Ras Technology

Making Aquaculture Sustainable

Closed loop, bio-secure Recirculating Aquaculture System technology can offer significant benefits over traditional aquaculture production methods, whilst being cost effective and scalable, as well as sustainable and geographically independent.

The Problem

Increased seafood consumption is up against increasing issues faced by wild catch and traditional aquaculture

Prone to environmental issues
  • The general population of marine resources is declining; the world’s wild fish stocks are over-exploited.
  • Farmed fish associated with biological problems which bring negative impacts to the environment such as water pollution
Environmentally unsound
  • Changes in climate and water quality will directly affect the population of wild fish stock.
  • Farmed fish production is limited by environmental conditions such as protected marine sites and steady currents.
Product quality
  • Wild fish may have significantly higher levels of mercury that will be toxic to humans.
  • Farmed fish have been given antibiotics to prevent the disease from spreading in captivity.
Limited by geography
  • Production locations for traditionally farmed fish are dictated by climate, with suitable areas reaching maximum production capacity
Seasonal harvest
  • The current level of wild catch is unsustainable. Wild fish populations are getting smaller, but demand is staying at the same level.

RAS technology providing the solution

Environmental benefits

Significantly reduced water pollution from feed, feces and chemical waste.

Year-round harvesting

RAS systems allow for easier control of supply, including ability for partial or staggered harvesting, compared to traditional cage systems.

Location independent

Ability to locate close proximity to the market – resulting in lower GHG emissions from transport, cost savings & longer shelf life.

Full bio-security

Zero risk of farmed fish escaping into the wild, and zero need for antibiotics or chemical treatment.

Faster growth

Ability to constantly control water parameters, maintain optimum oxygen / CO2 levels, and higher feed conversion rates, facilitates a faster salmon growth rate as compared to the wild.

Production cost advantage

Significant cost of production advantages compared to traditional cage farming, including no requirement for expensive sea net licences.

shrimp solutions

We develop cost-effective and efficient small to medium-scale Recirculating Aquaculture Systems (RAS) for a number of aquaculture species, with a patent pending specifically for Whiteleg shrimp production.

Bloom’s indoor RAS facilities provide full-scale solutions for commercial, intensive and sustainable shrimp production, including sophisticated water treatment systems to recirculate water in a closed-loop system, requiring zero chemicals or antibiotics.

Introducing shrimp – healthy protein seafood vs. other sources

Compared to other types of seafood, shrimp provides substantial advantages in nutrition with the highest iron and 2nd lowest total fat and calories which is suitable for weekly consume.
