The objective of this survey was to provide a software ecological model to predict the incidence of WSSV in Litopenaeus vannamei ponds of Gwater area located in southeastern of Iran. The coding and grouping of effective factors, which were involved in the occurrence of White Spot Syndrome Virus (WSSV) including temperature, salinity, oxygen, pH, ammonia, silica, pond preparation and management ...

In Penaeus indicus neuroendocrine organs plays an important role in the growth and reproduction. In Penaeus indicus four different types of neurosecretory cells such as A cell, B cell, C cell, D cell were identified. The Eyestalk of Penaeus indicus shows many neurosecretory cells, but the Brain and Thoracic ganglion shows only few neurosecretory cells. After the unilateral Eyestalk ablation the...

This study was designed to evaluate the relationship between marbling score and breed-type (Bos taurus vs < or = 1/4 Bos indicus) on palatability of cooked beef. One thousand six hundred sixty-seven steers and heifers (1,337 Bos taurus and 330 Bos indicus x Bos taurus crosses) that had been managed and fed alike were used. Shear force and tenderness rating indicated that meat from Bos indicus c...

We sampled 119 Nelore cattle (Bos indicus), 69 harboring B. indicus mtDNA plus 50 carrying Bos taurus mtDNA, to estimate the frequencies of putative mtDNA single nucleotide polymorphisms (SNPs) and investigate their association with Nelore weight and scrotal circumference estimated breeding values (EBVs). The PCR restriction fragment length polymorphism (PCR-RFLP) method was used to detect poly...

Three experiments of 28 days duration were conducted in three size groups (

in this study brown algae, sargassum glaucescens and that found plenteously in persian gulf and bushehr coast, were collected and hot water extracts of them were lyophilized. f. indicus (11.32±1.20 g), after two weeks adaptation in shoghab research station dependent to iran shrimp research center, isrc, were immersed in seawater (39 ppt and 25±1 c○) containing hot-water extract of brown algae, ...

Some species of terrestrial lizards in wet-dry tropical climates reduce their body temperatures (T(b)'s) and activity and lower their metabolic rates during the dry season when food and water resources are scarce. However, semiaquatic lizards have access to water and presumably food throughout the year, so it is possible that they will not have the seasonal response seen in terrestrial species....
