Received his Ph.D. in Engineering in Aquaculture, Universidad de los Lagos, Osorno, Chile in 1985. Dr. Catalan was also granted his Diploma in Business Administration from the Universidad Austral de Chile in 1994. He is currently the Production Manager of Prosmolt SA. Prosmolt produces 7.5 million smolts per year including 4.5 million all-female smolts. Dr. Catalan pioneered the use of all-female production in Chile.

Abstract of Dr. Catalan's presentation

Production statistics for species of salmon raised in Chile are presented. All-female production techniques are discussed with particular reference to techniques and culture performance. All-female salmon perform with the same level of growth characteristics in the hatchery and in early seawater grow-out. However, mean harvest weight of salmon is delayed by about one month. Despite this, the gains made by decreasing grilse rate offset this delay.

Received his Bachelors of Aquaculture Engineering, Universidad de los Lagos, Osorno, Chile in 1981. and his Diploma in Business Administration from the Universidad Austral de Chile in 1995. Mr. Miranda is the Technical Manager for Salmones Pacifico Sur S.A. and is the former Technical and Broodstock Manager for Marine Harvest Chile. While in this former position, he pioneered the use of all-female stocks. Mr. Miranda is an expert in using selective breeding programmes in production situations to increase stock performance.

Abstract of Mr. Miranda's presentation

Selective breeding programs have immediate and long-term benefits to producers. Gains of 10-25% can be made in areas of growth, pigmentation, FCR, fat deposition and colour within one generation. Production-based breeding programmes augment production fish with family groups that have been selection with only a one generation lag time, but the most favoured effects are noticed in six years. All-female programmes benefit from selective breeding programmes in that losses in time to harvest can be recouped if not surpassed.
