ZAS IN A NUTSHELL (A TIMELINE OF INNOVATIONS)
Starting in Southern Brazil
Pioneered commercial freshwater shrimps in ponds and tilapias in cages production in South America.
100% Water Reuse
First to demonstrate water/feed balance of elements in aquaculture, creating the aquaculture concept of “Elements (macro/micro) Biomanipulation” that allows 100% of water reuse in Recirculation Aquaculture Systems (RAS).
Monosex Shrimp Culture
Participated in Dr. Amir Sagi’s group at HUJ on the first androgenic gland ablation trials for the aquaculture of freshwater prawns and marine shrimps, and later in 1993 with the Australian crayfish red-claw (University of Queensland).
Importation of tilapia stocks to Brazil
Demonstrated to Brazilian authorities the need to import tilapia genetic materials to improve the performance of inbred depleted stocks available during the 90’s.
First Brazilian Aquatic Feed line
Created the first Brazilian commercial line of aquatic feeds (AcquaLine) at Alisul Alimentos S.A. (Supra feed), totaling 12 poly-phase formulations for fishes and shrimps.
Improved Tilapias to Americas
Organized and lead the first importation process of genetically improved Tilapias (Chitralada Strain), from the Asian Institute of Technology (AIT, Thailand), generating thousands of Jobs and economic growth all over Americas in the coming decades; started the first tilapia Family Breeding Program in Americas, Veggie-Fish (currently 27th generation).
Artificial Incubation technique
Introduced in Americas the Artificial Incubation (AI) technique for tilapia egg production, resulting in hatcheries 12x more efficient compared to the previous scooping fry method, a key-factor for the initial success of Arabel, a company Sergio Zimmermann co-funded same year and named Aquabel later, that turned to be one of the largest in Brazil.
First Bioflocs in Brazil
Pioneered Bioflocs in Brazil, initially with tilapia and 5 years later with vannamei shrimps; development of the first commercial biofloc prototype for tilapia juvenile production in 2001 and vannamei shrimp in polyculture with tilapia in 2004.
The largest Tilapia hatcheries
From 2000 to 2003 designed/supervised constructions of the largest tilapia hatcheries in the World, ProGift (Haikou, China - 2000), Gifu-GenoMar (SangGiang, China - 2002), and Manit (Pechaburi, Thailand - 2003), being start-up supervisor and currently technical responsible for the later; those hatcheries produce together today more than 1 billion fries.
Breeding in Stable Environment
Pioneered Biofloc Technology in tilapia breeding (Veggie-Fish), quadrupling heritability values.
Zero Effluents in intensive ponds
First recirculation system for intensive earthen pond production in Mexico (AquaSur) and Thailand (Manit Farm); this simple revolutionary method of 100% water reuse is the base for recent commercial Biofloc/RAS and Aquamimicry systems for shrimps and tilapias.
Multi-species Breeding Program
Pioneer in the hybridization of four tilapia species in one breeding program (Veggie-Fish – with Oreochromis niloticus, O. andersonii, O. angolensis and O. mosambicus).
Circular Economy and Aquaponics
Circular Economy concept applied at Sun Aquaponics in Miami, Florida, a passion-fruit orchard drip-irrigated with water from a tilapia/paiche/shrimp production.
Applied the concept of Bioflocs and 100% recirculation with the nitrification/sediment compartment and microbe recovery using chicanes that started the recovery process of the company and the development of its AquaScience concept recently purchased by CP (Thailand).
Veggie-Fish (www.veggie-fish.com) became the second longest tilapia breeding program in continuous operation (since 1996) fully documented and (2019 on its 27th generation), considered by an Inocap report (Norway, 2014) as one of the main sources of tilapia genetics, with 5.8% of the global sector (400 million fry sold annually in Americas).
Fermented Partial Feed Substitute
Revolutionary development of FermentAqua, www.fermentaqua.com, the first commercial Premix that ferments when mixed with water and low-cost ingredientes, partially replacing expensive aquafeed; it is designed for any omnivorous species at all culture stages.
