In Carangidae, Caranx is taxonomically controversial because of slight morphological differences among species, as well as because of its relationship with the genus Carangoides. Cytogenetic data has contributed to taxonomic and phylogenetic classification for some groups of fish. In this study, we examined the chromosomes of Caranx latus, Caranx lugubris, and Carangoides bartholomaei using cla...

Fauna of fur mites of the genus Schizocarpus Trouessart, 1896 (Acariformes: Chirodiscidae) associated with the Eurasian beaver Castor fiber L. (Rodentia: Castoridae) in the beaver farm of Voronezh National Reserve (Russia) was examined. Totally, 16 Schizocarpus spp. were recorded. Among them 11 species were previously described by Dubinina (1964) from the same locality and four following recove...

The relationships between otolith score, a function of increasing stain visibility, and the ratio of alizarin complexone (mg) to fish biomass (g) for 0.1, 0.6 and 7 g black bream Acanthopagrus butcheri show that acceptable marks are produced in all size classes using a stain-to-biomass ratio of 3.3 mg g(-1) following an immersion period of 24 h.

In the present study, Mercury (Hg) accumulation in different tissues of Yellowfin seabream under different Hg concentrations in the medium were investigated. For this, PurPuse 45 fish specimen of the same size (19.2±1.8cm and 134.0±36.1 g) were caught from Musa Estuary, in northwest of the Persian Gulf and transferred to the laboratory. Fish were divided into five different groups of 9 fish ...

C-banding pattern and Ag-NORs on chromosomes of Trechus latus, T pilisensis T pulchellus, and T quadristriatus are presented. T pulchellus has a paracentromeric C-band similar in size on all chromosomes. T latus has euchromatic the X chromosome but all autosomes have a paracentromeric C-positive band. In the karyoty}l' of T quadristriatus the 1st pair of autosomes is euchromatic while the autos...

Yellow finned sea bream (Acanthopagrus arabicus) is a commercially important fish of coastal water Pakistan. It widely consumed by the people within and outside country. Therefore, paper investigates concentration macro-minerals (Ca, K, Mg Na) in its meat gills. The concentrations different elements demonstrated statistically significant difference (P < 0.01) between gills fish. Significantl...

The development of the marine aquaculture industry has led to the generation of significant amounts of fish wastes. Marine farm wastes exert adverse effects on the surrounding area of the cages. On the other hand, wastes of fish and other aquatic animals are regarded as major sources of valuable natural bioactive compounds, including enzymes, proteins, bioactive peptides, oil, amino acids, coll...
