Fishes generally breed with the onset of monsoon. This is also the season when the water levels are at their highest. The tradition of not fishing during these 3-4 months stems from the fact that the fishing communities want to replenish the resources because their livelihood depends on this.
From a scientific point of view, it helps the ecosystem because overfishing can be catastrophic in the long run, leaving no fish at all (in inland waterways at least) in a matter of few years if Fishermen don't take a sabbatical for 3-4 months.

Reasons why people of the village do not go for catching fish for four months:
1. Fish Breeding Season:
- The main reason why people of the village do not go for catching fish for four months is because it is the fish breeding season.
- During this time, fish reproduce and lay their eggs, which requires a peaceful and undisturbed environment.
- To ensure the survival and growth of fish populations, it is essential to avoid fishing during their breeding season.
2. Protecting Fish Stocks:
- By refraining from catching fish during the breeding season, the village community is actively participating in the conservation and sustainability of fish stocks.
- Allowing fish to breed and reproduce without human interference helps maintain the ecological balance of the marine ecosystem.
3. Ensuring Future Fish Supply:
- By giving fish the opportunity to breed and reproduce, the village community is ensuring a future supply of fish.
- Allowing the fish population to replenish itself during the breeding season contributes to a more consistent and sustainable fish supply in the long run.
4. Environmental Awareness:
- The decision to abstain from fishing during the breeding season demonstrates the village community's environmental awareness and commitment to responsible fishing practices.
- By respecting the natural life cycle of fish, they are actively taking steps to preserve the marine environment and its biodiversity.
5. Supporting Local Economy:
- While the villagers may temporarily halt fishing during the breeding season, this period can be utilized for other economic activities related to the sea, such as boat maintenance, repairing fishing nets, or engaging in alternative livelihoods.
- This approach ensures the long-term viability of the local fishing industry and supports the economic well-being of the community.
In conclusion, the villagers refrain from catching fish for four months primarily because it is the fish breeding season. This decision is motivated by the need to protect fish stocks, ensure future fish supply, demonstrate environmental awareness, and support the local economy.
