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

open access: yesFisheries 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

Role of NO in arterial vascular function of intertidal fish (Girella laevifrons) and marine fish (Isacia conceptionis)

open access: yesBrazilian Journal of Biology
Previous studies performed in intertidal fish (Girella laevifrons),as well as marine fish (Isacia conceptionis), showed that acetylcholine (ACh) produced contractions mediated by cyclooxygenases that were dependent on the area and potency of contraction ...

Identifying the Drivers of Newfoundland Capelin Recruitment After a Breakdown in the Environment–Recruitment Relationship

open access: yesFisheries Oceanography, EarlyView.
ABSTRACT Environment‐recruitment relationships often break down over time. This can occur because of spurious results from testing numerous environmental variables in the original analyses or from relative changes in the importance of specific environmental drivers over time.

Vascular function in arteries of intertidal fish Girella laevifrons(Kyphosidae)

open access: yesBrazilian Journal of Biology
Preliminary studies showed that dorsal artery contraction mediated by acetylcholine (ACh) is blocked with indomethacin in intertidal fish (Girella laevifrons).

A global perspective on the annual cycles of whimbrels

open access: yesIbis, EarlyView.
Comparative analyses are central to understanding broad‐scale patterns in avian ecology, yet their application is often constrained by fragmented and uneven data availability. Recent advances in tracking technology have generated unprecedented insights into shorebird movements, resulting in numerous studies on single populations or flyways.

Age, growth and sexual dimorphism of the monkeyface prickleback (Cebidichthys violaceus)

open access: yesJournal of Fish Biology, EarlyView.
Abstract Accurate estimates of age, growth and maturation are fundamental to fisheries assessment, conservation and the development of emerging aquaculture species. However, life‐history parameters can vary within species and may be influenced by factors such as sexual dimorphism, which is often poorly quantified in non‐commercial or understudied ...

PISCO: Intertidal: Barnacle Fecundity Monitoring: OSU: 2007

open access: yes, 2011
This metadata record documents the barnacle fecundity data for the PISCO intertidal. The reproductive state of two barnacle species is monitored monthly at 6 intertidal PISCO sites.

Effect of visual and electrosensory deterrents on captive elasmobranchs

open access: yesJournal of Fish Biology, EarlyView.
Abstract Commercial gillnet fisheries interact with a wide range of elasmobranch species, many of which are incidentally captured as bycatch. Deterrent technologies have emerged as a potential approach for reducing interactions with threatened elasmobranchs.

Site fidelity and homing behaviour in intertidal fishes

open access: yesMarine Biology, 2013
The theory of ecological cognition poses that the brains and behaviour of animals are shaped by the environmental challenges they face in their everyday lives. Site fidelity and homing ability was tested for five species of intertidal rock pool fish by tagging and displacing them to new rock pools at various distances from their ‘home’ rock pools ...
