The research aimed, in general, to estimate the productive and economic efficiency, and to evaluate the performance efficiency of the fishing boats operating in the Bear craft within Lake Bardawil in North Sinai Governorate, Egypt. The problem of the study is the decrease in the amount of fish caught in North Sinai Governorate from the Mediterranean from about 2373 ton in 2007 to about 1952.5 ton in 2020, a decrease of about 17.7%. The quantity of fish caught in Lake Bardawil also decreased from about 4,729 ton in 2007 to about 1,593 ton in 2020, a decrease of about 66.3%. The research reached several results, including: The general average of the boat's share of fixed and variable costs was about 20.49, 45.52 thousand LE., representing about 31.04% and 68.96% of the total fishing costs, at the level of the total sample boats during the 2021 fishing season, as it was found. The amount of optimal and profit-maximizing fish caught amounted to about 4,186 and 5,000 kg, which is more than the actual catch amounting to about 2,875 kg, which indicates that there is a lost income for the boat during the 2021 fishing season. The research recommends the need to provide all the necessary production elements that reach by producing to the ideal quantities and maximizing profits, taking into account the fishing effort in the lake.
