Fish play a crucial role in estuaries by contributing to the ecosystem's health and balance. They help control populations of smaller organisms and serve as prey for larger predators, promoting biodiversity. Additionally, fish contribute to nutrient cycling through their feeding habits and waste, supporting the growth of plants and algae. Their presence also attracts other wildlife, enhancing the overall productivity and ecological integrity of the estuarine environment.
Sedimentation in estuaries can decrease water clarity, smother benthic habitats, and alter nutrient cycling. Excessive sedimentation can also clog fish gills, impacting fish health and reducing biodiversity in the estuary.
Damming a river will affect the estuary at the river's mouth by lowering the amount of water passing through the estuary. This can cause the loss of habitat and nursery areas for small fish, birds, and even sharks.
Why is an estuary used as a nursery for the younng of many saltwater fish
Yes

An estuary is a lake or river with a mixture of fresh and salt water(mostly near the sea). You would find freshwater fish and some species of saltwater fish in an estuary. There are also some marine toads\frogs and a few water insects.
Living things in an estuary include fish, birds, crabs, and plants like seagrass. Nonliving things in an estuary include water, rocks, sediment, and sunlight.
Estuary ecosystems serve as nurseries for approximately 75% of commercial fish species. These sheltered areas provide important habitat for juvenile fish to grow and develop before moving out to the open ocean.

Biotic factors in an estuary refer to the living components of the ecosystem that influence its structure and function. These include a diverse range of organisms such as fish, birds, invertebrates, aquatic plants, and microorganisms. The interactions among these species, including predation, competition, and symbiosis, play a crucial role in the health and stability of the estuarine environment. Additionally, the presence of these organisms can affect nutrient cycling and energy flow within the estuary.
