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

Table 3

Length-to-length relationships (LLRs) of the species (all), females only, and males only, based on the equation LOG (TL) = LOG (a) + (b) LOG (SL), where (a) is the intercept and (b) is the angular coefficient. N is the sample size, (TL) is total length in cm, and (SL) is standard length in cm. 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	0.67465	0.66624–0.68318	1.04	1.03–1.04	0.9860
Juveniles	418	0.67698	0.65756–0.69696	1.03	1.01–1.05	0.9599
Females	269	0.74192	0.68891–0.79902	0.99	0.95–1.03	0.9016
Males	478	0.65490	0.62815–0.68279	1.05	1.03–1.07	0.9512
