Sensor-packed tag gathers more data than ever on giant grouper fish

Despite being related to the humble freshwater perch, the Atlantic goliath grouper grows to be huge – up to 8 feet long (2.4 m) and 800 lb (363 kg). Scientists have recently learned more about its behaviour, using a new multifunctional high-tech tag.Co… Continue reading Sensor-packed tag gathers more data than ever on giant grouper fish

Pineapple skin diet shown to boost growth and immune system of tilapia

Commercial pineapple skin waste typically ends up being composted, or even just dumped in landfills. According to new research, however, a feed additive made from powdered skins has been shown to help farmed tilapia fish avoid infections, plus it repor… Continue reading Pineapple skin diet shown to boost growth and immune system of tilapia
