The mechanisms that can contribute in the fish movement strategies and the associated behaviour can be complex and related to the physiology, genetic and ecology of each species. In the case of the brown trout (Salmo trutta), in recent research works, individual differences in mobility have been observed in a population living in a high mountain river reach (Pyrenees, NE Spain). The population ...

The study was aimed at analysing body size in relation to form of gonad maturation (amount of mature germ cells) in 329 under-yearling sea trout males. The fish, aged 7 months, were caught in late October-early November in 3 streams located in north-western Poland. Each stream supported fish belonging to a different sib group. Standard histological techniques and a computer image analysis progr...

In the present report, an efficient method for isolating multiple cytosolic forms of glutathione S-transferases from liver and kidney cytosolic samples of two salmonid species (brown trout and Atlantic salmon) is described, and some of the multiple properties of these enzymes are presented. Glutathione S-transferases were partially purified by low-pressure affinity chromatography on a column wi...

The taxonomic composition of egg-associated microbial communities can play a crucial role in the development of fish embryos. In response, hosts increasingly influence the composition of their associated microbial communities during embryogenesis, as concluded from recent field studies and laboratory experiments. However, little is known about the taxonomic composition and the diversity of egg-...

Günümüzde hızla değişen ve gelişen rekabet ortamı, gastronomi alanında birçok yeni akımı ortaya çıkarmıştır. Gastronomide akımlar incelendiğinde moleküler uygulamaları yaygın olarak karşımıza çıkmaktadır. Bu çalışma kapsamında anlayışı benimsenerek taş alası balığına farklı pişirme tekniklerinin uygulanması reçete edilmesi hedeflenmiştir. Çalışmada tekniklerinden tütsüleme, sous-vide küreleme t...

    The length-weight relationship, age, growth parameters, sex ratio, mortality and exploitation rate of Salmo trutta fario were determined in Lar dam. The sex ratio (male: female) was 1:1.84 which differed significantly from the expected 1:1. The length-weight regression was (females) and (males) indicating a negative allometric growth for both sexes. Growth parameters were estimated as L∞ = ...

The objectives of this research were, first, to determine the concentrations certain heavy metals in edible tissue wild brown trout (Salmo trutta trutta) from two different rivers located Abruzzi region (Italy), and then, investigate levels variation vitellogenin (VTG) associated with presence metalloestrogens. VTG is an effective indicator for endocrine disturbance, increase male fish widely e...
