Why Fish Supply Changes During the Rainy Season

Have you ever noticed that some seafood varieties become less available during the rainy season? Changes in fish supply are a natural part of the fishing and aquaculture industry, influenced by weather conditions, water quality, and fishing activities.

According to the Department of Science and Technology (DOST), one of the main reasons is rougher seas and stronger winds. During periods of heavy rainfall and tropical weather disturbances, fishermen may be unable to go out to sea safely. Fewer fishing trips often mean a lower supply of fresh fish reaching markets.

Rainfall can also affect fish farms and aquaculture operations. Sudden changes in water temperature, salinity, and oxygen levels can impact fish growth and harvesting schedules. Farmers may delay harvests to ensure the health and quality of their stocks.

In addition, some fish species become more difficult to catch during the rainy season as they move to different areas or depths in response to changing environmental conditions (Dieter Melhorn Fishing, 2019). This can affect the availability of certain seafood products throughout the season.

As supply decreases while consumer demand remains steady, market prices may fluctuate. This is why some seafood varieties may become more expensive or harder to find during extended periods of rain.

Despite these seasonal changes, proper cold chain management, responsible aquaculture practices, and sustainable sourcing help ensure that high-quality seafood remains available year-round. By understanding how weather affects the seafood industry, consumers can better appreciate the journey that seafood takes from the water to their table.
