Target Strength Sampling strategy Aggregation of length composition 2. Coverage Distance between transects Overall coverage Sampling unit 3. Day/Night; wind; moon (Under which environmental conditions are the data valid) 4. Identification (biological sampling) 5. Environmental influence 6. Technical performance Threshold Saturation Calibration 7. Statistical design of transects Zigzag Parallel 8. What are the variances of our estimates?
