this study was conducted to estimating the amount of non-standard sizes (with lengths less than lm50) fishes of shrimp trawls in the hormozgan province coastal water during shrimp fishing season. sampling was carried out using the tabas otriger commercial trawler during 55 hauls. eight commercially valuable species including pampus argenteus, parastromateus niger, plicofollis dussumieri, saurid...
Investigating the relations and mechanisms of coexistence among sympatric species is essential to comprehend their ecological roles in the food webs. In the present study, the diet and trophic interactions of 5 abundant teleost species coexisting in the northern Oman Sea were examined using stomach contents analyses. The cumulative prey curves showed that the sample size of each studied species...
Scanty information exists pertaining to the length-weight relationship (LWR) and length-length relationship (LLR) parameters of longsnouted catfish, Plicofollis argyropleuron in lotic systems throughout the northern part of Peninsular Malaysia. It is vital to reveal these biological properties of P. argyropleuron in Kuala Muda and Merbok estuary for future management and to increase knowledge a...
in this paper age determination and morphological characteristics of blacktip catfish, plicofollis dussumieri, from oman sea were evaluated. a total of 132 fish specimens were collected from fishing trawlers or landings from march 2011 to july 2012, with minimum and maximum of 245 mm, 195 g; and 767 mm, 5801 g, respectively. maximum life span was 12 years for the length range of 245 – 767 mm fl...

سه گونه ماهی گل خورک periophthalmus waltoni، boleophthalmus dussumieri و scartelaos tenuis متعلق به خانواده گاوماهیان می باشند که در سواحل گلی جزر و مدی زندگی می کنند. با توجه به اینکه مطالعات کمی در خصوص زیست شناسی گونه های مذکور در ایران صورت نگرفته، بنابراین اهداف اصلی این پژوهش بررسی زیست شناسی تولیدمثل، رژیم و عادات غذایی و پویایی شناسی جمعیت این سه گونه ماهی می باشد. بدین منظور نمونه برد...
Study of fish food habits is effective to determine artificial feeding and design theories of food relations. For this purpose, food habits of catfish, Plicofollis dussumieri that lives in Tiab beaches, located in Minab between summer 1395 to spring 1396 was performed. Thirty specimens were caught in each season so a total of one hundred and twenty specimens were taken and morebiometric of spec...

The usage of invasive tagging methods to assess lizard populations has often been criticised, due to the potential negative effects of marking, which possibly cause increased mortality or altered behaviour. The development of safe, less invasive techniques is essential for improved ecological study and conservation of lizard populations. In this study, we describe a photographic capture-recaptu...
