The Otolithes ruber is considered a valuable fish in the Indo-West Pacific. Estimates of the Q/B ratio and parameters of equations to ‘predict’ Q/B values for O. ruber in northwestern part of the Persian Gulf and the effects of different age-groups (age 1 to 6 year) on prey are presented. The age and food item of O. ruber were recorded on data collected from monthly samplings by bottom tra...

Crustacean hyperglycemic hormone (CHH) has many functions to regulate carbohydrate metabolism, ecdysis and reproduction including ion transport in crustaceans. The cDNA encoding CHH peptides containing 369 bp open reading frame encoding 122 amino acids was cloned from eyestalk of white shrimp (Litopenaeus vannamei) and was produced by a bacterial expression system. The biological activity of re...

Pacific white shrimp Penaeus vannamei that were pre-exposed to Taura syndrome virus (TSV) and then challenged with yellow head virus (YHV) acquired partial protection from yellow head disease (YHD). Experimental infections were carried out using specific-pathogen-free (SPF) shrimp which were first exposed per os to TSV; at 27, 37 and 47 d post infection they were then challenged by injection wi...

A 90-day feeding trial was conducted to evaluate the effects of formic acid (FA) and astaxanthin (AX) on growth, survival, immune parameters, and tolerance to Vibrio infection in Pacific white shrimp. The study was divided into two experiments. In experiment 1, postlarvae-12 were randomly distributed into six groups and then fed four times daily with six experimental diets contained 0.3 % FA, 0...

A new species of commensal shrimp of the genus Typton from holothurians is described and illustrated. The specimens were collected from a single specimen of Holothuria (Halodeima) inornata Semper, 1868 at a depth of 7 m. This is the first record of an association between a shrimp of the genus Typton and echinoderms. With this record, five species of Typton are now known from the eastern Pacific...

White spot syndrome virus (WSSV), the causative virus of disease, is found in most shrimp farming areas in Iran, and it cause large economic losses to the shrimp farming industry. Shrimp aquaculture is an important industry in Iran and plays an important role in aquaculture production. The shrimp production in 2012 was more than 12000 metric tonnes and it is estimated it will reach 20000 tonnes...

The Integrated Tropical Coastal Zone Management at AIT is an area of specialization under the Schools of Environment, Resources and Development and Civil Engineering. This interdisciplinary field aims to develop human resources for coastal zone management in the Asia and the Pacific regions where the coastal areas encompass a diverse array of resources and ecosystems with intense human activiti...

BACKGROUND The Deepwater Horizon oil spill of 2010 prompted concern about health risks among seafood consumers exposed to polycyclic aromatic hydrocarbons (PAHs) via consumption of contaminated seafood. OBJECTIVE The objective of this study was to conduct population-specific probabilistic health risk assessments based on consumption of locally harvested white shrimp (Litopenaeus setiferus) am...

This study evaluated the effects of lipid sources on replacement fishmeal with Clostridium autoethanogenum protein (CAP) in diet Pacific white shrimp ( Litopenaeus vannamei ). By using CAP to replace 40% basal (contains 25% fishmeal), four diets (PC as control diet, LSO low soybean oil level, MSO middle and HSO high level) were formulated by adding different proportions fish oil. Each was assig...
