“…The egg size was smaller when compared with other larger decapod species, like Macrobrachium nipponese (Zhao et al, 2007). The fecundity rate of C. pseudogracilirostris was 100 ± 30 to 300 ± 50 which was similar with Periclimenes paivai 229.08 ± 120.04 (De Moraes et al, 2017) and very low when compared with other species like Macrobrachium vollenhovenii (Sintondji et al, 2019), where a single female can produce about 83,000 eggs.…”

This paper reports on the real‐time imaging and developmental biochemistry of the freshwater caridean shrimp, Caridina pseudogracilirostris. The complete time‐lapse development of a single embryo was recorded in an artificial mold, developed in our lab, and imaged under a stereomicroscope. It took 8 days to complete the 5 stages of embryonic development (1 cleavage stage, 2 gastrulation stage, 3 nauplius stage, 4 prehatching embryo, and 5 zoea stages). As the decapod eggs are enriched with dense yolk, biochemical determination of the major components was made to evaluate the yolk utilization during embryogenesis. The concentration of protein, lipid, and carbohydrate declined drastically from Stage I (cleavage) to Stage IV (Zoea), reflecting sustained yolk utilization during embryogenesis. The increase in the size of the embryo correlates with changes in water content. Lipids, being the principal organic substrate, changes in the fatty acid (FA) composition of embryos during development were determined by GC. The FA composition was observed within the range of 25%–60.87% for saturated, 22.57%–56.45% for monounsaturated, and 5.64%–18.51% for total polyunsaturated FAs. The essential polyunsaturated fatty acid were higher in Stages I, IV, and V, suggesting a major role in embryogenesis. The cellular proliferation and organogenesis as visualized in the real‐time imaging correlate well with the biochemical variations observed in C. pseudogracilirostris.

“…The results of this study allowed us to evaluate the period of shrimp settlement in the lake. Indeed, from December to June, the salinity of lake Nokoué increases, which indicates a favourable environment for Penaeus juveniles: Penaeus monodon, Penaeus Kerathurus, Penaeus notialis; but also an essential environment for the survival and development of larvae of the Macrobrachium species: M. dux, M. felicinum, M. vollenhoveni, M. macrobrachion, M. raridens, M. sp; and of the genus Atya: Atya gabonensis; Atya africana (Table 1) [26,57,59]. These results are con rmed by the results of four months of sampling of Penaeidae conducted by [27] on lake Nokoué.…”

BackgroundThe export of shrimp to the European Union was one of the mainstays of the Beninese economy. It is an income-generating activity for the populations living along lake Nokoué. The lack of a fisheries management strategy has caused a drastic decline in shrimp production in lake Nokoué since 2003. To remedy this problem, it is necessary to hypothesize on their spatio-temporal dynamics in the lake Nokoué-Cotonou channel complex. This is investigated by combining a literature review on their life cycles and habitat suitability with spatio-temporal evolution of salinity obtained from in-situ observations.ResultsThe literature review recognizes the presence in southern Benin of species of the genus Macrobrachium, Atya and Desmocaris (seven, two and one respectively) and five species of marine shrimps belonging to three genera: the genus Penaeus, the genus Holthuispenaeopsis and the genus Parapenaeus. From information on the ecology and physical environment it is shown that adults of the species of the genus Macrobrachium and genus Atya have a favorable environment in lake Nokoué from August to November, their larvae must remain in the lake from December to June to ensure their survival. The species of the genus Desmocaris, which carry out their entire life cycle in fresh water, can stay in lake Nokoué from August to November. The species of the genus Penaeus can find a favorable environment in lake Nokoué from December to June but their larvae can only survive in the sea. Finally, the species of the genus Holthuispenaeopsis and Parapenaeus spend their entire life cycle at sea.ConclusionsThis work allows understanding contrasted life cycles of shrimp’s genera Macrobrachium and Atya compared to Penaeus in a complex ecosystem characterized by strong saline variation. This research allows to predict the presence or absence of shrimp’s genera Macrobrachium, Atya, Desmocaris and Penaeus in a lake system, on the basis of salinity distribution, for a sustainable management of their exploitation.

“…Differences in morphometric characteristics are caused by many variables, including temperature, dissolved oxygen, ammonia, salinity, photoperiod, competition, quantity and quality of food available, age, mortality rate, and interactions between these variables to influence fish growth, which can cause differences in morphometric characteristics (Bertin et al 2020;Sintondji et al 2020;Yulianto et al 2020). Each species will have a different absolute size from each other.…”

Abstract. Lamadi A, Paricahya AF, Iranawati F, Widodo MS, Wiadnya DGR. 2023. Genetic and morphological analysis of complex Giuris group species from Limboto Lake, Gorontalo Province, Indonesia. Biodiversitas 24: 5223-5233. Wallacea, especially Sulawesi, has a high endemism level with genuine biodiversity for mammals, reptiles, freshwater, and brackish fishes. Fish biodiversity in Limboto Lake, a great natural lake of Gorontalo Province, Indonesia, still needs to be scientifically explored, in contrast with its utilization for human activities that have anthropogenic effects on their ecosystem. Eleotridae is a taxonomical complex to their identification and distributed well in Sulawesi, including Limboto Lake with genus Giuris, known locally as hulu'u fish. Ambiguous identification in Giuris margaritaceus morphologically causing misidentification in molecular analysis, including using Cytochrome Oxidase subunit I (COI) region's information. Giuris specimens from Limboto Lake were collected from June 2022 until May 2023. From 662 individuals, length and weight relationship analysis results showed the population is mildly positive allometric (W= 0.11TL3.08). Meristic measurement result (D1 VI; D2 I.8-9; A I.9; P 14-16; V I.5; C 13-14) directing to G. margaritaceus with several small differences. COI analysis using six random specimens of the Limboto Lake population, comparing with four population from NCBI and BOLD System identified as G. margaritaceus or its synonym Ophieleotris aporos, indicating all populations is separated species from one another with P-distances more than 2% and made separated groups in phylogenetic tree and haplotype network. Misidentification issues in the Giuris margaritaceus taxonomical name for all five populations indicate they're potentially separated into five different species, with or without including Giuris margaritaceus, and potentially from currently described species or being new species in the future. Limboto Lake population made three haplotypes with high haplotype diversity (0.733) and low nucleotide diversity (0.001), indicating this population is facing high stressors and starting to grow. Understanding Giuris ambiguities could help governments, researchers, conservationists, and other stakeholders to mapping the ecological priorities.
