Insights into the concept of fish welfare
(Inter-research, 2007-05-04)
Fish welfare issues are predicated on understanding whether fish are sentient beings. Therefore, we analyzed the logic of the methodologies used for studying this attribute. We conclude that empirical science is unable to ...

Challenges in Assessing Fish Welfare
(Inst Laboratory Animal Research, Natl Res Council, 2009-01-01)
Descriptions of feeling states in nonhuman animals have relied on indirect evidence from empirical data. Assumptions that fish do not experience suffering lack evidence and in fact contradict a large body of indirect ...

Welfare in nile tilapia production: Dorsal fin erection as a visual indicator for insensibility
(2021-10-01)
In aquaculture, to ensure animal welfare in pre-slaughter and slaughter stages, it is fundamental that fish are insensible. A method for evaluating fish insensibility is based on visual sensibility indicators (VSI) assessment ...
Juvenile Nile Tilapia Fish Avoid Red Shelters
(2021-01-01)
Shelters are frequently used for fish rearing to improve welfare conditions. In this study, whether Nile tilapia prefers specific shelter colors was evaluated. Thus, fish preference for white, red, blue, green or yellow ...
Influence of stocking density on growth performance and welfare of juvenile tilapia (Oreochromis niloticus) in cages
(Arquivo Brasileiro Medicina Veterinaria Zootecnia, 2017-01-01)
Intensification of tilapia production can cause negative implications on performance and welfare of fishes. Thus, it is essential to determine a correct density for optimal production. This study aimed to evaluate performance ...

(2021-07-01)
We tested whether territorial fish (Nile tilapia) perceive body tactile stimulation as a positive or negative resource. Individual male fish were placed for eight days in an aquarium containing a rectangular PVC frame, ...
