Length-Based Spawning Potential Ratio (LB-SPR) model was applied to describe the status of Javelin grunter, Pomadasys kaakan in the Persian Gulf and Oman Sea. From April 2002 to March 2019. 45,489 specimens were collected from fish landing sites monthly, and their length (FL) and weight were measured. The results of the present study showed that different gears captured most of the P. kaakan be...

The banded coral shrimp, Stenopus hispidus (Crustacea: Decapoda: Stenopodidea) is a popular marine ornamental species with a circumtropical distribution. The planktonic larval stage lasts ∼120-253 days, indicating considerable dispersal potential, but few studies have investigated genetic connectivity on a global scale in marine invertebrates. To resolve patterns of divergence and phylogeograph...

This study examines the ability of a temperate marine fish, Hexagrammos decagrammus, to modulate its prey capture behavior in response to differences in prey type. This species has an extremely broad diet, feeding on prey which demonstrate very different anti-capture behaviors. Video-taped attacks on three shrimp species, one crab and pieces of shrimp were analyzed to determine the relative con...

The tropical shrimp genus Synalpheus includes the only eusocial marine animals. In much of the Caribbean, eusocial species have dominated the diverse fauna of sponge-dwelling shrimp in coral rubble for at least the past two decades. Here we document a recent, dramatic decline and apparent local extinction of eusocial shrimp species on the Belize Barrier Reef. Our collections from shallow reefs ...

Tropomyosin has been reported to be responsible for the cross-reactivity between shrimp and dust mites and the measurement of tropomyosin specific IgE was found superior to shrimp extract for the predicting of shrimp allergic reaction. A total of 55 dust mite allergic patients were recruited to analyse the cross-reactivity between shrimp and mites . Tropomyosin specific IgE for shrimps (rPen a1...

in temperate forests canopy gaps play an important role in driving stand dynamics. the purpose of this research was to compare soil characteristics in forest gaps with several size and its relation to beech regeneration density in lalis forest, chalous. in order to investigate factors, three gap sizes as small gap (200 m2), medium gap (400 m2), and large gap (600 m2) with three replicate were s...

At the present study, the distribution of Cd, Hg and Pb in water and their accumulation in fish species (silver carp, rainbow trout and shrimp) in three different farms. Totally 63 samples of three species and the water of their ponds were obtained during summer 2008 from Gilan, Mazandaran and ChabaharIran. The concentrations of three heavy metals in fish and shrimp flesh were measured by flame...

Marine biological invasions have been regarded as one of the major causes of native biodiversity loss, with shipping and aquaculture being the leading contributors for the introductions of alien species in aquatic ecosystems. In the present study, five aquatic alien species (one mollusk, three crustaceans and one fish species) were detected during dives, shore searches and from the fisheries on...
