Environmental performance of rainbow trout (Oncorhynchus mykiss) production in Galicia-Spain: A Life Cycle Assessment approach.

Aquaculture is an increasingly important supplier of food worldwide. However, due to its high dependence on agricultural and fishing resources, its growth is constantly constrained by environmental impacts beyond aquaculture production systems. Within the European Union, Spain accounts for approximately 25 % of total aquaculture production, which implies that environmental impacts in rivers and marine ecosystems must be monitored to understand the role of aquaculture systems.

Evaluation of the reduction of methane emission in swine and bovine manure treated with black soldier fly larvae (Hermetia illucens L.).

The study evaluates Hermetia illucens larvae's ability to decrease direct methane emissions and nutrients from cattle and swine manure. Hermetia illucens larvae were put into fresh cattle and swine manure, and the same conditions, without larvae, for the control treatment were established. The methane emissions were measured until the first prepupae appeared.
