What RAS can do for humans and the environment

If you haven’t heard about Recirculating Aquaculture Systems (RAS) yet or are not quite sure about the specs of this technology, this article is for you! At Blue Planet Ecosystems, we are working on a new RAS solution that we call “LARA” (Land-based Automated Recirculating Aquaculture). For us as a startup company, it is important to educate people about the advantages but also challenges that come with operating such a system. Only if we start to understand how our food is being produced and what differentiates one method from another, we will be able to make better choices.

A comparison of common aquaculture methods to farm fish

Across industries, an increasing number of consumers attach greater importance to environmental and ethical implications of animal products. One prime example is the consumer demand for free-range eggs.

People sometimes tend to romanticize fishery practices. Small fisher boats, hand lines and the fresh, wild catch? …


If you are one of the meat and fish eaters who is concerned about the environment but not ready to shift to a vegetarian or vegan diet (yet), you might want to take the first step and reduce your carbon footprint by following a pescetarian diet. As the name suggests, pescetarians add fish and seafood to their otherwise exclusive vegetarian diet.

Why is a pescetarian diet more eco-friendly?

One of the main reasons is the low feed conversion ratio fish has compared to meat. The feed conversion ratio describes the amount of feed that is necessary to produce 1kg of…
