Keep #s of LMB in certain size categories like 0-8in , 8-12in , 12-15in and larger. Weigh and measure all LMB over 10 inches. On BG same concept 1-3in #s , 3-5in #s and over 5in weigh a few over 5in (largest 10 %). BG have RW also. Do you have BG RW charts? Take pics of some of the fish. A shock survey can sample a lot of fish but no where near all. Depending on time , water conditions , water depth and equipment a rough guess would be 15% of the fish. There would be no benefit of measuring and weighing all the small LMB and small BG. That could take all day. If you like after you get their written report (I assume you will get one) you can post it here for our input and thoughts. Good Luck but more importantly have fun and learn and listen to what they say. Ask questions about water quality , species balance , ageing methods and results and if reproduction #s indicate successful recruitment. Any one else have suggestions ?
