial and temporal changes in the demographic and socio-economic indicators of coastal fishing community of India were studied using data collected during the national level census on marine fishermen population in 2005 and 2010, covering 11 maritime states and union territories of the country. Information on population growth, sex ratio, literacy level and educational status, poverty level, sectoral dependency and occupational categories of the coastal fisherfolk were analysed and compared with analogous figures of national averages on these socio-economic indicators. The marine fishermen of India, who depend on fisheries for their subsistence, were significantly below the national averages in many of key demographic indicators. The results of correspondence analysis carried out for visual description of the association of economic status with the key indicators showed that, the below poverty class among fishermen were more associated with low family size compared to large sized families, which implicates to labour supply in a labour demanding socio-economy of marine fisheries. Different dependency ratios were computed as a simple summary measure for comparison of age structure of fisherfolks

Marine fisheries of the south-east coast of India during 2009 - 2010

The south-east region consisting of Andhra Pradesh, Tamil Nadu and Puducherry is spread over a coastal length of 2,050 km and as per the Marine Fisheries Census 2010, this region has 785 landing centres, 1,168 marine fishing villages, 3.7 lakh fishermen families and 14.63 lakh fisher folk. The estimate of total marine fish landings in 2009 for the south-east region was 8,05,295 t accounting for 25.1% of the total marine fish landings in the country
