TAC: Catch Limits
-
Definition: Total Allowable Catch (TAC) is the maximum amount of a fish species that can be legally harvested from a specific body of water within a set period.
-
Purpose: TACs are implemented by governments and international organizations to ensure sustainable exploitation of marine resources and prevent overfishing.
-
Importance: TACs maintain a minimum fish population size, allowing for natural replenishment and preventing resource collapse. Without TACs, overfishing can deplete populations, threatening biodiversity, ecosystems, and livelihoods.
-
Indian Context: India uses a seasonal fishing ban (a TAC equivalent of zero) for 61 days annually in its Exclusive Economic Zone (EEZ) to conserve fish stocks during breeding season. East Coast: April 15 to June 14, West Coast: June 1 to July 31.
-
TAC Determination: TAC limits are set by national fisheries authorities or international bodies like FAO or Regional Fisheries Management Organizations (RFMOs).
-
Ecosystem Benefits: TACs prevent overexploitation, supporting marine biodiversity and long-term sustainability of ecosystems.
-
Geopolitical Implications: Disputes can arise over TAC enforcement, as highlighted by the US-Russia disagreement regarding Patagonia toothfish in the South Atlantic Ocean. Russia’s rejection of the established TAC led to individual country limits and subsequent import blocks by the US.
