Sea bream

Gilthead sea bream (Sparus aurata) is the most commonly farmed species, especially in Mediterranean aquaculture. It is a marine, euryhaline species, meaning it can adapt to various salinity levels. Sea bream are omnivorous, robust, and well-suited for farming in coastal and offshore environments, making them a staple of warm-water aquaculture in Europe, North Africa, and the Middle East.

All feed formulas developed by Aller Aqua at the Aller Aqua Research Centre follow these requirements to ensure proper growth and health:

  • High-Protein Diet: Diets typically contain 40–45% protein to support growth, feed efficiency, and body development. Protein sources include fishmeal, soybean meal, wheat gluten, and other plant-based concentrates. Feed formulations are adjusted by life stage, with higher protein ratios during juvenile phases.

  • Fat and Energy Needs: Fat content ranges from 12–20%, depending on growth stage and water temperature. Energy is supplied through a mix of fish oil and plant-based oils, like rapeseed and sunflower. Proper energy-to-protein balance improves growth performance and maintains good flesh quality.

  • Essential Nutrients: Feeds are enriched with vitamins A, D, C, and E to support immunity and antioxidant defense. Minerals such as phosphorus, calcium, zinc, and selenium are included for bone and metabolic health. Omega-3 fatty acids promote cardiovascular health in consumers and improve fish stress resistance.

The range of solutions developed by Aller Aqua is suitable for each stage of the fish lifecycle as well as the following farming methods:

  • Sea Cages (Marine Net Pens): Most common method — fish are grown in floating cages in coastal or offshore areas.

  • Land-Based RAS (Recirculating Aquaculture Systems): Increasingly used for juvenile production and biosecurity, especially in hatcheries.

  • Hatcheries: Eggs are produced and fry are raised in hatchery tanks before transfer to grow-out cages.

  • Polyculture Systems: Sometimes combined with other marine species like sea bass or mussels in integrated aquaculture systems.

A carefully selected composition of raw materials and verified feed formulas ensure that the fish is rich in minerals and vitamins, and at the same time that the texture of meat is of the highest quality. We make sure that fish grown using solutions provided by Aller Aqua offer the following benefits:

  • Delicate Taste & Firm Texture: Sea bream is a popular table fish known for its white, flaky flesh and mild flavor.

  • Nutritional Value: High in lean protein, omega-3 fatty acids, vitamin D, and selenium.

  • Heart-Healthy: Omega-3 content supports cardiovascular health and reduces inflammation.

It is commonly found in supermarkets and restaurants; great for grilling, baking, or steaming.
