Reproduction Of Black Drum, Pogonias Cromis, From The Chesapeake Bay Region, Brian K. Wells, Cynthia M. Jones
Reproduction Of Black Drum, Pogonias Cromis, From The Chesapeake Bay Region, Brian K. Wells, Cynthia M. Jones
Virginia Journal of Science
Ovaries of black drum, Pogonias cromis, collected from the Chesapeake Bay region in 1992, were used to describe reproductive strategy and fecundity. Histological examination showed that black drum spawn in the Chesapeake Bay region from April through early June. Distributions of oocyte diameter showed distinct oocyte-developmental groups indicating that Chesapeake Bay black drum are group-synchronous batch spawners. Female black drum are extremely fecund ranging from 414,000 to 3,736,000 hydrated oocytes (mean = 1,389,000) per batch with a spawning periodicity of 3.8 days. Estimates of spawning strategy, spawning periodicity, and batch fecundity for black drum from the Chesapeake Bay region …
Occurrence And Effects Of Diplostomum Sp. Infection In Eyes Of Acanthobrama Marmid In Keban Dam Lake, Elazığ, Turkey, Mustafa Dörücü, N. Di̇lsi̇z, M. C. James Grabbe
Occurrence And Effects Of Diplostomum Sp. Infection In Eyes Of Acanthobrama Marmid In Keban Dam Lake, Elazığ, Turkey, Mustafa Dörücü, N. Di̇lsi̇z, M. C. James Grabbe
Turkish Journal of Veterinary & Animal Sciences
Infection with the parasite Diplostomum sp. can lead to severe ocular pathology and may result in host mortalities in commercial fish farming. Here we show that such infection is rife in a major lake used for fishing in Turkey. In a study of Acanthobrama marmid fish in Keban Dam Lake, Elazığ, Turkey, we found the infection period was normally between May and September each year, and that the prevalence and abundance of eye lens parasites reached a maximum in September. Typical results of metacercariae occurrence in the fish eye included exophthalmia, local haemorrhage and lens cataract. There was a significant …
The Application Of Hypoxanthine Activity As A Quality Indicator Of Cold Stored Fish Burgers, Sühendan Mol, Nuray Erkan, Candan Varlik
The Application Of Hypoxanthine Activity As A Quality Indicator Of Cold Stored Fish Burgers, Sühendan Mol, Nuray Erkan, Candan Varlik
Turkish Journal of Veterinary & Animal Sciences
Seafoods are very perishable, and many different methods are used for the determination of their quality. Sensory and hypoxanthine values of cold stored trout burgers, which we prepared, were determined during a 28-day period. Burgers spoiled after the 21st day of storage. The TVB-N values were still very low when the burgers spoiled and the pH values decreased during their storage. Therefore total volatile bases nitrogen and pH analyses were not useful for the determination of the quality of trout burgers. There was a negative correlation between the sensory and the hypoxanthine values during the storage period. Thus, hypoxanthine analysis …

Isolation And Identification Of Vibrio Parahaemolyticus In Some Fish Species And Clams (Venus Gallina), Ayşegül Aydin, Ece Soyutemi̇z
Turkish Journal of Veterinary & Animal Sciences
This study was performed to establish techniques used in the isolation and identification of Vibrio parahaemolyticus and investigate the presence of V. parahaemolyticus in fish and clams. Between June 1998 and June 2000, a total of 46 fish samples including 14 anchovies, 12 whiting, 10 horse mackerel and 10 sardines collected from fish markets in Bursa and a total of 70 clam samples collected from shellfish stations in Sakarya and Kocaeli districts were tested for V. parahaemolyticus. Fish samples were found to be free of V. parahaemolyticus. It was detected that total isolation from clams was 10 (14.3%). All the …
Cu, Zn, Pb And Cd Content In Some Fish Species Caught In The Gulf Of Antalya, Meltem Yazkan, Feramuz Özdemi̇r, Muharrem Gölükcü
Cu, Zn, Pb And Cd Content In Some Fish Species Caught In The Gulf Of Antalya, Meltem Yazkan, Feramuz Özdemi̇r, Muharrem Gölükcü
Turkish Journal of Veterinary & Animal Sciences
In this study Cu, Zn, Pb and Cd contents were analyzed in liver and muscle tissues of ten fish species (Mullus barbatus, Mugil cephalus, Trachurus trachurus, Pagellus acarne, Dicentrarchus labrax, Sparus auratus, Sardinella aurita, Boops boops, Scomber japonicus, Solea solea) caught in the Gulf of Antalya in January, February and March 2000. Cu and Zn contents were found to be 0.51-3.66 mg/kg and 3.17-11.36 mg/kg in fish muscles and 0.83-4.44 mg/kg and 3.97-15.14 mg/kg in liver tissue respectively. Pb and Cd, important heavy metals for human health, were found at levels of 0.00-2.05 mg/kg and 0.00-0.13 mg/kg in fish muscle …
