Draft Genome Sequence of Vibrio parahaemolyticus Strain VP14, Isolated from a Penaeus vannamei Culture Farm.

Abstract: Here, we report the draft genome sequence of an isolate of Vibrio parahaemolyticus, VP14, recovered from the gut of Penaeus vannamei shrimp farmed in southern India. The genome of VP14 comprised 5,224,046 bp with a GC content of 45.3% and contained 5,326 genes, including 4,972 coding sequences.

Harvest Losses at Various Resources of Inland Fisheries

Abstract: To properly plan loss reduction strategies, information on the magnitude of losses is important. The up-to-date data on harvest and post harvest losses in inland fisheries from different sources are not available in Indian context. The need of such estimates has become all the more important. Hence, a pilot study was undertaken with the objective of assessing the harvest losses at various inland fishery resources in East Godavari, West Godavari and Khammam districts in Andhra Pradesh, and Hirakud reservoir in Orissa. The extent of losses were found to be 2.40% in freshwater aquaculture, 1.86% in brackishwater aquaculture, 6.52 to 8.89% in reservoir fisheries, 3.69 to 4.48% at landing centres of lake, 8.56 to 13.94% in riverine fisheries and 6.32% in estuarine fisheries. An effort has also been made to identify the causes for these losses, which have been discussed in detail in this paper.

A note on variance estimation of ratio estimator in two phase sampling

Abstract: An alternative estimator of the variance of the ratio estimator under the two phase sampling scheme has been proposed. The proposed variance estimator is approximately unbiased and more efficient than the existing classical estimator due to Cochran (2) and Rao-Sitter (6) under a linear superpoulation model with intercept.

Two-dimensional balanced sampling plans excluding adjacent units under sharing a border and island adjacency schemes

Abstract: In Balanced Sampling Plans Excluding Adjacent Units (BSA plans) first order inclusion probabilities are equal and second order inclusion probabilities are zero for pairs of units at a distance less than or equal to m and are constant for pairs of units which are at a distance greater than m. These plans are useful when the adjacent units in the population provide similar information. In this paper, an algorithm based on linear programming approach has been developed for construction of two-dimensional BSA plans under sharing a border and island adjacency schemes for m ≤ 2. Some results on existence of such BSA plans have also been obtained for each adjacency scheme separately.
