7 Hatchery techniques have been well-established

8 Hatchery techniques have been well-established Amenable to rearing at high densities

9 Hatchery techniques have been well-established Amenable to rearing at high densities Easy to see and catch

10 Hatchery techniques have been well-established Amenable to rearing at high densities Easy to see and catch Amenable to artificial feeding

11 Hatchery techniques have been well-established Amenable to rearing at high densities Easy to see and catch Amenable to artificial feeding Appropriate nutritional requirements Ideally, the species eats low on the food chain

12 Hatchery techniques have been well-established Amenable to rearing at high densities Easy to see and catch Amenable to artificial feeding Appropriate nutritional requirements Ideally, the species eats low on the food chain Rapid growth with little population variation

13 Hatchery techniques have been well-established Amenable to rearing at high densities Easy to see and catch Amenable to artificial feeding Appropriate nutritional requirements Ideally, the species eats low on the food chain Rapid growth with little population variation Efficient food conversion

14 Hatchery techniques have been well-established Amenable to rearing at high densities Easy to see and catch Amenable to artificial feeding Appropriate nutritional requirements Ideally, the species eats low on the food chain Rapid growth with little population variation Efficient food conversion Non-cannibalistic

15 Hatchery techniques have been well-established Amenable to rearing at high densities Easy to see and catch Amenable to artificial feeding Appropriate nutritional requirements Ideally, the species eats low on the food chain Rapid growth with little population variation Efficient food conversion Non-cannibalistic Disease resistant

16 Hatchery techniques have been well-established Amenable to rearing at high densities Easy to see and catch Amenable to artificial feeding Appropriate nutritional requirements Ideally, the species eats low on the food chain Rapid growth with little population variation Efficient food conversion Non-cannibalistic Disease resistant Hardiness

17 Hatchery techniques have been well-established Amenable to rearing at high densities Easy to see and catch Amenable to artificial feeding Appropriate nutritional requirements Ideally, the species eats low on the food chain Rapid growth with little population variation Efficient food conversion Non-cannibalistic Disease resistant Hardiness Good fillet yield / High meat recovery

18 Hatchery techniques have been well-established Amenable to rearing at high densities Easy to see and catch Amenable to artificial feeding Appropriate nutritional requirements Ideally, the species eats low on the food chain Rapid growth with little population variation Efficient food conversion Non-cannibalistic Disease resistant Hardiness Good fillet yield / High meat recovery Marketability

19 Hatchery techniques have been well-established Amenable to rearing at high densities Easy to see and catch Amenable to artificial feeding Appropriate nutritional requirements Ideally, the species eats low on the food chain Rapid growth with little population variation Efficient food conversion Non-cannibalistic Disease resistant Hardiness Good fillet yield / High meat recovery Marketability Consistent and reliable supply of eggs and / or fry

20 Paradigm for Broodstock Development What are the impacts to productivity, economics and sustainability? Genotype What is the genetic basis of variation in the desired trait? Identify and select for natural variation in desired traits to Performance improve productivity, Physiology economics, and sustainability. Can the response be altered or detected to increase performance? Behaviour How does the trait perform in different environments and why?
