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.
