The influence of environmental variables (oceanographic and climatic) on the catch rates striped red mullet (Mullus surmuletus) by artisanal fishery was investigated using different time series models (Dynamic Factorial Analyses; Min-Max Analyses Generalized Least Square models). Climatic oceanographic survey data were collected at areas Portuguese coast (Northwestern, Southwestern South-Algarv...

The formulator of aquatic diets is part a continuous search for alternative protein sources instead depreciated fish meal. utilization zooplankton as feed ingredient an interesting trend due to their high-quality content and abundance essential nutrients. current study aims investigate the effects partial total replacement meal (FM) by Dahpnia magna (DMM) on growth performance, utilization, his...

Salt marshes are under increasing anthropogenic pressures that have been reported to affect the diet of fish (e.g., change in prey composition and availability), eventually resulting alterations their nursery function. Most studies Europe based on gut content analysis, which only reflect a small proportion salt marshes, do not necessarily long-term disturbances. In this study, we investigated i...

The present study reports on the main parasites found in mullet (Mugil platanus) and their prevalence throughout the year on Uruguayan coasts of the River Plate. The following parasites were found: Ichthyobodo necator, Trichodina sp., Scyphidia sp, Gyrodactylus sp., Dactylogyrus sp., Metamicrocotyla sp., Dicrogaster sp., Phagicola sp. and “Scolex polymorphus”. The viability of mullet (Mugil pla...

ichthyozoonotic mycobacterium spp. poses health risks both to fish and humans. in this study, the presence of ichthyozoonotic mycobacterium spp. was investigated in red mullet (mullus barbatus barbatus) and surmullet (mullus surmuletus), widely caught species in the mediterranean and the aegean sea. a total of 208 fish samples, provided from fishermen of mersin province (turkey) were studied. u...

A full-length cDNA encoding a dopamine receptor (DA-R) was obtained from the pituitary of tilapia (ta). This cDNA encodes a protein of 469 amino acids that exhibits the typical arrangement of GPCR. The taDA-R shows high similarity to the DA-Rs of mullet and fugu, and over 70% similarity to Xenopus, mouse and turkey D2 DA-Rs. Northern blot analysis revealed transcript for a single transcript in ...

Molecular polymorphisms (allozyme and amplified fragment length polymorphisms (AFLP)) were investigated in the mullet specie’s Liza ramada and Liza saliens to determine levels of genetic variability and assess possible correlations between the population genetic structure and the specie’s adaptability to shallow water environments. The thinlipped (L. ramada) and the sharpnose (L. saliens) mulle...
