The western Pacific marine clupeoid fish, Spratelloides atrofasciatus Schultz, 1943, previously regarded as a synonym of S. gracilis (Temminck and Schlegel, 1846), is redescribed here as a valid species on the basis of the holotype and 115 non-type specimens collected from the Ryukyu Islands. Both S. atrofasciatus and S. gracilis are similar chiefly in having a midlateral band that does not fad...

Sardinella sindensis is one of the dominant small pelagic fish of Karachi coast of Pakistan. Investigation on fecundity of sind sardinella was studied from January 2001 to April 2002. A total of 37 ovaries were examined of stages IV-VI (when not running). Mean fecundity ranged from 47521 to 110876 eggs. Log-log relationship between fecundity with total body-length, fish-weight & ovary weight we...

One of the parasite diseases associated with the consumption of raw fish that occurs with some frequency is the anisakiasis, a human disease caused by the accidental ingestion of larval nematodes of the genus Anisakis, family Anisakidae. At the National Reference Centre for Anisakiasis (C.Re.N.A.) from October 2012 to February 2013, a number of 231 bony fish (Trichiuridae, Engraulidae, Scombrid...

 The influence of five pure diets of isonitrogenous and isoenergic with different ratios of Clupeidae fish oil (F) and soybean oil (S) on growth, molting and survival of narrow-clawed crayfish, Astacus leptodactylus, was evaluated during an 8-weeks trial. As soybean oil replaced with fish oil in each treatment, gently. Test diets were inclusive F0/S100, F30/S70, F50/S50, F70/S30 and F100/S0 fis...

Survey of fish larvae abundance, diversity and distribution was carried out in different habitats of Khark and Kharko coralline islands and islets from July 2006 to June 2007 over 12 stations. Khark and Kharko ecosystems are protected areas and wildlife refuges in northern point for fringing coral reefs in Iranian side of the Persian Gulf. This investigation was a part of the national Integrate...

Most fish cannot hear frequencies above 3 kHz, but a few species belonging to the subfamily Alosinae (family Clupeidae) can detect intense ultrasound. The response of adult specimens of the European allis shad (Alosa alosa) to sinusoidal ultrasonic pulses at 70 and 120 kHz is tested. The fish showed an intensity-graded response to the ultrasonic pulses with a response threshold between 161 and ...

The study and research of abundance and diversity variation of fish larva (Ichthyoplankton stages) was done in Gowatr Bay during autumn 2006 - summer 2007. Five stations were selected for sampling, and Bongo-Net with 300µ mesh size was towing from bottom to surface. During of survey, totally 531 larvae belong to 11 families were collected and identified. The mean abundance estimated 12.17 larva...
