Aquacultural Engineering 

TL;DR: This review aims to summarize the most recent developments within RAS that have contributed to the environmental sustainability of the European aquaculture sector and identifies the key research priorities that will contribute to the future reduction of the ecological impact of RAS.

TL;DR: Although studies on the application ofdenitrification in freshwater and marine recirculating systems were initiated some thirty years ago, a unifying concept for the design and operation of denitrifying biofilters in recirculate systems is lacking.

TL;DR: The principle advantages of photosynthetic suspended-growth systems are lower capital costs relative to other recirculating aquaculture systems and increased control over stock management relative to conventional static ponds and the main disadvantage is the relatively low degree of control over water quality and phytoplankton density, metabolism, and community composition.

TL;DR: This paper describes the fundamentals of the moving bed biofilm reactor and has a major emphasis on nitrification with the type of biofilm carrier used in fish farms, but briefly touches upon removal of organic matter and denitrification.

TL;DR: A novel technique was developed for the flocculation of marine microalgae commonly used in aquaculture, and concentrates prepared from 1000 L Chaetoceros muelleri cultures were effective as supplementary diets to improve the growth of juvenile C. gigas and the scallop Pecten fumatus reared under commercial conditions.
