“…In general, the total fatty acid profiles of males' invasive blue crab; found in our study, were similar to females. This finding is in harmony with other studies [49,50]. The major differences were detected in the SFA to be significantly higher in male tissue (p < 0.05).…”

“…The C20:0 and C22:0 long chain n-3 fatty acids, such as, EPA and DHA, which are vital for human well-being, were found to be predominant in the edible part of the crab species. The long chain n-3 PUFA, especially EPA and DHA were found to be essential in the management of several health issues like cardiovascular illnesses, hypertension, diabetes, joint inflammation, and other inflammatory diseases [50]. Essential fatty acids sum (EFA) included also the long chain n-6 PUFA, especially, linolenic (C18:2n-6) and arachidonic (C20:4n-6) acids.…”

The invasive Portunus segnis, an atlantic species, was recently recorded in Tunisian waters. Since its record in the Gulf of Gabes, no studies have been carried out about the biochemical analysis of this alien species. In this context, our study aims to evaluate the fatty acid profile, lipid classes (neutral and polar), and nutritional value of breast of this invasive species. Specimens sampled from the gulf of Gabes were found to be rich in protein and oil, with significant differences between sexes. The level of saturated, monounsaturated, and polyunsaturated fatty acids in neutral and polar showed a significant difference between sexes. Saturated fatty acids were significantly higher in male P. segnis compared to the female. Docosahexaenoic (DHA), eicosapentaenoic (EPA), and arachidonic (ARA) were the most predominate polyunsaturated fatty acids (PUFA) in all oil classes. Oleic (C18:1) and Palmitoleic (C16:1) were the most abundant in monounsaturated. Palmitic (C16:0) and Stearic (C18:0) were the major saturated fatty acids. Consequently, the breast of P. segnis was a valuable source of high oil quality: It is rich in essential fatty acids and has an important n‐3/n‐6 ratio in both male and female blue crab. Therefore, the atherogenicity and the thrombogenicity were also evaluated, showing that P. segnis is a shellfish of greater value for human consumption in Tunisia.

“…The results of this study show that the major prey organisms of Portunus segnis and P. sanguinolentus are slow moving benthic invertebratess such as bivalves, crustaceans and gastropods. These findings of the present study support to those of [3], [7], [13], [14], [16] and [24].…”

“…Similar observation had been reported by [3] for P. segnis from Tanzania. However, [25] and [16], from Bahrain and Iran respectively, found fish as one of the major food items for P. segnis [14] and [7], who studied dietary composition and biology, respectively, of P. segnis from Persian Gulf, found crustaceans, molluscs and fishes as major food items. It is however debatable whether the fish consumed by Portunus spp.…”

The frequency of occurrence and points methods were used for the stomach contents analysis. Out of 558 P. segnis and 426 P. sanguinolentus, 254 (45.52%) and 227 (53.3%) crabs had empty stomach, respectively. Mollusca and Crustacea dominated the diet of both the species. According to points method Mollusca and Crustacea scored 67.28% and 53.8% points in P. segnis and P. sanguinolentus, respectively. When analyzed by frequency of occurrence method Mollusca and Crustacea occurred in 88.37% and 71.4% stomachs in P. segnis and P. sanguinolentus, respectively. Majority of the Mollusca eaten by P. segnis and P. sanguinolentus were small soft-shelled bivalves while Crustacea included mostly small crabs. Small fish, shrimps, polychaete worms, sponges, starfishes, brittle stars, bryozoans, and plant (algae) materials were also present in some stomachs in small quantity. Results of the present study suggest that the two crab species are opportunistic predator competing for food in the natural environment.

Feeding ecology of invasive lionfish (Pterois volitans and Pterois miles) in the temperate and tropical western Atlantic

et al. 2018

Numerous location-based diet studies have been published describing different aspects of invasive lionfish (Pterois volitans and Pterois miles) feeding ecology, but there has been no synthesis of their diet composition and feeding patterns across regional gradients. 8125 lionfish stomachs collected from 10 locations were analyzed to provide a generalized description of their feeding ecology at a regional scale and to compare their diet among locations. Our regional data indicate lionfish in the western Atlantic are opportunistic generalist carnivores that consume at least 167 vertebrate and invertebrate prey species across multiple trophic guilds, and carnivorous fish and shrimp prey that are not managed fishery species and not considered at risk of extinction by the International Union for Conservation of Nature disproportionately dominate their diet. Correlations between lionfish size and their diet composition indicate lionfish in the western Atlantic
