“7º—As complementary management measures to the sizes at first sexual maturity and at first capture, the following are established:
.
To authorize the use of gillnets or entangling nets (redes agalleras o redes de enmalle) only with a mesh size of 3.5 inches (8.75 cm) and 6 inches (15 cm) in zones 202 and 203 of the Gulf of Nicoya.
In the case of the first mesh size, so that its target catch is the aguada corvinas (corvinas aguadas), picuda corvinas (picudas), and others, while the second mesh size is for the protection of the mega-spawners of queen corvinas, yellowtail corvinas, white and black snook. The application of the previous measure, 6 inches (15 cm), must be implemented as of April 30, 2019, which means modifying all those fishing licenses previously issued with a different type of mesh size. That the Development and Research Department (Departamento de Desarrollo e Investigación) must carry out analyses of the sampling databases by fishing zone and by year, to determine whether there have been changes in the sizes captured for these species, and if necessary, samplings will be carried out on landings made with gillnets of 5- and 6-inch mesh size, to determine which of the two captures a greater number of individuals that have already reached the size at first sexual maturity.
That while this provision enters into force, fishers may use their gillnets of 7-inch mesh.”
