Resumen
The present communication is based on the report of a single specimen of spot-fin porcupine fish, Diodon hystrix Linnaeus, 1785 from the Hooghly-Matlah estuarine system which is a new record to the systems. The specimen was collected from a bag net catch during February 2021 at Fraserganj fishing areas of the lower stretch of Hooghly-Matlah estuarine systems, India. The size of the specimen was recorded as 280.13 mm in length, 235 g in weight, and big eyes with 18.23 mm in diameter. The fish specimen was also sequenced (barcoded) for a 655 bp region of the mitochondrial cytochrome oxidase subunit 1 (cox1) gene and submitted to the GenBank with accession number MZ665467. Being a marine species, previously this species was reported from the trawl net catch of Bay of Bengal, West Bengal, India, but not from any estuarine environments including Hooghly-Matlah estuarine systems. Average salinity of 26.3 ± 0.87 ppt was recorded at the site of collection. This first confirmed record of D. hystrix from the Hooghly-Matlah estuary of West Bengal, India is based on both standards’ taxonomic keys-based identification as well as molecular characterization.
