- Notes: The best GAMLSS model was selected using a stepwise procedure and the lowest values of AIC and global deviance. The independent variables (those without cs) had a linear relationship with the dependent variables
- Abbreviations: ACEN, acenaphthylene in water; ASUMALI, sum of aliphatic hydrocarbons in water; cs, cubic spline smooth function; df, degrees of freedom; FE, fishing effort; ICTABU, ichthyoplankton abundance; LT, fish total length; NOFISH, number of fish per sampling station; NO3, nitrates concentration in water; SANTR, anthracene in sediment; SSUMPAH, sum of polyaromatic hydrocarbons in sediment; S235TRI, 2,3,5, trimethylnapthalene; ZONE, fishing zone in the Yucatan Peninsula; ZOO, zooplankton volume in water
