Abstract
AbstractPolychaetes are marine annelid worms that can contribute to aquaculture diversification. Its culture has been viable, and commercially attempted, but intensive production has progressed only in few countries around the world. In the countries with no production, marine polychaetes are imported or harvested. A strong and sustained research investment provided to a better understanding of the nutritional requirements and reproduction of some species. Recent studies showed new technical improvements, which can lead to an important progress in productivity and give a new impetus to the polychaete production. Some marine worm species were identified as good candidates for integrated multitrophic aquaculture. The development of cost‐effective aquaculture techniques for marine annelid worms is essential to ensure a balance between commercial interests and the preservation of ecosystems. The influence of polychaete aquaculture on the environment and vice versa raise important concerns related to ecological security and sustainability of this activity. This review focus on the main technical improvements and advances that have been made in areas as diverse as: aquaculture potential of polychaetes, reared species, main species used worldwide, and highlights biological and ecological concerns, important challenges and recommendations.
Highlights
Marine annelid worms harvesting on sediment shores is an ancient activity and has been an integral part of global coastal life
This review aims to integrate relevant information on the state and the potential rearing of polychaetes, core technical improvements and production advances, main used species worldwide and environmental concerns related to harvesting and dumping activities
Research that allowed knowledge to produce new native species can enhance the diversification of the bait produced, develop simple inexpensive systems for rearing juveniles (García-Alonso et al, 2013), extend of breeding season and/or cryopreservation of larvae to achieve larval supply all year round, develop appropriate breeding protocols (Nesto et al, 2018), optimize growth through control of nutrition with new diets (Santos et al, 2016), temperature and, if appropriate, photoperiod (Olive, 1999), all contributing to improve the production of polychaetes
Summary
Marine annelid worms harvesting on sediment shores is an ancient activity and has been an integral part of global coastal life. Nowadays, this activity has been widely spread, since these organisms are a highly efficient bait. Marine annelid worms are key prey species for aquatic organisms, including economically important fish (e.g. sole) and invertebrates (e.g. shrimps) (Olive, 1994; Dinis et al, 1999; García-Alonso et al, 2008; Garcês & Pereira, 2011; Arias et al., 2013). This review aims to integrate relevant information on the state and the potential rearing of polychaetes, core technical improvements and production advances, main used species worldwide and environmental concerns related to harvesting and dumping activities
