The results obtained using morphometric variables which describe fin ray regeneration patterns are reported for individual fin ray amputations in the goldfish (Carassius auratus) and zebrafish (Brachydanio rerio). Classical and updated experiments are compared to verify previous morphogenetic models of cell tractions (Oster et al. 1983) or epidermis-mesenchyme induction (Saunders et al. 1959) a...

In the present work Trichodina reticulata and T. nobilis (Ciliophora: Trichodinidae) are morphologically characterised from ornamental freshwater fish culture in the State of Santa Catarina, Brazil. The prevalence of infection and a list of comparative measurements are discussed. We examined "southern platyfish" Xiphophorus maculatus (n = 35), "goldfish" Carassius auratus (n = 31), "guppy" Poec...

polybrominated diphenyl ethers (pbdes) have been widely used in many products as flameretardants, which resulted in their release into the environment. little is known about the impact of coexisting pbdes on organisms. in this study, the in vivo effects of bde-47 and bde-99 on a suite of biomarkers, acetyl cholinesterase (ache), ethoxyresorufin-o-deethylase (erod), glutathione-s-transferase (gs...

Fermented soybean meal (FSM) is an important feed material that can replace fish to solve the shortage of animal protein. To improve utilization FSM, we optimized co-fermentation conditions using Bacillus subtilis and Enterococcus faecium studied effects replacing with different proportions FSM on serum antioxidant indices gut microbiota (GM) composition crucian carp (Carassius auratus). Our re...

This study was carried out in the inland waters of Muğla Basin between 2018-2019. As a result field studies and literature, it determined that there were 36 species fish belonging to 17 families (Anguillidae, Atherinidae, Cobitidae, Leuciscidae, Cyprinidae, Gobionidae, Nemacheilidae, Aphaniidae, Poeciliidae, Blenniidae, Centrarchidae, Cichlidae, Gobiidae, Moronidae, Mugilidae, Salmonidae, Silur...
