A reproductive biology study of Labeo dero reveals a July breeding peak with female GSI reaching 14.9 %. Induced breeding trials establish optimal doses of 6 mg kg−1 (♀) and 3 mg kg−1 (♂) carp pituitary extract (94.7 % spawning) and 0.6 mL kg−1 (♀) and 0.3 mL kg−1 (♂) Ovuhom (82.3 % spawning).

PHENOTYPIC DIVERGENCE BETWEEN HATCHERY PINK AND COHO SALMON AND THEIR WILD COUNTERPARTS
Interbreeding between hatchery-reared and wild salmon raises concerns that hatchery fish may increase the frequency of maladapted alleles in wild populations, yet divergence between hatchery populations and their original sources remains poorly ...

Differences in antipredator behaviour between wild and hatchery-reared juvenile Atlantic salmon (Salmo salar) [PDF]
Captive rearing may elicit environmental or genetically-based changes to salmonid antipredator behaviour, which may reduce its survival when released into the wild.

This study examined variations in the egg size of wild‐caught and captive broodstock (created from the direct offspring of wild‐caught) brown trout (Salmo trutta) from three peri‐Alpine lakes (Lake Constance, Lake Lucerne and Lake Zurich). It showed that there was lake‐specific variation in egg size between the two groups of trout.

Fish predation causes significant Greenshell mussel losses in New Zealand. Experimental caging methods found losses due to predation up to 93% in juveniles (25 – 34 mm SL) over 67 days. However, the overall contribution of predation at other production stages remains unclear.

Reintroduction is an important tool for the recovery of imperiled species. For threatened Pacific salmonids (Oncorhynchus spp.) species, hatchery‐origin (HOR) individuals from a nearby source are often used to reestablish populations in vacant ...

The impacts of biological invasions
ABSTRACT The Anthropocene is characterised by a continuous human‐mediated reshuffling of the distributions of species globally. Both intentional and unintentional introductions have resulted in numerous species being translocated beyond their native ranges, often leading to their establishment and subsequent spread – a process referred to as biological
