Seaweeds, the Future of Human in the Sea

• Sustainable management
• f fisheries resources
• Conditions with clean,

HABs Development and Fisheries Damages in the South-east coast, Korea

▪ HABs since 1980s ▪ Summer Blooming of Ichthyologic Cochlodinium polykrikoides ▪ Vernal Shellfish Toxification by PSP-producing Alexandrium tamarense

• The great potential of the polychaete worms for bioremediation
• The possibility of water quality improvement

by the polychaete-assisted integrated culture system

Water quality improvement of rockworm, Marphysa sanguinea in the integrated culture system with olive flounder, Paralichthys olivaceus

Integrated culture systems : Flow-through and Semi-recirculation

A) the integrated culture system B) worms at the beginning of study C) transport of fish feces & uneaten feed by siphon into the worm box D) collecting of worms at the end of study E) worms fed on fish feces and uneaten feed F) worms fed on commercial feed

• Fig. Comparisons of growth performance in final weight of rockworm Marphysa sanguinea

according to the size groups when fed on fish feces & uneaten feeds (T1-T3), and commercial diet (T5) in the integrated culture with olive flounder.

Table 1. Wastewater quality improvement by M. sanguinea in the integrated culture with olive flounder for 13 weeks in flow-through system

Table 2. Wastewater quality improvement by M. sanguinea in the integrated culture with olive flounder for 13 weeks in semi-recirculating system

Summary: ❖ The rockworm Marphysa sanguinea could grow readily by feeding on fish feces and uneaten feed of flounders as a food source ❖ Different effects on the removal efficiency were appeared both in culture systems and among treatments, but the highest removal efficiency showed in TN (63 %-semi), TP (59%-flow), TSS (86%-flow) and COD (30%-flow) ❖ So, this species is an excellent candidate in connection with an integrated aquaculture for wastewater treatment and nutrient recycling

• New R&D Project :

Mass production techniques development for aquaculture industrialization of high-value polychaete and its application to coastal preservation

(2014. 10. 1 start)

1) Establishment of systematic technology on mass production of the rockworm polychaete Marphysa sanguinea 2) Construction of model system for introducing mass production techniques 3) Education, guidance and transfer of high production techniques 4) Environmental preservation by applications of polychaete-assisted aquaculture techniques
