Description
Summary:The continuous high expectations on the world's fisheries to provide products for human consumption is leading to increased overexploitation of fishing stocks. This unsustainable exploitation desperately calls for other suitable resources that can relieve the pressure on the fisheries. The utilization of Calanus finmarchicus has been proposed as a suitable alternative. There is, however, still a question of both ecological and economical sustainability of such exploitation. This review describes currently utilized marine resources, and compares the suitability of C. finmarchicus as a useful alternative for those resources. Additionally, the review describes the life history and chemical composition of C. finmarchicus. Current utilization of C. finmarchicus is also described, along with industrial methods used to derive various products from Calanus, as well as a discussion of other potential products from the resource. C. finmarchicus can potentially be considered an alternative marine resource as it has a unique lipid composition, is rich in antioxidants, and contains diverse enzymes. However, the question of sustainable catching remains unanswered and must be addressed before C. finmarchicus can be considered for utilization. •Calanus finmarchicus is rich in lipids and antioxidants.•Calanus finmarchicus is a potential multipurpose marine resource.•Economic and ecological sustainability have yet to be assessed.
