the lernaeopodidae is a cosmopolitan family of copepods parasitic on both elasmobranchs and teleosts in marine and freshwater habitats. trichiurus lepturus l. is a commercially valuable bentho-pelagic fish inhabiting continental shelves and slopes worldwide. in the present study 74 specimens of t. lepturus were caught in the persian gulf, 12 of which were infected with female brachiella trichiu...

This paper is a comprehensive study of the shrimp trawl by- catch from Bushehr coastal waters (N. Persian Gulf). Sampling operation was carried out in two shrimp fishing seasons using the (Saber and Jahanara) commercial trawlers Generally, 87.5% of the total catch was by-catch and 12.5% was target species (shrimp). The catch composition included: 114 species from 45 teleostei families, 13 speci...

A procedure is proposed by which recruit numbers and parental biomass of shrimps stocks can be derived, given a series of catch-per-effort data and estimates of a few ancillary variables. In the Gulf of Thailand, shrimp recruitment decreased with decreasing egg production, but increased with decreasing total (mainly fish) standing stock. The net result of these counteracting effects was an over...

In order to assess the dietary intake of polycyclic aromatic hydrocarbons (PAHs) by Kuwaiti population, concentrations of PAHs were determined in edible tissues of commercially important seafood (fish and shrimp) samples collected from fish markets in 2005. Naphthalene, phenanthrene, fluoranthrene, pyrene, benz[a]anthracene and chrysene were routinely detected in all samples analyzed. The conce...

severe discharge of sewage and industrial effluents into the persian gulf leads to the deposition of various types of heavy metals, especially lead and mercury, in the muscles of fish. total mercury and methylmercury contents were determined in the edible parts (muscle tissue, fillet) of two different most popular frozen fish species from the persian gulf to ascertain whether the concentrations...

non-commercial fish species of shrimp trawls were studied monthly from october 2005 to september 2006 in mahshahr creeks (darvish, doragh, bihad, ghazaleh, ghanam, zangi and patil). the trawl nets had a cod-end mesh size of 24mm. total catch was 6431 individuals weighing 55.5kg, and included 14 species of non-commercial fish species belonging to 14 families. the caught shrimp species were from ...

Background: Determination of digestive enzymes activity would provide critical information in the design of appropriate diet. Sobaity, Sparidentex hasta is found in the Persian Gulf and  cultured in countries adjacent to it. OBJECTIVES: This study investigated proteolytic, amylase and lipase activities in the intestine of Sparidentex hasta captured from the  Persian Gulf. METHODS: 60 immature S...

The manuscript reviews the available literature of 2015-2022 on microplastic content in commercially important fish species, molluscs and crustaceans Arabian/Persian Gulf. concentrations beaches, subtidal sediment, surface water different regions Gulf is evaluated, also. Overall, reported concentration marine organisms has been found to be less than for comparable waters such as Mediterranean S...
