The aim of the present study was shedding light on disease factors underlying mortality event among common carps inhabiting Hirfanlı Dam Lake in Türkiye spring year 2021. For this purpose various parasitological, bacteriological and virological research techniques were employed. Five parasite genera, Dactylogyrus spp., Myxobolus Eimeria Trichodina Diplostomum spp. isolated from 13 carps. opport...

The effect of phenol on haematological components of Indian major carps, Catla catla, Labeo rohita and Cirrhinus mrigala were observed. After exposure to sublethal concentrations of 5.17 mg l(-1), 6.06 mg l(-1) and 6.99 mg l(-1), the number of red blood cells, haemoglobin content and packed cell volume all decreased but the glucose level increased. The order of decrease in the haematological co...

In the context of worldwide water shortage, environmental flow is key to alleviating negative impact reservoir operation. reality, there exists a range for stream suitable survival and reproduction aquatic organisms. However, most current studies set it fixed value, which leads unreasonable resource allocations. this study, we proposed fuzzy representation by using theory ecological hydraulic r...

An appropriate environmental flow (AEF) is one of the necessary conditions for fish spawning. The operation cascade reservoirs in lower reaches Jinsha River has changed discharge process downstream, which turn directly affected spawning habitat fishes. Determining how to quantitatively evaluate impact different outflows from Xiangjiaba Reservoir on four major Chinese carp species downstream are...

Abstract The construction and utilization of the hydro-junctions would change water flow affect hydrologic process required for survival reproduction aquatic organism in river basin. To investigate influence Jiepai (JP) Bazizui hydro-junction (BZZ) on Xinjiang River coordinate benefits between power generation downstream ecological protection four major Chinese carps (FMCC), a one-dimensional h...

Bigheaded carps (bighead carp, Hypophthalmichthys molitrix, and silver nobilis) their hybrids play an important ecological economic role in original habitat, while introduced stocks may pose serious risks. To address questions about the persistence invasiveness of these fish, we need to better understand population structures. The genetic structures bigheaded carp populations inhabiting Lake Ba...

Caudal neurosecretory system is an additional neuroendocrine system found in fishes. Great variation has been observed among different groups of fishes, so far its organization is concerned. Much work has been undertaken on the caudal neurosecretory system of elasmobranchs and teleosts. large size scattered Dahlgren cells in the posterior end of spinal cord, corresponding to last few vertebrae,...

Biomineralization is a widely dispersed and highly regulated but poorly understood process by which organisms precipitate minerals from a wide variety of elements [1]. For many years, it has been hypothesized that the biological precipitation of carbonates is catalyzed by and organized on an extracellular organic matrix containing a suite of proteins, lipids, and polysaccharides [2, 3]. The str...
