Abstract Populations of Platorchestia platensis were collected throughout the annual season at Indian Point (N.B., Canada), then acclimated (wrack or driftwood) and oxygen uptake measurements were made on individuals at standard temperature (approx. 19°C) and lighting conditions (12 12-hour light dark). P. platensis reduces resting rate (= standard metabolic rate, SMR) and growth and reproduction cease (diapause) during the colder months. SMR and growth begin increasing when the warm season starts towards the end of March at Indian Point. Wrack-acclimated P. platensis SMR peaks near the summer solstice in June and a month later for driftwood-acclimated populations. The SMR of wrack-acclimated P. platensis at 45°N begins dropping, following the June peak, towards a period of overwintering dormancy (= diapause) to be reached near the vernal equinox in September. Wrack-acclimated populations of P. platensis in winter maintain their inverse metabolic relationship with size. During winter in driftwood-acclimated populations, the relationship with weight is lost.

Abstract The pink spiny lobster, Palinurus mauritanicus Gruvel, 1911 is a target species of commercial fisheries along the Algerian west coast. To better understand the natural diet of a population of P. mauritanicus , a study was conducted between June 2021 and May 2022, which aimed to compare the consumed food items based on sex, seasonality, and body size. This approach involved analysing stomach contents and determining ingested prey, with seasonal sampling conducted at three main fishing ports (Béni Saf, Bouzedjar and Oran). The results showed that fish (in general “Pisces”, but only Osteichthyes retrieved) (46.42%), Crustacea (34.28%), Annelida Polychaeta (23.33%), and Mollusca (18.57%) were the major components of the lobster’s diet. Echinodermata (8.57%), Porifera (2.38%) and Bryozoa (0.95%) were classified as minor groups. We also showed that sex and season affected the prey items consumed by the lobster. Based on the vacuity index, the pink spiny lobster was found to be feeding intensively in spring and decreasingly so in summer, autumn and winter. These results indicate that the pink spiny lobster is to be characterized as an omnivorous generalist and opportunist.

Abstract Astaxanthin (Axn) is the primary pigment molecule in crustaceans associated with quality, health and growth traits, leading to increased marketing value. Axn can be contained within the protein complex crustacyanin (CRCN) to produce an array of different shell colours, or esterified with fatty acids (FA) for storage but also contributing additional red colouration. l -Carnitine (LC) has a major role in FA oxidation and mitochondrial function optimization, which could influence the proportion of Axn complexed with FA or CRCN. Peroxisome proliferator activated receptors (PPARs) have important roles in FA and Axn uptake, and stored lipid oxidation affecting Axn homeostasis and storage in lipid bodies. Whether Axn could increase PPAR signalling and carnitine palmitoyl transferase activity, leading to induction of lipid metabolism, is not known in crustaceans. Several FA have been shown to preferentially form FA Axn-esters, including saturated fatty acids (SFA) such as C16:0 and C18:0, mono-unsaturated fatty acids (MUFA) such as C16:1 and C18:1, and poly-unsaturated fatty acids (PUFA) such as C20:4, C20:5, and C20:6. We hypothesize that manipulating the dietary ratios and inclusion of LC, Axn, and specific FA may be able to further improve pigment utilization, lipid metabolism, health, and growth in crustaceans.

Abstract The northern Chilean coast is characterized by its high productivity and diversity due to the presence of the cold, nutrient-rich water of the Humboldt Current. In this scenario, the rocky shore provides many microhabitats for invertebrates such as crustaceans. The aim of the present study was to analyse potential species interactions using probabilistic models and contingency tables. In this particular case we analysed the potential interactions between two sympatric intertidal decapods, Cyclograpsus cinereus and Petrolisthes granulosus , on the rocky shores of Cifuncho Bay, an isolated bay in the north of Chile. The results revealed that both species had a uniform pattern, that was adjusted to a binomial distribution for C. cinereus , and a Poisson distribution for P. granulosus . These results are probably due to territorial behaviour, and this was corroborated by the results of the contingency table, which denoted the independence of both species. These results would not coincide with classical observations of intertidal decapods on rocky shores of continental Chile, as those denoted a gregarious pattern. However, on the other hand, the present results do not explain any details about potential interactions between the two species here analysed.

Abstract Two cylindrical crabs, Ixa cylindrus (Fabricius, 1777) and Ixa edwardsii Lucas, 1858 are herein recorded for the first time from the coastal waters of the eastern Arabian Sea. Both species were collected from the bycatch landing of the commercial demersal trawlers operated along the Gujarat coastal region, northwest coast of India, between 20 and 80 m depth. Both species have been recorded from the Bay of Bengal on the east coast of India, but there is no detailed information available on their taxonomic identification and global distributional records.
