Table 1. Estimation of the percentage of variation of the Gonad Index (GI) in relation to environmental parameters.

Sea cucumbers	Parameter	% annual variation of GI explained by parameter	n	Spearman’s correlation	P	Regression model
Isostichopus sp.	Temperature (Temp)	24.5%	13	0.555	0.055	GI = (-2.14129 + 0.00359296 * temp²)
	Salinity (Sal)	10.2%	13	0.192	0.502	GI = sqrt (-203143 + 0.0222892 * Sal²)
	Rainfall (Rain)	58.6%	13	0.752	0.001	GI = 1.19406 + 0.293588 * sqrt (Rain)
I. badionotus	Temperature	42%	11	0.645	0.041	GI = 1/(-2.87434 + 92.7004/temp)
	Salinity	10.7%	11	0.373	0.239	GI = 1/(-1.64506 + 73.7991/sal)
	Rainfall	59.2%	11	0.761	0.016	GI = sqrt (5.23381 + 0.00487448 * rain²)
