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

Animal 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 ...

Oocyte structure and ultrastructure in the Mexican silverside fish Chirostoma humboldtianum (Atheriniformes: Atherinopsidae)

Revista de Biología Tropical, 2008
the structural and ultrastructural features of gonads from endemic Mexican fish have received scarce attention. This study describes the histological and ultrastructural characteristics of the oocyte in Chirostoma humboldtianum. The ovary is asynchronic,

Characterization of C-C chemokine receptor subfamily in teleost fish

, 2009
Chemokines and their receptors play important roles in nervous and immune systems. Little information, however, exists concerning this gene family in teleost fish. In the present Study, 17 C-C chemokine receptors genes were identified from Danio rerio, 9

Understanding the Type 2 Immunity: An Evolving View Beyond Allergic Diseases

Allergy, EarlyView.
ABSTRACT Type 2 (T2) immunity is classically associated with defense against helminths and environmental threats, from a physiological perspective, and with allergies and eosinophilic inflammatory diseases, in a pathological sense. However, growing evidence reveals that T2 pathways also support other essential homeostatic functions, including tissue ...

Evolution of Bony Fish: Without a Cryptic Sarcopterygian, It May Have Evolved Actinopterygians into Terrestrial Animals

Diversity
The evolution of Osteichthyes began with a split into two major lineages: Sarcopterygii (lobe-finned fishes) and Actinopterygii (ray-finned fishes).

Phylogenetic and ecological duality in the otoliths of Sciaenidae

Cladistics, EarlyView.
Abstract Teleost fishes have evolved taxon‐specific otoliths that vary greatly in size and shape and are primarily involved in hearing and balance. This study identifies the main drivers of otolith shape disparity in Sciaenidae, a clade of sound‐producing bony fishes, using three‐dimensional geometric morphometrics (3DGM).

Distinct sex differences in the production of steroids and neuropeptides in the adult zebrafish brain–pituitary–gonadal axis

FACETS
Zebrafish are valuable models for studies of human disease, environmental toxicology, and reproductive biology. However, sex differences in hormone production are rarely examined, despite gene mutation studies showing differential effects in females and ...

Estimating Total Post‐Release Mortality in a Boat‐Based Recreational Fishery

Fisheries Management and Ecology, EarlyView.
ABSTRACT Catch‐and‐release angling is widespread in marine recreational fisheries resulting from the implementation of enforced minimum legal sizes and increasing uptake of voluntary release. This makes recreational fisheries selective, with high release rates in certain cases.

Growth and Overfishing Indicators Applied to the Protandrous Hermaphrodite Fat Snook (Centropomus parallelus) in the South Atlantic

Fisheries Management and Ecology, EarlyView.
ABSTRACT The fat snook Centropomus parallelus is a protandrous hermaphrodite teleost of artisanal and recreational value in the South Atlantic, vulnerable to fishing pressure and size‐selective gears. We evaluated exploitation status using size and age based overfishing indicators from recreational fishing championships and artisanal landings along the
