Fishery has developed rapidly because the fish feed extruder was born. Up to now, there has been a marked increase in the use of extruded diets for feeding fish. These diets have superior water stability, better floating properties and higher energy than pelleted diets.
The technology development has significantly increased utilization of oil palm frond and other by-products from oil palm industries. The use of oil palm frond as the main fiber source in ruminant rations has markedly reduced feeding cost between 20-30%.
Due to the increase on cost of conventional fuel (such as coal, wood and natural gas) and the need for new energy resources, more people start to focus on Biomass fuel business.
