Ovarian development, spawning season, size at maturity and fecundity of Acentrogobius viridipunctatus (Valenciennes, 1837) in the Vietnamese Mekong Delta [PDF]

open access: yesPeerJ, 2022
This present study provides an overview of the reproductive traits, including ovarian development, spawning season, size at maturity (Lm), and fecundity of Acentrogobius viridipunctatus – a high economic value fish in the Vietnamese Mekong Delta (VMD). A

Influence of Size and Maturity on Injury in Young Elite Soccer Players [PDF]

open access: yesInternational Journal of Environmental Research and Public Health, 2021
The involvement of pre-adolescents in soccer is becoming more and more frequent, and this growing participation generates some concerns about the potential factors for sports injuries. The purpose of this study was to investigate sports injuries in younger (U9–U11) and older (U12–U13) children playing soccer at an elite level, analyzing potential ...

Spatial variability in size at maturity of golden king crab (Lithodes aequispinus) and implications for fisheries management [PDF]

open access: yesRoyal Society Open Science, 2018
Many crab fisheries around the world are managed by size, sex and season, where males are given at least one opportunity to reproduce before being harvested.

Spatial and temporal variations in female size at maturity of a Southern Rock Lobster (Jasus edwardsii) population: A likely response to climate change. [PDF]

open access: yesPLoS ONE, 2019
The size at which sexual maturity is reached is a key population parameter used to guide the setting of minimum legal size limits in fisheries. Understanding spatial and temporal variations in size at maturity is fundamental to management because the ...

Reproductive characteristics of doublespotted queenfish, Scomberoides lysan (Actinopterygii: Perciformes: Carangidae), from Sri Lankan waters: Implications for fisheries management [PDF]

open access: yesActa Ichthyologica et Piscatoria, 2013
Background. The doublespotted queenfish, Scomberoides lysan (Forsskål, 1775), is one of the most important and highly priced food fishes popular for dry fish production in Sri Lanka.

Reproduction of the invasive largemouth bass Micropterus salmoides (Lacepède, 1802) in a Neotropical reservoir with suggestions to management and control

open access: yesActa Limnologica Brasiliensia, 2023
Aim The largemouth bass Micropterus salmoides was introduced in more than 50 countries for the purpose of sport fishing. In Brazil, records date from 1922, and nowadays many populations are known to occur in the southern region.

Rapid reproductive analysis and length–weight relations for five species of coral-reef fishes (Actinopterygii) from Papua New Guinea: Nemipterus isacanthus, Parupeneus barberinus, Kyphosus cinerascens, Ctenochaetus striatus (Perciformes), and Balistapus undulatus (Tetraodontiformes) [PDF]

open access: yesActa Ichthyologica et Piscatoria, 2017
Background. We present length–weight relations (LWR) and describe the reproductive biology of five species of coral reef fishes from Papua New Guinea (PNG).  Each of these species are targeted by artisanal- and small-scale commercial ...

Survival probability and size of lineages in antibody affinity maturation [PDF]

open access: yesPhysical Review E, 2021
Affinity Maturation (AM) is the process through which the immune system is able to develop potent antibodies against new pathogens it encounters, and is at the base of the efficacy of vaccines. At its core AM is analogous to a Darwinian evolutionary process, where B-cells mutate and are selected on the base of their affinity for an Antigen (Ag), and Ag

Y‐chromosome haplotypes are associated with variation in size and age at maturity in male Chinook salmon

open access: yesEvolutionary Applications, 2020
Variation in size and age at maturity is an important component of life history that is influenced by both environmental and genetic factors. In salmonids, large size confers a direct reproductive advantage through increased fecundity and egg quality in ...

Disparate maturation adaptations to size-dependent mortality [PDF]

open access: yesProceedings of the Royal Society B: Biological Sciences, 2006
Body size is an important determinant of resource use, fecundity and mortality risk. Evolution of maturation size in response to size-dependent selection is thus a fundamental part of life-history theory. Increased mortality among small individuals has previously been predicted to cause larger maturation size, whereas increased mortality among large ...
