“…While most previous crevalle jack diet studies reported prey in the order Clupeiformes as the most dominant prey (Correia et al, 2017;Fagade & Olaniyan, 1973;Kwei, 1978;Saloman & Naughton, 1984), we found that prey in the order Sciaeniformes (48.8% PSIRI), particularly Atlantic croaker (42.0% PSIRI), was far more important in diets of crevalle jack in Mississippi and Alabama. Since most of our diet data were obtained through fishery-dependent sampling, and fishes were the most common bait (86.9%), it is possible that our results could be biased by our sampling design.…”

“…Crevalle jack are generally diurnal predators, often creating surface‐water turbulence by feeding in schools on schooling prey near the surface (Correia et al, 2017; Kwei, 1978), though larger crevalle jack can be solitary (Carpenter, 2002). The diet of crevalle jack has been most thoroughly investigated in the eastern Atlantic off the coast of Africa.…”

“…The diet of crevalle jack has been most thoroughly investigated in the eastern Atlantic off the coast of Africa. There, adults feed predominantly on fishes in the family Clupeidae (Correia et al, 2017), juveniles on a mix of small fishes and shrimps (Fagade & Olaniyan, 1973; Kwei, 1978) and post‐larval individuals primarily on copepods (Kwei, 1978). However, some of these studies may have included longfin crevalle jack (Smith‐Vaniz & Carpenter, 2007).…”

The goals of this study were to generate baseline population dynamics parameters for Gulf of Mexico crevalle jack Caranx hippos and examine the foraging habits of Mississippi and Alabama crevalle jack. Specimens were collected from Mississippi, Alabama and Florida, and age was estimated from sagittal otoliths. Stomachs from some specimens were retained for dietary analyses. Age classes spanned 0-20 years.Overall growth was best represented by the logistic growth model, whereas sexspecific growth was best represented by a version of the von Bertalanffy growth function that allowed L ∞ to vary by sex while holding k and t 0 constant between sexes.Fishes were more important to crevalle jack diet than invertebrates, and diet varied among locations and years. These findings will address fundamental knowledge gaps to inform age-based stock assessments for crevalle jack and ecosystem approaches to fisheries management in the Gulf of Mexico.

“…was not yet observed as important in fish diet (e.g., Longhurst, 1957;Correia et al, 2017;Clements et al, 2022). Other fiddler crab species, however, have been identified as important prey for killifishes, puffers, and gobies in different regions (Krumme et al, 2007;Rozas & LaSalle, 1990;Zulkifli et al, 2012).…”

We present the first assessment of the diet of the blackchin guitarfish Glaucostegus cemiculus (Geoffroy Saint‐Hilaire, 1817) for West Africa, using DNA metabarcoding on stomach contents of individuals captured in the Bijagós archipelago, Guinea‐Bissau. The diet was dominated by crustaceans, particularly caramote prawn Penaeus kerathurus (frequency of occurrence FO=74%; numerical frequency NF=54%) and fiddler crab Afruca tangeri (FO=74%; NF=12%). Bony fishes occurred in 30% of the stomachs. We highlight the importance of conservation action for intertidal habitats and their associated benthic invertebrates for the survival of the critically endangered blackchin guitarfish.This article is protected by copyright.

“…Beyond its importance for fisheries, Sardinella maderensis has been shown to be the most frequent prey for several marine predators in the archipelago, such as seabirds and predatory fish (Correia et al, 2017(Correia et al, , 2018(Correia et al, , 2019. The fact that, in the Bijagós Archipelago, Sardinella maderensis is highly abundant and serves as the main link between plankton and marine predators, makes it a key species for the ecosystem.…”

In many marine ecosystems small pelagic fish exert a crucial role in controlling the dynamics of the community, mainly due to their high biomass at intermediate levels of the food web. These fish use coastal marine ecosystems as nursery areas, but also to forage and to avoid predation or competition. We studied spatial, seasonal, lunar and diel variations in a coastal fish community from a marine protected area of the Bijagós Archipelago, Guinea-Bissau. Fish were sampled with 46 beach seine net sessions in 2015 and 2016. A total of 35 fish species of 25 families were captured. Fish abundance varied between years and seasons, with a higher abundance in the dry season, but not by lunar tide. Nonetheless, the community composition was broadly similar over the seasons, among islands and between lunar tides. Clupeidae, Haemulidae and Gerreidae were the most abundant fish families. Sardinella maderensis highly dominated the captures throughout the year, with catches much higher than any other species. The differences in abundance between seasons and years may be related with movements to or from the shore due to feeding activity or to avoid predation, or else to differences in recruitment between years. There were no significant diel differences in species richness and diversity, although higher numbers of fish were captured during daytime. For most species the majority of individuals captured were immature, highlighting the importance of the archipelago as nursery area for several species. These small pelagics, and particularly Sardinella maderensis, represent the main prey for several marine predators. Thus, the conservation of such fish species may be key for the management of the Bijagós Archipelago.
