“…The recent study by Gopalakrishnan et al . (2021) similarly highlighted mislabelled or misidentified samples of threadfins native to India.

“…While all four of these studies recover the most species-rich genus of threadfins, Polydactylus, as polyphyletic, the most recent three studies are only publicly available as abstracts with limited details on their hypotheses. In addition to these four works, studies focused on generating barcode data, mitogenomes or the overall relationships of fishes have, on occasion, sampled multiple threadfin taxa using DNA-sequence characters (e.g., Betancur-R et al, 2013a,b;Gopalakrishnan et al, 2021;Rabosky et al, 2018;Sanciangco et al, 2016) or used a combined-character approach (e.g., Mirande, 2016). Although not the focus of their analysis, the phylogeny of the Polynemidae received some attention by Rabosky et al (2018), who sampled 13 species of threadfins (~30% of species) and recovered the genera Eleutheronema and Polydactylus as polyphyletic, but there are concerns about the data used in their analysis that we will discuss below.…”

Threadfins (Teleostei: Polynemidae) are a group of fishes named for their elongated and threadlike pectoral‐fin rays. These fishes are commonly found in the world's tropical and subtropical waters, and are an economically important group for people living in these regions, with more than 100,000 t harvested in recent years. However, we do not have a detailed understanding of polynemid evolutionary history such that these fishes can be monitored, managed and conserved as an important tropical food source. Recent studies hypothesize at least one genus of threadfins is polyphyletic, and no studies have focused on generating a hypothesis of relationship for the Polynemidae using DNA sequences. In this study, we analyse a genomic dataset of ultraconserved‐element and mitochondrial loci to construct a phylogeny of the Polynemidae. We recover the threadfins as a clade sister to flatfishes, with the most taxonomically rich genus, Polydactylus, being resolved as polyphyletic. When comparing our dataset to data from previous studies, we find that a few recent broad‐scale phylogenies of fishes have incorporated mislabelled, misidentified or chimeric terminals into their analyses, impacting the relationships of threadfins they recover. We highlight these problematic sequences, providing revised identifications based on the data sequenced in this study. We then discuss the intrarelationships of threadfins, highlighting morphological or ecological characters that support the clades we recover.

The paradise threadfin, Polynemus paradiseus is one of the commercially important brackishwater finfish of the family Perciformes in Bangladesh. The present study aimed to investigate the reproductive biology of paradise threadfin from Shibsa River in Bangladesh. The fish samples (66) were collected from May 2021 to April 2022. The relationship between body weight (BW) and total length (TL) of sampled fish were analyzed with a non-linear power equation where R2 = 0.915 and ‘b’ value (3.22) indicates a positive allometric growth pattern. Linear relationship indicates gonad weight (GW) increases with the BW and fecundity increases with BW, TL, GW and gonadosomatic index (GSI). The highest GSI was recorded in June (11.10±0.91), whereas, the lowest in November (0.44±0.08). The maximum fecundity was found in June (32410±7790). Ovarian histology displayed different stages of oocyte development. Late yolk granule stage (LYGS) was found in the months of September-October and May-July, respectively. Based on the GSI, fecundity and ovarian histology, it was revealed that the spawning season of P. paradiseus was from May to October with a major peak in June and minor one in September. The knowledge on different aspects of reproductive biology of paradise threadfin would be helpful for planning captive breeding and to design sustainable management policies for conservation of this species in the south-west coast of Bangladesh.
