The study demonstrates whether the Guanchiche of Vinces rivers presents pathogenic bacteria Vibrio type, which can cause many gastrointestinal diseases. fish were obtained directly from sampling sites, and physiological nutritional status was determined through indicators Hepatosomatic Index (IHS), Gonadosomatic (IGS), Condition Factor (CF), microbiological isolation characterization. Values re...

A 56-day feeding trial was conducted in a flow-through seawater system to investigate the effects of lysophosphatidylcholine (LPC) on growth performance and lipid metabolism turbot. Four experimental diets were prepared, differing only LPC supplementation, namely, 0 (LPC-0, control), 0.1 (LPC-0.1), 0.25 (LPC-0.25), 0.5% (LPC-0.5) dry matter. Each diet randomly fed triplicate tanks. LPC-0.1 LPC-...

Objective: This study was conducted to evaluate the effects of different proportions of marshmallow extract (Althaea officinalis L.) on growth performance and carcass composition of common carp (Cyprinus carpio). Methods: Common carp with an average weight of 37.65 ± 4.40 g were fed for two months with a diet supplemented with marshmallow (A. officinalis) ext...

The toxicity and estrogenicity of a final treated municipal effluent was examined while flowing through a constructed wetland in north-central Texas, USA. Fish data were collected, and a baseline wetland characterization was performed to assess wetland treatment potential for these effluent properties. Vitellogenin (VTG), gonadosomatic index (GSI), hepatosomatic index (HSI), and secondary sexua...

in this study, the effects of dietary intake of different levels of ginger (zingiberofficinale) extract on fingerlings of mesopotamichthys sharpeyi,were investigated. for this purpose, 192 fingerlings (mean weight: 11.67±0.32 g) were randomly distributed in twelve 300 litres fiberglass tanks (16 fish per tank) and fed with commercial diet containing 0% (control group),0.1%, 0. 5% and 1% of etha...

Methods: Common carp with an average weight of 37.65 ± 4.40 g were fed for two months with a diet supplemented with marshmallow (A. officinalis) ext...

The reproductive biology of Mugil liza Valenciennes, 1836 is described as a contribution to an elaborate management programm. A total of 243 specimens (89 males and 154 females) were collected in the Sepetiba Bay in south-eastern Brazil from July/2006 to June/2007. The gonadosomatic index (IG) and the sequential development of the ovaries observed through histological studies suggested that the...

The effect of the number of spawnings on several biochemical components of ovary, hepatopancreas, and haemolymph was investigated. Shrimps of two origins were compared; wild-caught and pond-reared spawners. Individually tagged females were sampled at the end of a production period in a commercial hatchery. Females with multiple spawnings had a higher Ž . gonadosomatic index GSI , increased leve...

In this study, we investigated the beneficial effects of melatonin against benzene-induced liver function impairments in Wistar rats. After 30 days of treatment, it significantly lowered hepatosomatic indices, bilirubin, and hydroxyproline in male and female benzene-treated rats. Even though it did not influence aspartate aminotransferase, melatonin had beneficial effects on alanine aminotransf...

Farmed lumpfish (Cyclopterus lumpus) are commonly used as cleaner fish in the salmonid aquaculture industry, but a knowledge gap exists with regards to their body density. Filling this is of importance, has no swim bladder and thus relies on alternative methods for buoyancy, i.e., density difference between its surroundings. The aims study were measure investigate correlation different operatio...
