The Persian Gulf is of great economical, environmental and political importance, and includes around 205 species of fishes that only some of them have been studied parasitologically. From the order Pleuronectiformes ( ray-finned fishes), Psettodes erumei (Psettodidae), Pseudorhombus elevatus (Bothidae) and Brachirus orientalis (Soleidae) were selected for the survey. One hundred and forty eig...
The study was conducted to obtain some information about temporal and spatial variations of multifilament drift gillnet catch communities in coastal waters of Hormozgan Province (Persian Gulf) from October to March 2014. Totally, seven families were identified including Scombridae, Carangidae, Carcharhinidae, Sphyranidae, Stromatidae, Belonidae, and Pesttodidae with total biomass of 73.03%, 12....
Based on light and scanning electron microscopical studies, the following five species of the Philometridae (Nematoda: Dracunculoidea) are described from female specimens collected from marine fishes off the southwestern coast of Java, Indonesia: Philometra lobotidis sp. n. from the abdominal cavity of the Atlantic tripletail Lobotes surinamensis (Bloch) (Lobotidae, Perciformes); Philometra jav...
Some major latitudinal trends in the physiology, population dynamics and ecology of flatfish are illustrated, and related to their ultimate cause: temperature-mediated difference of metabolic rate. The niche of tropical flatfish is then defined with some emphasis on Psettodes erumei in the Gulf of Thailand, and a hypothesis is derived to explain the generally low observed biomass-and hence recr...
رژیم غذایی ماهی کفشک تیزدندان psettodes erumei در آبهای ساحلی خلیج فارس از فروردین تا اسفند 1391 با نمونه برداری ماهانه 30 قطعه ماهی بررسی شد. میانگین طول کل و وزن نمونه های بررسی شده به ترتیب 39/9 ± 47/38 سانتیمتر و 79/756 ±92/986 گرم بود. بیشترین تعداد معده های پر و بیشترین مقدار شاخص گاستروسوماتیک در ماه های مرداد (04/2 ± 22/5) و شهریور (28/2 ± 84/5) و کمترین مقدار شاخص گاستروسوماتیک در فصل ...
In this research we assessed the concentration of total mercury in the muscle, liver and gill tissues of Indian spiny turbot, Psettodes erumei caught from Jask coastal waters in Hormozgan province. Fifteen fish specimen were caught using trawl in spring season 2008. After biometrical measurements and sex determination, muscle, liver and gill tissues were collected mercury was extracted from the...
The growth parameters, mortality rates and exploitation population dynamic parameters and exploitation rate of Psettodes erumei were assessed between July 2010 to June 2011 using length frequency analysis. The data were collected from landing sites of Jask, Bandar Abass, Kong and Qeshm Hormozgan province waters. Using total weight (W) and total length (TL) data, the length- weight relationship ...
