Mycotoxins are difficult to monitor continuously, and a tool to assess the risk would help to judge if there is a particular risk due to the inclusion of certain feed ingredients. For this, the toxin contents of 97 commercial fish feeds have been estimated, and the most prominent toxins in fish feed are calculated to be deoxynivalenol, zearalenone, fumonisins and enniatins. These pose a risk to fish well-being, as can be calculated by the Bayesian models for determining the critical concentrations 5% (CC5) for the different toxins. Besides fishmeal, wheat, soybean products and corn are regularly used as fish feed ingredients. The calculated scenarios show that fish are at high risk of toxin contamination if feed ingredients of low quality are chosen for feed production. Due to this, specific maximum allowable levels for several mycotoxins in fish feeds should be established.

The Mediterranean Sea is home to a wide variety of fish species that exhibit carnivorous behavior, particularly during the juvenile to pre-adult stages. This study aimed to compare the tongue morphology of four Mediterranean carnivorous fish species: the dusky grouper fish (Epinephelus marginatus), John Dory fish (Zeus faber), squirrelfish (Holocentrus spp.), and red lionfish (Pterois volitans).

Traditional fish survey methods are often impractical or invasive in these habitats. This study presents a lightweight, low-cost, T-shaped remote underwater video (RUV) system optimized for fish monitoring in small, high-altitude streams of the European Alps.

Floodplains support a diverse cichlid community, yet the trophic ecology of these species is not well understood. This study investigated the dietary niches and trophic guilds of cichlid species in the Cross River floodplain. A total of 480 fish samples from eight cichlid species were collected from three locations (Itu, Obubra, Ikom) over 6 months (October 2019-March 2020).

This review examines the chemical and ecological interactions between filter-feeding mussels and the green macroalga Ulva prolifera in integrated multi-trophic aquaculture (IMTA) systems. Mussels are crucial for nutrient recycling, as they filter water and release bioavailable compounds such as ammonium (NH), urea (CO(NH)), and dissolved organic matter (DOM). These compounds promote Ulva growth and enhance microbial activity.

This study evaluated how dietary black seed oil (Nigella sativa L.) against the diazinon waterborne toxicity on Nile tilapia (Oreochromis niloticus), focusing on growth performance, hematological and biochemical parameters as well as oxidative stress markers and histological changes. A 40-day feeding trial was carried out using four experimental groups: Group 1 (control group), Group 2 (N.
