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 gastrointestinal (GI) microbiome in fish plays significant roles health and disease resistance. This investigation was accomplished to enumerate, characterize identify the potential probiotic bacteria from three Indian Major Carps (IMCs), viz., rohu (Labeo rohita), catla (Catla catla) mrigal (Cirrhinus mrigala) using culture dependent methods. Altogether, 105 pathogen-inhibitory (out of 121...

A simple method has been developed for the isolation of Acid Soluble Collagen (ASC) and Pepsin Digestible Collagen (PDC) from the skin of Albacore tuna (Thunnus alalunga), Dog shark (Scoliodon sorrakowah), and one among Indian Major Carps ie, Rohu (Labeo rohita). Biochemical characterization of the collagen extracted was carried out. On wet weight basis the yields of ASC and PDC from shark skin...

Bioenergetics and food web models are tools available for understanding projecting the impacts of aquatic species invasions on structure energy allocation an ecosystem. However, uncertainty is inherent in modeling impact invasive novel ecosystems as assumptions must be made about physiological responses to environments interactions with existing (native non-native) species. Here we use four maj...

The successful fish upstream movement through a dam/gate is closely associated with the hydraulic conditions of fishway. To improve passage efficiency, this study investigated swimming behaviors juvenile grass carp, representative four major Chinese carps, under characteristic designed vertical slot fishway model. impacts different discharges and baffle lead angles on test were analyzed, select...

Nonindigenous bigheaded carps (Bighead Carp Hypophthalmichthys nobilis and Silver Carp H. molitrix; hereafter, “Asian carps” [AC]) threaten to invade and disrupt food webs and fisheries in the Laurentian Great Lakes through their high consumption of plankton. To quantify the potential effects of AC on the food web in Lake *Corresponding author: [email protected] Received December 6, 2014; accep...

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...
