Reproductive cycle and sexual maturity size of landed Selene peruviana (Perciformes: Carangidae) on the coasts of the Ecuadorian Pacific

Ciencias Marinas, 2023
The Peruvian moonfish (Selene peruviana) is an important fisheries resource that is landed in the main fishing harbors of Ecuador. At the local level, little information is available regarding the biology of this species, which hinders the development ...

Increased energetic cost of movement reduces reproductive output in zebrafish at different temperatures and water flow rates

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Locomotion consumes a large proportion of individual energy budgets and may impose energetic constraints on other fitness‐related traits particularly under variable environmental conditions.

Length‐Based Spawning Potential Ratio Assessment of Key Species From a Remote Recreational Fishery at Diego Garcia, Indian Ocean

Fisheries Management and Ecology, EarlyView.
ABSTRACT Recreational fisheries in remote regions often operate under limited regulation and data availability, presenting challenges for sustainable management. Diego Garcia, located within the Chagos Marine Protected Area, hosts a unique recreational reef fishery embedded within a highly protected environment. We assessed the stock status of five key

Body size of male Atlantic salmon (Salmo salar L.) at introduction of a 5‐week LD12:12 winter signal influences their decision to mature early or smoltify

Journal of Fish Biology, EarlyView.
Abstract Sexual maturation of male Atlantic salmon post‐smolts (‘jacking’) is undesired in aquaculture and seems to occur due to the intensification in modern facilities. Maturation depends on internal and external factors (temperature, photoperiod, feed availability, energy levels, body size, genetic background) that act on the brain‐pituitary‐gonad ...

Length-Weight Relationship, Condition Factor and Fecundity of African Snakehead Parachanna obscura from the Anambra River, South East Nigeria

Croatian Journal of Fisheries, 2019
The length-weight relationship, condition factor, fecundity, gonadosomatic and hepatosomatic indices of Parachanna obscura from the Anambra River were determined between December 2015 and June 2016. Eighty-three live samples of P.

The physiological response of juvenile diploid and triploid Arctic charr Salvelinus alpinus to exhaustive exercise

Journal of Fish Biology, EarlyView.
Abstract Triploidy is an effective tool for producing sterile fishes but often results in impaired performance in commercial aquaculture. In light of this, our study compared the physiological response to exhaustive exercise in juvenile diploid and triploid Arctic charr Salvelinus alpinus, a polar species with great potential for aquaculture.

Effects of Body Size and Environmental Region on the Nutritional Value of Small Pelagic Species in the California Current

Fisheries Oceanography, Volume 35, Issue 5, Page 722-736, September 2026.
ABSTRACT We evaluated the effects of regional environment and body size on the nutritional traits of five small pelagic species differing in habitat use, feeding behavior, and importance as prey for top predators in the California Current Large Marine Ecosystem (CCLME).

Using the gonadosomatic index to estimate the maturity ogive: application to Chilean hake (Merluccius gayi gayi) [PDF]

ICES Journal of Marine Science, 2014
Abstract The proportion of mature fish at age or length is one of the most important population attributes in assessing reproductive potential. This proportion is usually named the maturity ogive. The most crucial step in estimating this proportion deals with maturity staging assessed by macroscopic or histology analysis.
