2019-2020
Kingfish fingerling production
Objective: Demonstrate capabilities for year-round commercial-scale production high-quality kingfish juveniles for commercial and research use. To determine the impacts of various rearing strategies and environmental factors on the performance of kingfish fingerlings to optimise commercial farm design and operation.
Kingfish broodstock husbandry
Objective: Maintain and enhance our existing and kingfish broodstock performance.
Kingfish juvenile rearing
Objective: Optimise the performance of the stock through better rearing condition and genetic selection to directly support consolidation of the commercialisation readiness of the species.
Kingfish juvenile RAS optimisation
Objective: Test and develop technologies that improve the performance of kingfish in RAS, and the performance of the RAS itself.
Aquaculture discharge treatment
Objective: Develop techniques to improve aquaculture waste water treatment through minimisation of nutrient discharge and conversion.
Hapūku broodstock husbandry
Objective: Maintain a limited number of wild caught broodstock. Grow current spawning age F1 broodstock to reach an average weight of 18Kg body mass for females as fast as possible while minimising adiposity. Discourage spawning using temperature manipulation.
2018-2019

Kingfish RAS technology
Objective: Determine operational parameters for water quality in an intensive RAS for yellowtail kingfish.
Hapūku broodstock husbandry
Objective: Establish consistent commercial level production of juveniles through optimised broodstock husbandry to support commercialisation of the species.
Hāpuku juvenile production commercialisation readiness
Objective: Establish consistent commercial level of juvenile production and optimise cost-effective growout rearing practices to demonstrate commercial readiness of the species.

Objective: Develop and validate a health panel for kingfish based on haematology, mucous smear, behavioural assayswater chemistry, endocrine andimmunity markers, transcriptomics.
Marine finfish RAS development
Objective: Develop, refine and test both new and existing RAS technologiesfor the commercial on growing of Kingfish in order to optimise RAS design and operation.
Hāpuku broodstock husbandry
Objective: Maintain optimal husbandry conditions to sustain and improve egg and larvae quality, and assess capacity to influence breeding schedule through multi-year photothermal manipulation.
Hāpuku juvenile bottleneck
Objective: Demonstratethe following: a) viable egg production of >45% and >20% for F1 and F2 eggs, b)post-weaning survival of > 2%,and c) >30% juvenile survival.

Kingfish trials
Objective: Determine the impacts of various rearing strategies and water quality on the performance of kingfish in order to optimise RAS design and operation.
Hapūku broodstock husbandry
Objective: Assess the effects of feeding, environment, photothermal regime, and newly captured wild fish on the production of viable hāpuku embryos and larvae.
Hāpuku – Resolving juvenile bottlenecks
Objective: Identify key husbandry parameters that enable repeatable production of good quality hāpuku larvae and juveniles.
