The paper quantifies catch inequality in California steelhead fisheries using 11 years of angler report data, finding high inequality and developing a method to determine minimal sample sizes for robust Gini coefficient estimation.

The study tests if field preparation methods in agricultural floodplains affect survival and growth of juvenile Chinook salmon, finding no significant differences among treatments.
