Special Issue Information

Dear Colleagues,

The Special Issue welcomes field or laboratory studies that test the life history effects of environmental variations, as well as reviews and theoretical papers on this topic.

Life histories regard how individuals grow and survive to maximize the number of highly viable offspring in competition with others. They quantify how individual traits are expressed in response to environmental change, and cover aspects such as habitat use, foraging, migration, dispersal, growth, age and size at maturity of sexes, length of life span, fecundity and reproduction, the timing of these traits, and how they change in response to environmental variation. These traits are all closely related to the fitness of individuals. Environmental changes may include variations in physical habitats, temperature, water flow and level, water quality, nutrient richness, vegetation, and conditions such as competition, predation, or anthropogeny influences like harvest regimes or any kind of pollution. Studies may include concepts such as polymorphism, ontogenetic niche shifts, stunting, partial migration, sex ratio variation, among others. Reaction norms of life history variables, in relation to environmental parameters, will help us predict how individuals and their offspring react to future environmental impacts, whether due to abiotic or a biotic influences. This knowledge is at the core of conservation ecology and important for the management of species.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Fishes is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Quantifying Age and Growth Rates of Gray Snapper (Lutjanus griseus) in Mosquito Lagoon, Florida

Gray snapper (Lutjanus griseus; Family: Lutjanidae) local habitat preferences have been assessed, but the biotic and abiotic factors influencing age and growth rates in Mosquito Lagoon, Florida, have not been quantified. To address this knowledge gap, the goal of this study was to estimate mean age and growth rate of gray snapper, and use generalized linear mixed models to investigate if prey and/or other environmental factors (e.g., abiotic/biotic conditions, time, location, or habitat restoration status) impact size at both the lagoon- and habitat-specific scales. Age data were extracted via otolith microstructural analyses, and incorporated with size into a lagoon-scale linear growth model. Based on microstructural analyses, mean age of gray snapper at the lagoon scale was 175 ± 66 days (range = 56–350 days). The results indicate the most common life stage of gray snapper in Mosquito Lagoon is juveniles, with living shoreline habitats having a greater proportion of relatively young juveniles (111 ± 36 days) and oyster reef habitats having a greater proportion of relatively older juveniles (198 ± 58 days). The estimated growth rate was 0.43 mm/day. Body mass and body length were correlated positively with habitat quality and lagged salinity levels. Hence future studies should strive to characterize benthic habitat characteristics, and investigate biotic and abiotic factors that potentially influence gray snapper growth. Collectively, this study increases our understanding of environmental drivers affecting juvenile gray snapper development and shows that the restoration of benthic habitats can produce conditions conducive to gray snapper growth. The age-, size-, and habitat-specific growth rates of juveniles from this study can be incorporated into stock assessments, and thereby be used to refine and develop more effective ecosystem-based management strategies for gray snapper fisheries.

This study focuses on the behavior of the Round Goby in relation to various types of hard substrates, which may be crucial in the context of the emergence of hydrotechnical structures in their habitat. The aim of this study was to determine the behavior and habitat preferences of the Round Goby in relation to specific types of hard substrates. Three types of substrates were used in the experiments: bare, colonized by benthic organisms, and rocky. Laboratory observations were conducted and divided into three variants, each with two cycles—daytime and nighttime. Each variant involved different combinations of two substrates. It was found that during the day, fish spent more time on vegetated substrates than on bare or rocky ones. At night, the opposite trend was observed. The lowest activity was recorded when the fish had a choice between bare and rocky substrates. The largest fish in the experiments changed their habitat most frequently, indicating that body size influences the activity level. However, no significant differences were found in either the time spent on specific substrates or the number of substrate changes. In addition, it was observed that the total length of Round Gobies did not affect their activity level. Full article
