Weight-Length and Length-Length Relationships of the Endangered Zebra Pleco Hypancistrus zebra (Siluriformes, Loricariidae) from the Xingu River, Amazon, Brazil

Table 2

Weight-length relationships (WLRs) of the species (all), juveniles only females only, and males only, based on the equation LOG (W) = LOG (a) + (b) LOG (TL), where (a) is the intercept and (b) is the angular coefficient. N is the sample size, (TL) is total length in cm, and (W) is weight in g. CL is the confidence limits, and R² is the coefficient of determination.

	N	(a)	95% CL a	(b)	95% CL b	R ^2
All	1165	0.00648	0.00622–0.00675	3.22	3.20–3.25	0.9848
Juveniles	418	0.00881	0.00813–0.00954	2.98	2.93–3.04	0.9600
Females	269	0.01441	0.01165–0.01783	2.81	2.69–2.92	0.9003
Males	478	0.00550	0.00472–0.00640	3.31	3.23–3.39	0.9354
