Spatial cognition in zebrafish: The role of strain and rearing environment

Two strains of zebrafish, WIK and a second-generation wild strain were reared in either a structurally simple or complex environment and compared in their ability to locate a food reward in a five-chambered maze. There was a significant interaction within...

Insensitivity to reward shifts in zebrafish (Danio rerio) and implications for assessing affective states

Theory and empirical findings predict that individuals in a negative affective state are more sensitive to unexpected reward loss and less sensitive to unexpected reward gain compared to individuals in a neutral or positive affective state. We explore the use...

UV deprivation influences social UV preference in juvenile sticklebacks

Social aggregations occur in many different animal taxa and mainly result from non-random assortment. Investigating factors that shape and maintain the composition of social aggregations are among others a main topic for understanding ecological speciation processes. Aggregation decisions are mediated...

Illu-shoal choice: An exploration of different means for enrichment of captive zebrafish

Fish of any variety are nowadays being kept captive for several purposes, from recreational to alimentary to research. It is possible that we humans often underestimate or misunderstand the basic, natural needs of the species we use for our purposes....

Impacts of temperature on the growth, feed utilization, stress, and hemato-immune responses of cherry salmon (Oncorhynchus masou)

Cherry salmon (Oncorhynchus masou) hold commercial value in aquaculture, and there is a need for controlled laboratory studies to isolate the specific effects of temperature on their growth, feeding, and well-being. We examined the effects of different temperatures (10 °C,...

Euthanasia complications in non-domestic species

There are very few studies describing euthanasia complications in non-domestic species. The goal of this study was to survey veterinarians to determine what complications may commonly occur during the euthanasia of non-domestic species. An online survey was sent to seven...

Temperature and dissolved oxygen lead to behavior and respiration changes in juvenile largemouth bass (Micropterus salmoides) during transport

The study aimed to investigate the effects of temperature and dissolved oxygen on juvenile largemouth bass during transportation. The experiment involved four temperature groups: 20, 15, 10, and 5 °C. We analyzed the effects of acute and uniform cooling on...

Fish welfare in aquaculture: Physiological and immunological activities for diets, social and spatial stress on mediterranean aqua cultured species

Welfare assessment currently is less well-characterized for aquatic animals and the classical methodologies used for terrestrial animals are not adequate to improve our knowledge about fish well-being. Among different approaches, the status of organism responses can be carried out using...
