Management of Aquatic Pests in Pensacola

Aquatic Pests-understanding

Aquatic pests are those life forms that infest a water body, harming the ecosystem as well as fisheries and human activities. The humid warm climate in Pensacola is complemented by the long coastline with freshwater areas, making the place very conducive for pest infestation. These pests come as invasive fish, insects, plants, and microorganisms that tend to disturb the balance of the water bodies.

Common Aquatic Pests in Pensacola

1. Mosquito Larvae (Culicidae spp.)

• They thrive in water bodies stagnant like ponds, marshes, or storm drains.
• Increase mosquito populations, which carry health disease risks.
• Can be controlled with larvicides and by the introduction of natural predators such as fish.

2. Water Hyacinth (Eichhornia crassipes)

• An invasive floating plant forms dense mats on the surfaces of water.
• Block the sunlight; deplete levels of oxygen, and disturb the aquatic life.
• Contain manual removal, herbicides, and biological control using hew weevils.

3. Hydrilla (Hydrilla verticillata)

• A submerged rapidly grows plant, which clogs water bodies.
• Navigation problems, hindrance to fishing, and competes adversely with the native vegetation.
• Controlled through mechanical harvest, introduction of herbicides and sterile grass carp.

4. Zebra Mussels (Dreissena polymorpha)

• Small invasive mussels that attach themselves to boats, pipes, and even aquatic structures aside from filter-feeding nutrients that eventually disrupt ecosystems and would harm native species.
• Boat cleaning and chemical treatment are two preventive measures.

5. Giant, Invasive Apple Snails (Pomacea spp.)

• These large, invasive snails munch on aquatic plants to destroy them and damage wetland ecosystems. Its strikingly bright pink egg masses can be seen on vegetation bordering water.
• Manual removal and habitat management can control it.

Signs of Aquatic Pest Infestation

1. Algal Bloom and Dark Water

• A high growth of algae can reveal one indication of the invasive aquatic plants or an imbalance in nutrients.
• Can cause fish kills as a result of depletion of oxygen.

2. Waterways and Drainage Blocked

• The invasive plant growth includes water hyacinth and hydrilla clogs canals, ponds, and drainage ways.
• May lead to increased chances of flooding during storm periods.

3. Unusual Namesake of Decline in Native Fish and Wildlife

• Invasive species -- zebra mussels and apple snails -- could beat native aquatic life to it.
• Imbalance in ecological condition in freshwater and coastal areas of Pensacola.

Aquatic Pest Control and Prevention in Pensacola

1. Biological Control Methods

• Introducing natural predators like grass carp for the control of invasive plants.
• Encouraging native fish species that prey on mosquito larvae.

2. Mechanical Removal and Habitat Management

• Periodic clean-up of ponds and lakes to remove invasive plants and debris.
• Maintain healthy water circulation to prevent stagnation.

3. Use of Herbicides and Larvicides

• Apply approved herbicides from EPA to control Hydrilla and water hyacinth.
• Safe larvicides should be used in mosquito-populated water bodies to reduce breeding.

4. Public Awareness and Prevention Measures

• Educate local communities about invasive species and their impact.
• Encourage boaters and fishermen to clean equipment before entering new water bodies
