A total of 200 moribund rainbow trout with clinical signs of a hyperacute haemorrhagic septicemia were collected from rainbow trout farms in Fars, Kohkiloyeh-Boyer Ahmad and Charmohal-Bakhtiari provinces in the south and southwest of Iran during summer 2002 to winter 2008 for detection of Lactococcus garvieae, the causative agent of lactococcosis. Fish kidney samples were cultured aseptically o...

—We collected and compiled length and weight information from four countries and one commonwealth to develop standard weight (W s ) equations for three amphidromous fish species native to the Caribbean and Gulf of Mexico regions: mountain mullet Agonostomus monticola (N 1⁄4 9,768 individuals, 52 populations), river goby Awaous banana (N 1⁄4 1,847 individuals, 62 populations), and bigmouth sleep...

From January to December 2019, the composition of fish assemblages in Al-Huwyzah marsh was studied various ways based on nature their life-history strategies. In orders assess impact hydrological variations assemblage composition, diversity, and abundance. Water temperature fluctuated from 12°C 33°C July. Salinity varied 1.38 g/l March 3.87 November. Hydrogen ion 7.37 November 8.18 December. Mo...

There is a critical need to simply and reliably monitor brevetoxins routinely in the blood of humans and aquatic animals. We used striped mullet as laboratory test animals to better define the uptake and elimination kinetics of brevetoxin during an aqueous exposure to the brevetoxin-producing dinoflagellate Karenia brevis. Striped mullet were first exposed to sublethal densities of K. brevis (a...

The aim of this study was to investigate changes in the microbiological and physiochemical characteristics in Egyptian salted-fermented fish (Feseikh) during processing, ripening and storage. Isolation of total viable bacteria, Enterobacteriaceae, lipolytic bacteria, proteolytic bacteria, total spore forming bacteria (CFU/g) and Clostridium perfringens (MPN) from fish flesh, fish intestine and ...

Based on the current demand fish as food, marine fishes of Sudan have been arbitrary divided into first, second and third grade fish. Examples these are red emperor (Plectroponus moculates) I, mullet II unicorn (Naso unicornis) III. This subjective grading, need to be evaluated grounds organo-leptic tests, gross chemical body parts analysis inclusion in experimentally designed feeding tests. Th...

Zinc oxide nanoparticles (ZnO NPs) have received great attention due to their optical, physical, and antimicrobial properties. They toxic effect against microbes without any on mammalians cells. are used in several applications including extending the shelf life of food. The study aims determine minimum inhibitory concentrations ZnO NPs different aquaculture fish fungus species storage period. ...

Selenium is an essential micronutrient for humans, and seafood is one of the major selenium sources, as well as red meat, grains, eggs, chicken, liver and garlic. A substantial proportion of the total amount of selenium is present as selenium containing imidazole compound, selenoneine, in the muscles of ocean fish. In order to characterize the selenium content in seafood, the total selenium lev...

Fish eyes and brain are highly susceptible to environmental Hg exposure but this issue is still scarcely investigated, mainly regarding methylmercury (MeHg) accumulation. Yet, Hg levels in fish lens have not been previously examined under field conditions. Total Hg (tHg), MeHg and inorganic Hg (iHg) levels were assessed in the brain, eye wall and lens of the golden grey mullet (Liza aurata) fro...

Trichodinid Ciliophorans are one of the most common and widely dispersed groups of symbionts as parasites of aquatic invertebrate and vertebrate hosts (VAN AS & BASSON, 1989). The taxonomy of Trichodinids is based on the structure and the appearance of the adhesive disc and number and size of its constituents. All of these features can be revealed only by the silver impregnation technique of Kl...
