“…Several stomachs of both species caught by hook and line, longline and spear fishing were empty. Despite the fact that some fish species regurgitated their prey(s) after capture, as already stated for some large-fish species (Randall, 1967), including groupers (Randall, Brock, 1960;Nakai et al, 2001;Dierking, Meyer, 2009), we suspect that epinephelids regularly experience long periods of empty stomachs (e.g. Condini et al, 2011;López, Orvay, 2005;Reñones et al, 2002), as a combined result of resource availability, digestion rates and energy balance (Arrington et al, 2002).…”

Feeding ecology of two sympatric species of large-sized groupers (Perciformes: Epinephelidae) on Southwestern Atlantic coralline reefs

Red and black groupers are large-bodied opportunistic ambush predators commonly found in Southwestern Atlantic tropical reefs. We investigated the diet of both species in order to detail ontogenetic, spatial and temporal trends, and to assess the extent of overlap in resource use between these two sympatric predators on the Abrolhos Bank, Brazil. Decapods and fishes were the main food items of Epinephelus morio while fishes were the main prey of Mycteroperca bonaci. Both diets were significantly influenced by body size and habitat, but only smaller individuals of E. morio feed almost exclusively on crustaceans. While the two groupers rely on many of the same prey types, coexistence may be facilitated by E. morio feeding more heavily on crustaceans, particularly the blackpoint sculling crab Cronius ruber, while black grouper take comparatively few crustaceans but lots of fish prey. Predators like red and black groupers could trigger indirect effects in the community and influence a large range of ecological processes, such as linkages between top and intermediate predators, and intermediate predators and their resources.

“…Feeding periodicity was determined by analyzing the feeding intensity and the empty stomach ratio. The stomach fullness index (SFI) 11 was adopted to measure the degree of feeding intensity, and it was calculated as follows: SFI = [weight of the stomach contents/(body weight − weight of the stomach contents)] × 100. The empty stomach ratio (ESR) was calculated as the percentage of the number of specimens with an empty stomach, of the total number of examined specimens.…”

Food and feeding habits of ribbonfish Trichiurus lepturus in coastal waters of south-western Taiwan

et al. 2006

View full text Add to dashboard Cite

The catch of ribbonfish Trichiurus lepturus in the coastal waters of south-western Taiwan has significantly declined in recent years. To examine the effects of exploitation on the feeding habits of ribbonfish, 1570 specimens were collected on a monthly basis during March 2002-March 2003 from the landings by trawlers operating in the coastal waters of south-western Taiwan. The size of the ribbonfish ranged from 83-298 mm preanal length (PL), with a peak at 201-250 mm PL. Although they fed on shrimps and squid, fishes including Benthosema pterotum, Bregmaceros lanceolatus and Encrasicholina heteroloba were their main food items. In particular, B. pterotum was the most important food all year except during summer. No evidence of cannibalism was found in this study. No differences between day and night were found in the feeding activity of T. lepturus. However, B. pterotum and Acetes intermedius were the most important prey in the daytime, whereas B. lanceolatus, B. pterotum and E. heteroloba were at night. Feeding activity and the number of food items increased with increasing size of ribbonfish. Their feeding intensity in February to June, the main spawning season, was significantly greater than in other months. Changes in the food and feeding habits of this species before and after the recent period of heavy exploitation are discussed in detail in this study.

“…Food habits of these, or similar, species have been generally reported before, both in the NES and other ecosystems (Richards et al 1979, Atkinson & Percy 1992, Hood et al 1994, Lindquist et al 1994, Manderson et al 1999, Steimle et al 1999, Garrison 2000, Nakai et al 2001, Perez-Espana et al 2005, Jaworski & Ragnarsson 2006, Drohan et al 2007). These species are generalist carnivores consuming mostly crabs, amphipods, polychaetes, mollusks, and small fish (Hood et al 1994, Lindquist et al 1994, Steimle et al 1999, Nakai et al 2001, Drohan et al 2007). Studies of related species in other systems suggest that temporal, spatial, or ontogenetic variation exists in the diet (Kingsford 1992, Greenstreet et al 1998, St. John 1999, Steimle et al 2000, St. John et al 2001.…”

Evidence of species interactions are generally well understood over broad temporal and spatial scales, particularly for commercially valuable species. Yet species that are not as commercially valuable may nonetheless be ecologically important in stabilizing trophic interactions in large marine ecosystems. We examined the diets for 4 of these demersal fish species: black sea bass Centropristis striata, scup Stenotomus chrysops, Northern searobin Prionotus carolinus, and striped searobin P. evolans. We examined food habits data across size class, season, 5 yr time block, and geographic region to evaluate the major determinants of diet composition. We used multivariate statistics, specifically canonical correspondence analysis, as the primary method to explore diet determinants. Our results showed that the scup and 2 searobin species are primarily benthivorous, whereas black sea bass notably shifts towards piscivory with ontogeny. Our results also showed that the diet of these predators was mainly influenced by size class, region, and (to a lesser extent) season, whereas 5 yr time block did not notably influence diet composition, a surprising observation given the welldocumented changes to benthic habitat in this ecosystem. These results suggest that these species feed opportunistically in proportion to the relative abundance of available prey given the constraints of their morphology, which implies that despite notable impacts to benthic habitat, the prey field for these understudied species has been consistent (within seasonal variation) over the past 3 decades. Stable feeding dynamics such as these may act to enhance resilience in large marine ecosystems.KEY WORDS: Black sea bass · Scup · Northern searobin · Striped searobin · Benthic · Ontogenetic shifts · Northwest Atlantic · Canonical correspondence analysis 406: 239-250, 2010 thought to enhance stability of the food web, which can then enhance the stability and resilience of the entire system (Holling 1973). Predator-prey relationships may differ at different spatial and temporal scales and with varying degrees of disturbance. The scale at which these stabilizing mechanisms take place and the severity of disturbance may determine the extent to which the system can be managed, or at least its resilience for management assumptions, functionally speaking (Auster & Link 2009). Therefore, examining a system and the interactions with that system at the same scale at which it is managed is critical (Sherman 1991(Sherman , 1994(Sherman , 2006.
