Draft Genome Sequence of the Luminescent Strain Vibrio campbellii LB102, Isolated from a Black Tiger Shrimp (Penaeus monodon) Broodstock Rearing System.

Abstract: We report here the genome sequence of Vibrio campbellii LB102, isolated from the broodstock rearing system of a shrimp hatchery in India Sequence analysis revealed the presence of effector toxins of the type III (YopT, sharing 39% identity with Yersinia pestis) and type VI (VgrG-3 and hemolysin coregulated protein of V cholerae) secretion systems

The complete mitochondrial genome of the Anabas testudineus (Perciformes, Anabantidae) and its comparison with other related fish species

Abstract: In the present study, the complete mitochondrial genome sequence of Anabas testudineusis reported using PGM sequencer (Ion Torrent, Life Technologies, La Jolla, CA). The complete mitogenome of climbing perch, A. testudineusis obtained by the de novo sequences assembly of genomic reads using the Torrent Mapping Alignment Program (TMAP), which is 16 603 bp in length. The mitogenome of A. testudineus composed of 13 protein- coding genes, two rRNA, and 22 tRNAs. Here, 20 tRNAs genes showed typical clover leaf model, and D-Loop as the control region along with gene order and organization, being closely similar to Osphronemidae and most of other Perciformes fish mitogenomes of NCBI databases. The mitogenome in the present study has 99% similarity to the complete mitogenome sequence of earlier reported A. testudineus. The phylogenetic analysis of Anabantidae depicted that their mitogenomes are closely related to each other. The complete mitogenome sequence of A. testudineus would be helpful in understanding the population genetics, phylogenetics, and evolution of Anabantidae.

Scale Construction to Measure the Attitude of Farmers towards IARI-Post Office Linkage Extension Model

Abstract: Addressing a lot of marginal and small farmers in developing country like India, ICAR-Indian Agricultural Research Institute introduced an alternate approach to public extension as IARI-Post office Linkage Extension Model in 2009 to reach out the grass root farmers with improved frontline technologies in remote villages through Branch post masters. In the initial expansion phase, there is a need to analyze the impact and future perspective of the model in relation to farmers' behaviours. Interpreting farmers' orientation towards the model could be measured through Original Research Article Sahoo et al.; AJAEES, 37(4): 1-13, 2019; Article no.AJAEES.53794 2 attitude scale construction with the new concept. Likert-type scale was considered with statements preparation and validation through juries' method and relevancy score method. The scale was pretested in a non-sample area. Item analysis of thirty-six (36) filtered statements could reduce to eighteen (18) reliable attitude statements in the final scale with accepted \"t\" values. The reliability test showed the scale was quite reliable through Cronbach alpha value as 0.75 and split half reliability full test value as 0.72 after Spearman-Brown correction. The scale was found to be valid through content validity and known group method test. The scale was administered to the sample farmers with five point continuum response in the Likert scale would categorize farmers into five classes like least favourable, less favourable, favourable, highly favourable, very highly favourable attitudes. Measuring attitude through a standardized scale of stakeholders facilitates future strategy and decision making by policy makers. It can be further validated in meeting several future innovative extension methods.

E-optimal block designs under heteroscedastic model

Abstract: This paper mainly studies the E-optimality of block designs under a general heteroscedastic setting The C-matrix of a block design under a heteroscedastic setting is obtained by using generalized least squares Some bounds for the smallest positive eigenvalue of C-matrix are obtained in some general classes of connected designs Use of these bounds is then made to obtain certain E-optimal block designs in various classes of connected block designs

Cautionary note about non-linear models in fisheries

Abstract: A large number of research^ papers in journals dealing with non-linear models in fisheries, if nothing else, is a testimony to the fact that such models play a very important role in this area. For example, studies on length-weight relationship (Ai^anasastry 1989, Dcvadoss 1989. Jayasankar 1989, Premalatha 1989). estimation of fecundi^ (Piska and Waghniy 1989, Hoda and Qureshi 1989) and synthetic models (Kurian 1989), all involve models in which the parameters appear in a non-linear manner.
