502-506As morphometric information for Hooghly croaker
Panna heterolepis Trewavas, 1977 is absent in the most
extensively accessed and world’s largest online database for fishes
(FishBase); this study was undertaken to provide the complete
informative description on morphometric relationships and
meristic counts of various fin rays. A total of 200 individuals were
sampled from the Bay of Bengal (Bangladesh) during July 2018 to
June 2019, using several traditional fishing gears. Meristic counts
were computed using a magnifying glass. Body weight (BW) and
several length measurements were taken through an electronic
balance and digital slide calipers for each individual. LWRs
(Length-weight relationships) were calculated as: W = a×Lb.
All LWRs and LLRs (length-length relationships) were found
significant with r2 ≥ 0.919 (p < 0.0001) and 0.928 (p < 0.001),
respectively. BW vs. TL and TL vs. SL were the best fitted
models for LWRs and LLRs, respectively. Fin formula was:
dorsal, D. 43–55 (VIII–X+i/34–44); pectoral, P. 15-17 (i/14–16);
pelvic, Pv. 6 (I/5); anal, A. 7–10 (II/5–8); and caudal, C. 17–19
(ii/15–17). These results will a) make a vital contribution for
species identification in the marine and coastal waters of
Bangladesh and adjoining countries, and b) provide information
for Fish Base
