The article deals with the problems of regulating commercial fishing in the water bodies of Kazakhstan. Analysis of data on fishing in large reservoirs of the Republic of Kazakhstan shows that along with natural changes in the fish stocks (when the water level in the reservoir decreases), the fishing intensity makes the greatest impact on the state of fish stocks. Today a pre-existing limiter as the fishing regime (the number of fishing gear and fishermen) completely has fallen out of the fishing control mechanisms. According to some reports, the catch of fish with fishing gear available to fishermen, increases the established limits by 1.5–2 times. Thus, the possible catch significantly exceeds the registered (official) catch. It is proposed to use the regulation of the fishing regime (the number of fishing gear, fishing vessels, fishermen) as a measure that determines the limits of safe effort and to limit unrecorded fishing on water bodies. The number of fishermen in the pond should not only meet the criteria for safe effort, but also allow fishing organizations to conduct profitable fishing. The calculation of the maximum allowable number of fishing performance indicators (limit reference points of fishing effort) are given.
