Increase in water temperature due to anthropogenic and climatic changes is expected to affect physiological functions of fish. In this study, we determined high temperature tolerance (CTmax) of a common aquacultured Indian major carp, rohu, Labeo rohita fingerlings (15.96 ± 0.72 g BW, 11.56 ± 0.42 c...

Temperature is considered as an important environmental factor, and the increasing water temperature resulting from global warming is a great concern. The present study was conducted to examine the effects of elevated water temperature on growth, hemato-biochemical parameters in Nile tilapia, Oreoch...

Temperature is among the critical determinants of the physiology of fishes and other heterotherms throughout the life history. Temperatures outside of the optimal range distress embryonic and larval development with untoward consequences later in life. To understand the effect of high temperature on...

Water temperature alone can affect the growth, metabolic rates and physiological responses of aquatic organisms. Our earlier study reported that higher temperature affects cellular and hemato-biochemical responses in rohu, Labeo rohita. In this backdrop, the present study assessed the effect of high...

Microplastic pollution is drastically increasing in aquatic ecosystems and it is assumed that different sizes of microplastics have diverse impacts on the physiology of aquatic organisms. Therefore, this study was intended to examine the ingestion and size specific effects of polyamide microplastic ...

Salinity intrusion in coastal areas due to climate change is alarming. In this study, the effects of salinity on embryonic and larval development of striped catfish ( Pangasianodon hypophthalmus ) were studied experimentally. Embryos and larvae were exposed to seven salinity treatments (0, 2, 4, 6, ...

Experiencing the seasonal variation and rapid global warming in the tropical climate is a common phenomenon which challenged the aquatic organisms to adapt the physiology and behavior. To investigate the effect of high-temperature acclimation, we selected Indian major carp, rohu (Labeo rohita), a co...

Nutrition plays an important role in influencing reproductive events spanning from puberty to gametogenesis in all vertebrates, including fish. To know the effects of probiotics on gonadal maturation, expression of genes representing kisspeptin (kiss2), kisspeptin receptor (kiss2r) GnRH (gnrh1, gnrh...

Histoarchitecture effect of cypermethrin was investigated in the gills and liver of freshwater catfish, Pangasianodon hypophthalmus (weight 60-70g) over an exposure period of 96 h as an endpoint of toxicity. The fish were exposed to five acute concentrations (0.00ml/L, 0.025ml/L, 0.050ml/L, 0.075ml/...

The study was carried out from November, 2014 to February, 2015 with the objective of isolating Aeromonas hydrophila an important fish pathogen from infected air-breathing catfish Magur (Clarias batrachus) in Mymensingh district. Quantitative study of the isolated bacteria from infected C. batrachus...

Histoarchitecture effect of cypermethrin (pyrethroids) was investigated in the ovary of Stinging catfish, Shing (Heteropneustes fossilis) over a 96 h exposure period as an endpoint of toxicity. The fish were exposed to five acute concentrations (0.00ml/L, 0.025ml/L, 0.050ml/L, 0.075ml/L and 0.10ml/L...

The study was carried out to identify the parasite and causative diseases on cage reared tilapia at Bakerganj upazila, Barisal district. The infected tilapia fishes were collected from the cages and brought to the laboratory to find out signs, symptoms and infection area on the fish body. Physico-ch...

Global warming is expected to affect the aquatic ecosystem and aquaculture industry. In the current experiment, we have observed growth and water quality of Indian major carp mrigal (Cirrhinus mrigala) exposed to three different temperature regimes, such as 30, 33 and 36°C representing T1, T2 and T3...
