A multigear protocol for sampling crayfish assemblages in Gulf of Mexico coastal streams


Identifying an effective protocol for sampling crayfish in streams that vary in habitat and physical/chemical characteristics has proven problematic. We evaluated an active, combined-gear (backpack electrofishing and dipnetting) sampling protocol in 20 Coastal Plain streams in Louisiana. Using generalized linear models and rarefaction curves, we evaluated environmental and gear (separate and combined) effects on crayfish catch-per-uniteffort (CPUE), orbital carapace lengths, sex ratios, frequencies of rare species, and sample richness.
