In Latvia, fishing regulations stipulate a ban on fishing from boats and in specific canals and rivers during the months of March and April to protect fish spawning. This ban is crucial for ensuring the sustainable reproduction of fish populations in local waters. The regulations also prohibit the use of live bait in all waters except for the Baltic Sea and Gulf of Riga, highlighting the emphasis on conservation during this period.

The areas affected by the ban include several river basins: the Daugava, Gauja, and Lielupe, which cover a significant portion of the country's inland water systems. Fishermen are urged to observe these restrictions, as the waters are often still covered with thick ice, making fishing from boats largely impractical at this time. Local authorities continue to monitor compliance with these regulations to safeguard aquatic life and promote ecological balance.

The importance of adhering to these fishing regulations is underscored by the fact that violations can lead to serious legal consequences and threaten the natural resources of fish populations in Latvia. By enforcing this seasonal ban, the government aims to foster a healthier aquatic environment and ensure that fish populations can thrive and maintain their natural reproductive cycles, which are vital for the ecosystem.
