Health warning over plant based feeds

PLANT based fish feeds could have a negative impact on the environment as well as providing diets lacking in omega-3, a study published in the Environment International journal concludes.

Aquaculture’s environmental footprint may now include nutrient and pesticide run-o from industrial crop production, and depending on where and how feed crops are produced, could be indirectly linked to associated negative outcomes,’ the study said.

Jillian Fry, director of the Public Health and Sustainable Aquaculture Project at America’s John Hopkins University and a contributor to the study, said the plant-based ingredients have to come from somewhere and as it gets to a larger and larger scale, then that environmental footprint gets quite large’.
