Geert, Can you get a simpler model with, say, a quadratic dependence on lon, lat to converge, using glmmPQL? The answer might give a clue about whether the issue is related to using a smoother, or is something more basic. How confident are you that the Poisson assumption is reasonable? Can

[R] convergence problem gamm / lme

Hope one of you could help with the following question/problem: We would like to explain the spatial distribution of juvenile fish. We have 2135 records, from 75 vessels (code_tripnr) and 7 to 39 observations for each vessel, hence the random effect for code_tripnr. The offset (‘offsetter’)
