Weight-length and length-length relationships for 12 saltwater fishes

Weight (W)-total length (TL) relationships were developed for alligator gar (Lepisosteus spatula), Atlantic croaker (Micropogonias undulatus), Atlantic sharpnose shark (Rhizoprionodon terraenovae), Atlantic stingray (Dasyatis sabina), gafftopsail catfish (Bagre marinus), gizzard shad (Dorosoma cepedianum), gulf flounder (Paralichthys albigutta), gulf menhaden (Brevoortia patronus), hardhead catfish (Arius felis), pinfish (Lagodon rhomboides), spot (Leiostomus xanthurus) and striped mullet (Mugil cephalus). Atlantic stingray TL was measured from wing tip to wing tip. Weight-standard length (SL) and TL- SL equations were developed for the above species, except that no TL-SL equations were developed for the Atlantic stingray or Atlantic sharpnose shark. Regression coefficients for equations in the form of Y= a + bX were estimated for log transformed weight as a function of log transformed total length, log W as a function of log standard length and log TL as a function of log SL. Equations developed for species in this study were generally different from those reported in other studies.
