Abstract

Authors' Contribution QMD, TTHL and YTNN conceived and developed the study. QMD, YTNN and TMN conducted fieldwork and contributed to data collection. QMD, TTHL and TTKN performed the analysis. QMD and TTHL wrote the manuscript. QMD, TTHL, YTNN and TTKN contributed to editing the manuscript.

The use of mtCOI gene sequences in identifying Butis species in the Southwest of Vietnam

“…This demonstrated that the efficiency of DNA barcoding in species identification was high. In the same way, several previous studies showed that the body sizes of B. humeralis in TDST were larger than in HBBL [ 9 ] and also that DDCM was the sampling site where TL and W values of B. butis were lower than HBBL [ 10 ]. However, in clusters III and IV, they were grouped.…”

“…Morphometric and meristic parameters, including fish weight (W), total length (TL), body depth (BD), head length (HL), eye diameter (ED), the distance between eyes (DE), ED/HL, DE/HL, BD/TL, HL/TL in previous studies [ [8] , [9] , [10] ], were re-analyzed in the present study. The Shapiro-Wilk test examined the normal distribution of these parameters [ 36 ].…”

“…Yet, it is difficult to distinguish between B. humeralis and B. butis due to their similar exterior traits such as blackish body colour [ 7 ], the slightly flattened head, the long and pointed snout, and a pair of serrated bones within the interorbital spaces [ 3 ]. Several articles related to the morphology and morphometrics of Butis species in the VMD have recently been published [ [8] , [9] , [10] ]. These studies have revealed that the species reaches different average body sizes over four different sampling sites.…”

Otolith morphometry and its role in determining the growth of Periophthalmus chrysospilos distributed in some coastal provinces in the Mekong Delta

“…chrysospilos spawns all year round, highly concentrated in the wet season (July to October). According to Dinh et al (2022a), the fecundity of the batch ranges from 2,614 to 23,465 eggs/female and is proportional to the fish's total length and body weight. Ps.…”

Food and Feeding Habits of Mystus tengara (Hamilton, 1822) of Gomati River and Rudrasagar Lake, Tripura, India

“…"During the breeding season, females have swollen abdomen while in males, the genital papilla (which is present only in males) becomes very prominent. The success of good scientific planning and management of fish species largely depends on the knowledge of their biological aspects, in which food and feeding habits include a precious portion" [6,7]. The study of food and feeding habits of fish have manifold importance in fishery biology and fisheries management, it was playing crucial role in day to day fish conservation practices has been proven earlier scientific works [8,9].…”
