Abstract
The environmental footprint of mariculture is a major obstacle towards expansion of this agro-industry. Additional economic
constraints are the high costs of effluent treatment and expensive, non-sustainable ingredients in aquafeeds. Both Ulva and
periphyton reveal great potential in nitrogen removal in mariculture effluent. To overcome the relatively minor uptake of nitrate by
Ulva, a periphyton-based biofilter can be used either as a stand-alone biofiltration unit or as a polishing unit in an integrated Ulvaperiphyton
biofilter. The biomass produced is rich in protein and is suitable for feeding of marine fish, served fresh on the plastic
net substrate or included in pelleted aquafeeds to replace fishmeal.
