“…Moreover, the Indian Ocean has a complex current system with the South Equatorial Current flowing westward across the Indian Ocean and splitting into the Southeast and Northeast Madagascar Current, which can facilitate long-distance larval dispersal as well as generate migration barriers ( Schott et al 2009 ; Otwoma and Kochzius 2016 ; Huyghe and Kochzius 2018 ). Considering the offshore planktonic larval phase (approximately 20 days) of P. monodon ( Motoh 1985 ), a stepping-stone model could explain larval dispersal throughout the entire Indian Ocean over several generations because the period of seasonal monsoons (northeast winds in December/January and southwest winds in July/August) corresponds with the peak P. monodon spawning seasons in the Indian Ocean ( Sk et al 2015 ; Kaka et al 2019 ). Although we do not know the exact divergence time between the ancestral (WIO populations) and the Indo-Polynesian lineage (Sri Lanka, Southeast Asia, Australia, and Fiji), it could have occurred during the late Pleistocene given the lineage divergence timing of other species in this region ( Vogler et al 2012 ; Hui et al 2016 ; Farhadi et al 2017 ; Huyghe and Kochzius 2017 ).…”

The giant black tiger shrimp (Penaeus monodon) is native to the Indo-Pacific and is the second most farmed penaeid shrimp species globally. Understanding genetic structure, connectivity, and local adaptation among Indo-Pacific black tiger shrimp populations is important for informing sustainable fisheries management and aquaculture breeding programs. Population genetic and outlier detection analyses were undertaken using 10,593 genome-wide SNPs from 16 geographically disparate Indo-Pacific P. monodon populations. Levels of genetic diversity were highest for Southeast Asian populations and were lowest for Western Indian Ocean (WIO) populations. Both neutral (n = 9,930) and outlier (n = 663) loci datasets revealed a pattern of strong genetic structure of P. monodon corresponding with broad geographical regions and clear genetic breaks among samples within regions. Neutral loci revealed seven genetic clusters and the separation of Fiji and WIO clusters from all other clusters, whereas outlier loci revealed six genetic clusters and high genetic differentiation among populations. The neutral loci dataset estimated five migration events that indicated migration to Southeast Asia from the WIO, with partial connectivity to populations in both oceans. We also identified 26 putatively adaptive SNPs that exhibited significant Pearson correlation (p < 0.05) between minor allele frequency and maximum or minimum sea surface temperature. Matched transcriptome contig annotations suggest putatively adaptive SNPs involvement in cellular and metabolic processes, pigmentation, immune response, and currently unknown functions. This study provides novel genome-level insights that have direct implications for P. monodon aquaculture and fishery management practices.

“…Despite extensive knowledge about its life cycle (Carvalho et al, 2015;Boos et al, 2016), there is still a lack of information regarding its estuarine phase (Alfaro-Montoya, 2010). We highlight the studies of Chu et al (1995) in a Chinese estuary, Pérez-Castañeda and Defeo (2002) in a Mexican coastal lagoon and Kaka et al (2019) that approached both estuarine and marine areas from Kenya. The lack of fisheries data regarding its abundance, especially regarding small-scale fisheries, is one of the reasons that made the species be considered as data deficient in Brazil according to the IUCN (International Union for Conservation of Nature) criteria (Boos et al, 2016).…”

Shrimps are one of the world’s most valuable fishing resources, with the Penaeidae family having the greatest economic importance. In the southwest Atlantic the white shrimp Litopenaeus schmitti plays an important socioeconomic role for small-scale fisheries, and juveniles are targeted as live bait for recreational fisheries. This study was carried out monthly along two periods (May/2009‑January/2010 and March/2011-March/2015) at Santos estuary and aimed to investigate the relationship between morphometric and sex of the early development stages of Litopenaeus schmitti. A total of 6,978 individuals were caught and measured, with no differences (p>0.1) between sexes shown regarding total length or weight. Differences between males and females were found for Total length (TL) x Carapace length (CL) and TL x Total weight (TW) and negative allometries (b<3) were found for all relationships. The results indicate that morphometric differences among sexes seem to be more associated with total length, suggesting that TL could be a more appropriate body measurement to compare specimens of L. schmitti, at least when the analysis includes juveniles. The presence of L. schmitti specimens all year long inside the estuary reinforces the idea of a continuous reproductive cycle with peak periods. Both information comes to fulfill part of the lack of knowledge regarding this species estuarine phases.

“…The spines on the rostrum section are commonly used to assess the meristic characteristics of Macrobrachium species and are the main taxonomic characteristics used to identify freshwater prawn species (Wowor and Ng 2007;Adite et al 2013;Chen et al 2015;Kaka et al 2019). The number of serrations under the rostrum (ventral) in almost all male and female specimens was the same.…”

Abstract. Jurniati, Arfiati D, Andriyono S, Hertika AMS, Kurniawan A, Tanod WA. 2021. The morphological characters and DNA Barcoding identification of sweet river prawn Macrobrachium esculentum (Thallwitz, 1891) from Rongkong watershed of South Sulawesi, Indonesia. Biodiversitas 22: 113-121. Freshwater prawns of the genus Macrobrachium Bate, 1868 (Crustacea: Palaemonidae), play an essential role in freshwater ecosystems. Apart from being a crucial biotic component, freshwater prawns are also an important fishery commodity. The sweet river prawn Macrobrachium esculentum (Thallwitz, 1891) is a freshwater prawn that inhabits the Wallacea area and is a key constituent of crustacean biodiversity. However, morphological studies on Macrobrachium prawns that inhabit Sulawesi are still minimal. This study is the first report on the morphological and DNA barcoding identification of freshwater prawn M. esculentum downstream of the Rongkong watershed in South Sulawesi, Indonesia. The morphological characterization includes morphometric and meristic characteristics and is complemented by the DNA barcoding of the cytochrome c oxidase subunit I (COI) region. The analysis of the morphometric characteristics showed the formation of two population groups: the Waelawi River group and the Salujambu-Pombakka Rivers group. However, the meristic characteristics of M. esculentum from the three rivers were not significantly different. Meanwhile, the DNA barcoding analysis confirmed that the samples collected from the three rivers belong to the same species. This study provides information on the identification of M. esculentum inhabiting the Rongkong watershed and its population characters and grouping based on morphometric and meristic characteristics. This information can contribute to the management of fishery resources and the conservation of M. esculentum prawn resources in the Rongkong watershed, South Sulawesi, Indonesia.
