Abstract:
... Burst swimming velocity (Ubᵤᵣₛₜ) was compared between wild and hatchery-reared chum salmon fry. In the hatchery-reared fry, Ubᵤᵣₛₜ was significantly correlated with the condition factor, but not with the body mass and fork length. In the wild-reared fry, on the other hand, Ubᵤᵣₛₜ ranged widely and did not correlate with condition factor. These suggest that well-balanced growth under satisfactory n ...

Abstract:
... All-male tilapia stocks are widely used by farmers to supply both domestic and international markets with homogenous, large sized fish (500 g+). While a number of strategies are possible, hormonal treatment of fry with 17α-methyltestosterone (MT) is the most common method used by commercial farmers due to its low cost and ease of application. However, contrasting to its current widespread use, the ...

Abstract:
... Environmental enrichment is a promising strategy to improve the welfare of fish in captivity. However, the utilization of enrichment in aquaculture is still infrequent, maybe because there is a paucity of knowledge about how its effects depend on factors such as fish species, developmental stage, social environment or the type and extent of enrichment. In this study, we evaluated the effects of ph ...

In particular, understanding these impacts in species caught as bycatch that are released after capture can predict their “post‐release” fate and aid in management plans. Although well studied in several species, capture‐stress is nonetheless frequently assessed without considering putat ...
