Remarks Mass = 46.4 kg; mean total length = 30.1 cm ± 9.1; 18.6% were discarded due to size. A complementary survey, using an aerial-roving design, was conducted to assess recreational shore fishing. Aerial surveys were conducted twice a month to obtain instantaneous counts of the anglers in the whole sampling area (with dates, starting time and flight direction randomly selected to minimize visibility bias). Flights were conducted at low altitude (150-200 m) and speed (c. 150km/hr). Roving creel surveys (on-site angler surveys during which angler's harvests were examined) were conducted following a non-uniform probability of sampling, with probabilities assigned to each section based on mean effort data of the previous months (from aerial surveys) (Ref. 85154).
