Study Notes
Pest and Predator Control in Nursery Ponds
- Definition of Pest: A detrimental plant or animal impacting human concerns such as crops and livestock. In pond ecosystems, pests compete for resources like feed, dissolved oxygen, and other nutrients critical for fish growth.
- Definition of Predator: An animal that hunts, kills, and consumes other animals within the pond ecosystem.
Methods for Controlling Predators
-
Pond Poisoning:
- Application of pesticides by spraying the pond bottom in at least 0.5 to 1.0 feet of water is common for total elimination of predators.
- Avoid applying poison to a drained pond to prevent residue adhering to the soil, complicating future cleaning efforts.
-
Types of Pesticides:
- Organic: Environmentally friendly alternatives.
-
Chemical: Divided into
- Biodegradable
- Non-biodegradable
Mechanical Removal Techniques
- Draining and Drying: Effective method to eliminate predators. Allows freshwater species buried in mud to resurface after letting water in and draining it out after a few days.
- Screened Gates: Installation of gates to block predators and unwanted fish species from entering the pond.
Chemical Methods
- Pesticide Usage: Should only be used after physical methods fail or when conditions prevent thorough drying of the pond.
- Preference for Organic Pesticides: Recommended due to their biodegradable nature; ensure to read and follow container instructions for safety.
Additional Predator Control Techniques
- Fine-Weave Netting: Acts as a physical barrier to deter snakes and protect fish from predation.
- Fences: Physical barriers around the pond to prevent animal entry.
- Fishstock Guardians: Individuals assigned to monitor and protect the fish.
- PIR Sensors: Use sensors to detect unwelcome arrivals, triggering appropriate responses.
