Tipping the Scales Using Cryopreservation: Modelling the Genetic Value and Management Potential of Integrated Cryopreservation for Threatened Ex‐Situ Pupfish Populations

open access: yesAnimal Conservation, EarlyView.
This graphical abstract depicts the number of additional fish that would be required to achieve 90% genetic diversity for endangered pupfish species housed in EAZA collections, with or without the use of cryopreserved material. ABSTRACT Zoos and aquaria must retain genetic diversity for the species they house if the populations are to remain viable ...

Boat electrofishing survey of the Waimapu and Kopurererua streams, Bay of Plenty, Waitara River, and a pond at Mokoia, Taranaki [PDF]

open access: yes, 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 ...

Oral vaccination with recombinant Lactobacillus casei expressing Aha1 fused with CTB as an adjuvant against Aeromonas veronii in common carp (Cyprinus carpio)

open access: yesMicrobial Cell Factories, 2022
Aeromonas veronii (A. veronii) is a pathogenic that can infect human, animal and aquatic organisms, in which poses a huge threat to the health of many aquatic organisms such as Cyprinus carpio. In this study, Lactobacillus casei (L.

Behavioural Diversity of Fishes: Concepts, Drivers and Its Role in Conservation and Management

open access: yesFish and Fisheries, EarlyView.
ABSTRACT Human activity has altered nearly all ecosystems on Earth, contributing to substantial biodiversity loss across taxonomic, genetic and functional dimensions, from the intraspecific to the ecosystem scale. Yet some components of biodiversity remain hidden or underappreciated, including behavioural diversity.

Capture Probability and Effects of Bait Type on Learning Behavior in an Unexploited Population of Northern Pike (Esox lucius)

open access: yesFisheries Management and Ecology, EarlyView.
ABSTRACT Changes in angling response were studied over a period of three years in a natural, previously unfished population of northern pike. Standardized angling sessions took place during two weeks in spring and autumn with three bait types: bright‐ and natural‐colored soft plastic baits and a dead baitfish.

Boat electrofishing survey of Apata Pond and Lake McLaren [PDF]

open access: yes, 2004
We used New Zealand’s first successful electrofishing boat to catch koi carp (Cyprinus carpio haemaotopterus; Zhou et al. 2003) and rudd (Scardinius erythophthalmus) at two sites in the Bay of Plenty, North Island, New Zealand.

Hybridization between Native Barbless Carp (Cyprinus pellegrini) and Introduced Common Carp (C. carpio) in Xingyun Lake, China

open access: yes, 2012
Hybridization with introduced fish species is an important threat to native fish species. Here we investigated hybridization between native barbless carp (Cyprinus pellegrini) and introduced common carp (C.
