One of the biggest challenges in the aquaculture industry is meeting growing demand for fish. With the increase in consumption, also increases the cost of fish meal, the basis of the feed that feeds them. Higher cost of production means higher price for the final consumer.

The downside of providing vegetable diets to fish is that their metabolism changes, they retain more fat and thus become less tasteful than wild fish. The research concluded however, that although sea bass are carnivorous, they tolerate up to 30% of their vegetarian diet without detriment to their growth.
Further studies are needed to identify the fat retention mechanisms in fish fed with this diet. Genetic selection is one of the alternatives to be studied. Even so, the discovery is quite promising, as it signals a future with quality fish with lower cost. Good for the producer, good for the consumer.
Ruganzu Bruno, while still an art student at Kyambogo University in Uganda, dreamed of being an artist like Picasso. One day he saw children playing in one of his garbage sculptures in the city. He realized then that he should shift the focus from the sculptures to playgrounds.
A team of researchers from the Universidad Politécnica de Madrid in conjunction with the University of Florence has developed a robot that monitors the quality of water and moves like a real fish.
