New Record of Macrobrachium lar (Fabricius, 1798) (Crustacea: Decapoda: Palaemonidae) from Al-Hammar Marsh, Southern Iraq

Abstract

A species of freshwater prawn Macrobrachium was newly recorded from Al-Hammar marsh, Southern Iraq. Morphological features accompanied by 18 S r DNA analyses indicated that the species is Macrobrachum lar. DNA sequences of specimens of this species from the marsh is deposited at the GenBank for DNA as a new global isolate and was published by The National Center for Biotechnology Information (NCBI), the European Nucleotide Archive (ENA) and DNA Data Bank of Japan (DDBJ). M. lar inhabit deep sections of streams and brackish water, adults live in freshwater, while juveniles can be found in brackish or saltwater, the total length of M. lar recorded in this study was ranged between 72 and 109 mm for males and between 61 and 93 mm for females.

New record of Macrobrachium equidens shrimp (Dana, 1852) (Crustacea: Decapoda: ‎Palamonidae) as invasive species in Al- Mashaab River, East of Al- Hammar marsh, ‎Southern Iraq

“…This investigated description the first record of M. equidens, in Al-Hammar marsh, Southern Iraq. Several of new species of freshwater Macrobrachium were recorded in Iraq water, and M. equidens the third invasive species of Macrobrachium to be recorded in the Iraq water, after the Macrobrachium nipponense (Salman et al, 2006) and recently Macrobrachium lar (Ghazi and Hassan, 2021). In this study, presents a differential characterize of the morphological and confirmed with DNA barcoding, mitochondrial analysis COI gene was the most important key to confirm the species under this study.…”

“…Genus Macrobrachium Bate, 1868 (Palaemonidae) have more than twohundred and forty two species and subspecies live in different aquatic environments (De Grave and Fransen, 2011) Macrobrachium is originated in many countries excluding in Europe (Holthuis and Ng, 2010). Based on previous studies, taxonomic records of Macrobrachium from Iraq back to 2006, the first record was by Salman et al (2006) who reported Macrobrachium nipponense, and second species which Macrobrachium lar (Ghazi and Hassan, 2021). According to Choy (1984) Macrobrachium equidens has been founded in large area such as India, Southeast Asia and Islands.…”
