Journal of Fish Biology, EarlyView.Abstract Environmental DNA (eDNA) biodiversity surveys have the power to transform the detection of species in natural environments, which is crucial for the conservation and management of freshwater, estuarine and marine environments. Globally, eDNA‐based analyses have increased significantly, with fishes being the most widely studied aquatic ...

Journal of Fish Biology, EarlyView.Abstract Hatchery‐reared, domesticated strains of common carp Cyprinus carpio (‘carp’) are regularly used to enhance angler catch rates in many catch‐and‐release (C&R) lentic fisheries. These carp are usually selected for specific traits (e.g. stress resilience, high probability of angling capture) and are often stocked at relatively small sizes into ...

Boat electrofishing survey of the Waimapu and Kopurererua streams, Bay of Plenty, Waitara River, and a pond at Mokoia, Taranaki [PDF]
, 2005 We conducted boat electrofishing surveys at four sites to establish the presence of, and to remove, koi carp (Cyprinus carpio). We fished the lower Waimapu Stream, Bay of Plenty, on 15 April and 14 June 2005, and the adjacent Kopurererua Stream on 15 ...

Fish welfare in a changing world: New developments and current challenges
Journal of Fish Biology, EarlyView.Abstract The welfare of non‐human animals is central to ethical discussions on animal use, with increasing attention to fish welfare across research, aquaria, aquaculture, and fisheries. This paper reviews current theoretical approaches to animal welfare and recent advances in defining and assessing fish welfare since the seminal paper by Huntingford ...

Improving spine‐based age estimation in centrarchid fishes using otolith‐derived training sets
Journal of Fish Biology, EarlyView.Abstract Nonlethal age determination is a priority in fish biology contexts where sacrifice is restricted, but estimates derived from nonlethally attainable structures tend to suffer from poor precision and accuracy relative to necessarily lethal, otolith‐derived estimates.
