Chronic thermal stress affects growth, liver morphology and molecular responses but allows recovery at optimal temperature in juvenile zebrafish (Danio rerio)

Journal of Fish Biology, EarlyView.
Abstract Climate‐driven aquatic heatwaves pose an increasing threat to fish populations by inducing prolonged thermal stress. However, the resilience of teleosts to chronic heat exposure and their capacity for recovery remains poorly understood. This study investigated the effects of chronic high‐temperature exposure on juvenile zebrafish (Danio rerio).

Take my breath away: Defining the oxygen saturation threshold for fish cortisol stress response

Journal of Fish Biology, EarlyView.
Abstract Human activities are affecting the number, size and severity of hypoxic zones in aquatic ecosystems. As oxygen is one of the most important abiotic factors affecting fish biology, exposure to low levels of dissolved oxygen may lead to a reduction in fitness.

Acute toxicity of Euphorbia kamerunica on Oreochromis niloticus

Ecotoxicology and Environmental Safety, 2005
A series of static short-term bioassays was conducted to assess the acute toxicity of the plant Euphorbia kamerunica on the fingerlings of Oreochromis niloticus. The 96-h LC(50) was computed using two methods: probit analysis and the arithmetic graphic method. The overall mean value of 0.023 +/- 0.002 g/L was obtained.
