Existing studies on central Chilean inland waters only mention records of decapods, but there are no ecological studies about decapods and other crustacean groups. The aim of the present study was a first characterization of inland water crustaceans in Claro River, a Mediterranean-climate river from Chile. The results of redundance analysis (RDA) revealed that the crab Aegla affinis inhabits waters of high pH and low temperature values, whereas amphipods of the genus Hyalella inhabit habitats with high pH, high temperatures, and low values of dissolved oxygen. Finally, ostracods (family Cyprididae), isopods (Heterias sp.) and the southern river crayfish (Samastacus spinifrons) inhabit water systems with moderate values of pH, temperature, dissolved oxygen, and conductivity. This paper represents the first ecological report for crustaceans of central Chilean inland waters, and the results appear to be similar to comparable descriptions for northern Patagonian rivers.

The aim of this study is to determine the effect of different stocking volumes on the survival and growth of broodstocks of the blue crab, Callinectes sapidus. Based on a Pearson correlation test, 0.70 litre tanks with three groups at different stocking densities (15, 10 and 5 individuals per tank) have been used in this study. The results show that the mortality rate due to cannibalism was high in the first test group, while it was found to be lower in the third group. There were significant differences in survival rates in the three different groups used in this trial of broodstock cultivation (). The higher the stocking densities, the lower the survival rates, i.e., significantly increasing the broodstock density reduces the survival rate. Statistical differences have also been found in the development rates of broodstock crabs (), and it has been noted that there is slower development at higher stocking densities. If calculating the optimal stock density for mass production purposes is desired, less density thus appears to be more advantageous for both survival and growth rate.

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.
