Three weeks of conditioning on high nutrition feed prior to commercial production. The use of biosecure, disinfected wet or live feeds (polychaetes/squid/mollusks) is highly recommended.
General feeding regime guidelines as a percentage of total biomass in each maturation system tank:
- Squid: 5-8% per day
- Polychaete worms: 18-24% per day
- Other mollusks (clams/oysters, if desired): 4-7% per day
- Commercial semi-moist broodstock conditioning pellets: 3% per day (should be first feeding of day)
Feedings should be alternated throughout the day (4-6 times) and monitored to feed to satiation and avoid overfeeding. The excess feed should be removed prior to the next feeding, and adjustments made accordingly. The appetite of broodstock will change based on the molt cycle as well as the increase of nutritional demand during the onset of egg/sperm development.
If available, SPF certified feeds are recommended to mitigate possible infection by pathogens carried by wild polychaetes, mollusks, and squid. If certified SPF feeds are not available, then proper disinfection using a povidone-iodine solution at 20ppm concentration for 10-15 min followed by a thorough rinse in clean water is another option.
