Activities of Corvina Fish During the Breeding Season

Kelolalaut.com Corvina fish, a popular species found in coastal waters, exhibit fascinating behaviours during their breeding season. Typically occurring in warmer months, this period is marked by changes in movement, feeding habits, and social interactions as they prepare to spawn. Understanding these activities provides valuable insights for both marine biologists and fisheries aiming to conserve and sustainably manage corvina populations.

Migration Patterns

One of the most noticeable behaviours of corvina fish during the breeding season is their migration. These fish move from deeper offshore waters toward shallower coastal areas, estuaries, and river mouths. This migration is influenced by water temperature, salinity, and food availability. Some species, such as the Gulf corvina, travel in massive schools to specific spawning grounds, where they gather in large numbers to reproduce.

Spawning Behaviour

Once they reach their breeding grounds, corvina fish engage in unique spawning behaviours. Males produce loud, rhythmic drumming sounds by contracting muscles against their swim bladders. This vocalization helps attract females and signals their readiness to spawn. The intensity of the drumming increases as more males join the group, creating a chorus that can be heard underwater for considerable distances. This phenomenon is particularly well-documented in species such as the Gulf corvina, where entire schools produce a nearly deafening chorus during peak spawning.

Females, attracted by the calls, release their eggs into the water, where they are fertilized by the males’ sperm. This external fertilization process ensures that millions of eggs are released, increasing the chances of survival for some offspring. However, many of these eggs become food for other marine species, making corvina reproduction a crucial part of the ocean's food web.

Feeding and Energy Reserves

During the breeding season, corvina fish adjust their feeding habits to support the energy demands of migration and spawning. Prior to spawning, they increase their food intake, consuming crustaceans, small fish, and molluscs. This helps them build the necessary energy reserves for reproduction. However, as spawning activities intensify, corvina may eat less, focusing instead on mating behaviours.

Predation and Vulnerability

The breeding season makes corvina fish particularly vulnerable to predators, including larger fish, sharks, and marine mammals. Additionally, human fishing pressure increases during this time, as commercial and recreational fishers target large aggregations of spawning corvina. In some regions, overfishing during the breeding season has significantly impacted corvina populations, raising concerns about sustainability. Conservation efforts, such as seasonal fishing restrictions and catch limits, aim to protect these fish during their most vulnerable period.

Post-Spawning Behaviour

After spawning, adult corvina gradually disperse from their breeding grounds, returning to deeper waters. The fertilized eggs hatch into larvae that drift with ocean currents until they grow large enough to navigate independently. Juvenile corvina often seek shelter in shallow estuaries and mangroves, where they find abundant food and protection from predators.

The breeding season is a crucial phase in the life cycle of corvina fish, influencing their migration, behaviour, and interactions with their environment. Their fascinating spawning rituals, including synchronized drumming and mass migrations, highlight the complexity of marine ecosystems. Effective conservation measures are essential to ensure that corvina populations remain stable for future generations, balancing ecological sustainability with economic interests.
