Since the 1980s, non-algal aquaculture has grown to encompass 49% of all seafood production in response to a growing human population and increased seafood demand (FAO, 2022). Hurdles exist to aquaculture sustainability, including dependence on wild sourced fishmeal (FM) and the impacts wastewater discharge. It takes 4-5 tons of wild forage fish to produce one ton of dry FM (Miles and Chapman, 2006) and as aquaculture is primarily conducted in earthen ponds and public open water bodies (FAO, 2022), finfish culture can have a high impact on the surrounding environment by discharging excess nutrients. This study used algae turf scrubber …

The forest industry is a highly cost intensive business and therefore effective management is necessary. Information about productivity and time consumption of harvesting equipment in a variety of stand and site conditions can help operation managers to be efficient. In the state of Maine there have not been any productivity related publications within the past 25 years. Due to this lack of information and the need of information of productivity, especially in small diameter stands, the presented research developed. The focus of this study is on whole-tree harvesting systems including feller-buncher, grapple skidder and stroke delimber, as well as cut-to-length …
