Hogfish, Lachnolaimus maximus (Walbaum), have multiple traits that confound measuring reproductive potential: they are protogynous, relatively long-lived harem-forming fish that spawn daily for months. Additionally, recent evidence demonstrates that size, age and timing of sex change vary on a spatial scale within the study area (West Florida shelf, USA). This study investigates the effect of this spatial variation on hogfish reproductive potential by evaluating spawning seasonality, spawning… 
Reproductive benefits of no-take marine reserves vary with region for an exploited coral reef fish
TLDR
The results show that while NTMRs can potentially provide a substantial recruitment subsidy (central GBR reefs), they may provide a far smaller subsidy (southern GBR), or serve as recruitment sinks (northern GBR) for the same species in nearby locations where demographic rates differ.
Reproductive biology and management of two commercially important groupers in the SW Atlantic
TLDR
Results demonstrate a positive relationship between GSI peaks, lower temperatures and stronger winds and may help decision-making regarding fisheries management and conservation for E. morio and M. bonaci in the Abrolhos Bank.
Oocyte distribution within and between ovary lobes is largely homogeneous in Lachnolaimus maximus (Perciformes: Labridae).
TLDR
A preliminary study was done of gonad oocyte distribution mode in a hogfish Lachnolaimus maximus population in the southern Gulf of Mexico, where heterogeneity was present in tertiary vitellogenesis oocytes in the right lobe of females in the spawning capable reproductive phase.
Queen triggerfish Balistes vetula: Validation of otolith-based age, growth, and longevity estimates via application of bomb radiocarbon
TLDR
This work indicates that previously reported maximum ages for Balistes species based on spine-derived age estimates may underestimate longevity of these species since queen triggerfish otolith-based ageing extended maximum known age for the species by nearly three-fold.
Length-weight relationships of four finfish commercial species from the southern Gulf of Mexico
TLDR
The relationship between total length and total weight (LWR) of four commercial species of finfish captured in the southern Gulf of Mexico was estimated and this type of information is an important input for the stock assessment of these species that support important fisheries in the zone and are under high fishing pressure levels.
Fish Spawning Aggregations in the Southeast Florida Coral Reef Ecosystem Conservation Area: A Case Study Synthesis of User Reports, Literature, and Field Validation Efforts
The formation of fish spawning aggregations (FSAs) is an essential part of the life history of many economically important fish species; however, their status are often poorly described in the
Evolutionary and demographic impacts of sex change rules and size-selective exploitation on sequential hermaphrodites
TLDR
Results from these models highlight the need for a better understanding of sex change rules for exploited hermaphrodites and how life-history-traits and population reference points change due in part to evolution.

Regional Variations of Hogfish (Lachnolaimus maximus) Life History: Consequences for Spawning Biomass and Egg Production Models
TLDR
The results here demonstrate how the SSB/R model can overstate the resiliency of fish stocks to recruitment overfishing and the potential benefits to yield and recruitment that could result from an increase in the minimum size limit of hogfish.
Spatial variation in the effects of size and age on reproductive dynamics of common coral trout Plectropomus leopardus.
TLDR
Significant regional variation in reproductive traits suggests that a regional approach to management of P. leopardus is appropriate and highlights the need for considering spatial variation in reproduction where reserves are used as fishery or conservation management tools.
Fishery-induced demographic changes in the timing of spawning: consequences for reproductive success*
TLDR
Modelling approaches are suggested that can better quantify the likely impact of changing spawning times on year-class strength and lifetime reproductive potential and the need to avoid fishing severely age truncated fish stocks is strengthened.
Sexual development and reproductive seasonality of hogfish (Labridae: Lachnolaimus maximus), an hermaphroditic reef fish
The seasonality, size, age, colour phases and sexual dimorphism of 13 reproductive classes of hogfish Lachnolaimus maximus are described. Analysis of histological sections of gonads (n = 1662)
Impacts of demographic variation in spawning characteristics on reference points for fishery management
TLDR
Traditional approaches to F-based reference points using SSB systematically overestimate the resiliency of stocks to fishing and if age-at-spawning is at least partially heritable, then intense fishing on younger ages may exert high levels of selection for early maturity with negative impacts on net reproductive effort and trait diversity.
An indeterminate model to estimate egg production of the highly iteroparous and fecund fish, dolphinfish (Coryphaena hippurus)
TLDR
This study, which examined gonad histology, substantially increases estimates of dolphinfish spawning fraction and annual egg production and concludes that spawning early and often should make C. hippurus resilient to overfishing, but other data gapsconfound the ability to evaluate the effectiveness of size regulations in the fishery.
Localized Spatial and Temporal Variation in Reproductive Effort of Florida Bass
TLDR
Evidence is found for multiple spawning events per adult and for skipped spawning in Florida Bass populations across four lakes in north-central Florida, where factors such as skipped spawning could influence recruitment processes.
Maternal effects in rockfishes Sebastes spp.: A comparison among species
TLDR
It is confirmed that older and larger females in rockfish populations may contribute disproportionately to larval recruit- ment by producing higher quality larvae and more larvae per unit biomass, and releasing them at a different time than younger and smaller females.
