Production of live prey

The production of live prey is a crucial step in aquaculture, particularly for the rearing of fish larvae, crustaceans, and other aquatic species. It involves cultivating and maintaining live organisms such as rotifers, Artemia, and copepods, which serve as a natural food source for larvae. These prey are rich in essential nutrients and promote healthy and rapid growth in farmed animals. The process requires strict control of water parameters, the nutritional quality of the prey, and culture conditions to ensure optimal and consistent production.

Zooplankton Production for Aquaculture

Zooplankton production is essential for aquaculture, particularly for the rearing of fish, crustacean, and mollusk larvae. Zooplankton serves as a nutrient-rich food source, providing essential fatty acids and proteins, which promote larval growth and survival.

Types of Zooplankton Used in Aquaculture
1. Rotifers (Brachionus sp.)
  - Widely used for feeding marine fish larvae (e.g., sea bass, gilthead seabream).
  - Easy to culture and can be nutritionally enriched.
2. Artemia (Artemia salina nauplii)
  - Highly valued in aquaculture for their nutritional content.
  - Artemia cysts are easy to store and hatch.
3. Copepods
  - Ideal for fish species whose larvae have specific nutritional requirements.
  - More difficult to culture but offer better survival and growth rates.
Zooplankton Production Methods

1. Rotifer Culture
- Culture medium: Filtered and sterilized seawater, temperature 25-30°C, salinity 15-30 ppt.
- Feeding: Microalgae (Chlorella, Nannochloropsis) or commercial substitutes.
- Density: Maintain a stable population to prevent overcrowding and water degradation.
2. Artemia Hatching and Culture
- Cyst incubation: Saline water (25-35 g/L), continuous aeration, temperature 25-28°C.
- Harvesting: After 24 hours, nauplii are separated from cyst shells and fed to larvae.
3. Copepod Culture
- Culture medium: Filtered seawater, optimal temperature depending on species.
- Feeding: Live phytoplankton.
- Production: Longer cycle but necessary for some sensitive marine species.
Production Optimization
- Control of physico-chemical parameters (pH, oxygen, temperature).
- Monitoring water quality (prevent ammonia and nitrate accumulation).
- Nutritional enrichment (fatty acids, vitamins) before feeding larvae.
Zooplankton production is a key factor in the success of larval rearing in aquaculture. Proper mastery of culture techniques ensures high-quality nutritional intake for young aquatic organisms.
