“…Freshwater shrimp in the family Atyidae occur worldwide, except Antarctica; they are the most diversified decapod crustaceans (Decapoda: Caridea) and are found in various freshwater bodies from fast-moving mountain streams to sluggish, oligohaline waters (De Grave et al, 2008;De Grave & Fransen, 2011). Atyid shrimp play important roles in stream food webs as primary consumers (Pringle et al, 1993;Crowl et al, 2001;March & Pringle, 2003;Oeding et al, 2020). Some atyid species are fished for local food (Holthuis, 1980;De Grave et al, 2008), and they are also harvested wild and cultured for the aquarium trade (Heerbrandt & Lin, 2006;De Grave et al, 2008.…”

“…To overcome this limitation, in the last decade, special Bayesian-based approaches have been developed for cases with many (>3) food sources [ 19 ]. This type of approach revealed changes in the diet, which included four food sources, of the freshwater shrimp Paratya australiensis inhabiting ecosystems differing in the availabilities of autochthonous and allochthonous organic matter [ 20 ]. The Bayesian models use probability distributions of the compounds (isotopes) to estimate the contributions of multiple food sources to the diets of consumers.…”

Assessing the Reliability of Quantitative Fatty Acid Signature Analysis and Compound-Specific Isotope Analysis-Based Mixing Models for Trophic Studies

The study of the trophic relationships of aquatic animals requires correct estimates of their diets. We compared the quantitative fatty acid signature analysis (QFASA) and the isotope-mixing model IsoError, based on the compound-specific isotope analysis of fatty acids (CSIA-FA), which are potentially effective models for quantitative diet estimations. In a 21-day experiment, Daphnia was fed a mixture of two food items, Chlorella and Cryptomonas, which were supplied in nearly equal proportions. The percentages and isotope values of the FAs of the algal species and Daphnia were measured. The IsoError based on CSIA-FA gave an estimation of algae consumption using only one FA, 18:3n-3. According to this model, the proportion of consumption of Chlorella decreased while the proportion of consumption of Cryptomonas increased during the experiment. The QFASA model was used for two FA subsets—the extended-dietary subset, which included sixteen FAs, and the dietary one, which included nine FAs. According to both subsets, the portion of consumed Chlorella decreased from Day 5 to 10 and then increased at Day 21. The comparison of the two model approaches showed that the QFASA model is a more reliable method to determine the contribution of different food sources to the diet of zooplankton than the CSIA-based mixing model.

Larval performance of three amphidromous shrimp species in the genus Caridina (Decapoda: Caridea: Atyidae) under different temperature and salinity conditions

We examined the effects of temperature and salinity on larval survival, duration, and growth of three amphidromous atyid shrimps, Caridina leucosticta, C. multidentata, and C. typus to infer larval dispersal strategy in the sea. Larvae were reared under 25 combinations of five different temperature (20, 23, 26, 29, and 32 °C) and salinity (4.25, 8.5, 17, 25.5, and 34 ppt) levels. Interspecific variability was detected in larval performance: C. leucosticta larvae were able to survive to moult into the juvenile stage at the lower salinity condition (8.5 ppt), C. multidentata larvae exhibited an ability to adapt to the wide range of salinity condition (17-34 ppt), and C. typus larvae adapted to the higher salinity condition (34 ppt) better than C. leucosticta larvae. Larval duration was less variable between species. Thus, salinity adaptation of larvae may play an important role in mediating the larval dispersal of the three Caridina species in the sea. Larval dispersal range may be most limited near the river mouth for C. leucosticta, and be moderate for C. typus, and C. multidentata larvae may be able to disperse broadly under the high salinity condition of the open sea.
