Abstract Ninety days study was conducted in hapas installed earthen ponds. Fish of an average initial weight (220g) were evenly distributed triplicate groups within fifteen hapas. Five experimental diets labeled as T1 (25% CP and NRC recommended amino acid level) control diet, T2 (with 2% low protein 5% supplementation), T3 10% T4 4% supplementation) T5 20% prepared. fed with @3% their body twi...

Sea bass (Dicentrarchus labrax L., 1758) production in Turkey has increased significantly recent years, especially for export to EU countries. This study determined inorganic arsenic (iAs) levels by measuring total (AsT) muscle tissues sampled from sea fished and farmed (both earthen ponds cages) Güllük Bay within the borders of Muğla province. The also conducted a risk assessment consumption c...

As a first step in assessing the viability of periphyton-based fish production in South Asian pond aquaculture systems, the effects of artificial substrates on development of periphyton and on water quality were evaluated. Earthen ponds (10 × 7.5 m) were provided with an artificial substrate constructed from poles of either bamboo, kanchi or hizol tree branches (1.0 m artificial substrate per m...

Abstract Increasing frequency and severity of droughts have motivated natural resource managers to mitigate harmful ecological hydrological effects drought, but drought mitigation is an emerging science evaluating its effectiveness difficult. We examined ecohydrological responses actions aimed at conserving populations the Columbia spotted frog (Rana luteiventris) in a semi-arid valley Nevada, ...

Angling for Muskellunge Esox masquinongy has become widespread and increasingly popular. Management strategies include high minimum harvest lengths (>1016mm), closed seasons, catch-and-release regulations. Due to these angler behaviors, up 97% of caught are released, anglers assume fish survive be again in the future. Previous research on mortality suggested relatively low rates (0%-5%). Howeve...

In Bangladesh, fish provide over 60% of animal-source food with 56.2% this coming from aquaculture produced predominantly in rural freshwater ponds. Increasing demand for products is driving intensification and resulting higher disease prevalence, posing a risk to security. Biosecurity often absent practices Bangladesh antibiotics are commonly used treat prevent outbreaks. Antibiotics administe...
