Senior Thai Official to Open Strongly Technical Conference

Dr. Juadee Pongmaneerat, senior expert in fishery product and inspection, Thai Department of Fisheries, to open strongly technical aquafeed conference

Cultivated marine shrimp have been an important source of protein in Thailand for many years and the country has been an exporter since 1991.

In 2005 and 2006 total production of marine shrimp was about 380,000 tons and 410,000 tons respectively, and in 2007, that figure is expected to reach over 500,000 tons. However, the Thailand has not escaped the devastating disease outbreaks suffered in shrimp farms world wide: WSSV, TSV and IHHNV have taken their toll.

This and the uncertainty of healthy brood stock supply, has seen the country make a dramatic shift from black tiger shrimp (P.Monodon) to the white shrimp (P. vannamei) , which today accounts for 95-98 per cent of production.
Other major aquacultured species in Thailand are sea bass, grouper, green muscle, blood clam, oyster, tilapia, catfish and giant fresh water prawn. There are 155 registered aquafeed mills in the country including premixed, supplemental feed, concentrate feed and complete feed.

Dr. Juadee Pongmaneerat, senior expert in fishery product and inspection, Department of Fisheries, Bangkok, Thailand will open the Aquafeed Horizons Asia Conference with an update of the country’s aquaculture and aquafeed status and explain the steps the Department of Fisheries has established to develop a strategy and policy for sustainable aquaculture and to enhance the safety and quality of aquatic food.

The conference will have a strong technical emphasis. Delegates will discover the very latest innovations in feed additives, such as pheromone attractants and palatability enhancers. Ingredients to add to the aquafeed formulator’s arsenal will be presented - from krill to insects, and novel feed supplements and neutraceuticals to promote performance and health in farmed fish and shrimp.

Many of these new ingredients will have an impact on the processing and this will be examined as part of the afternoon session, which will be devoted to practical processing issues.

Can you use an extruder to make shrimp feeds?
Current technology and the advantages of this method of production will be reviewed in a talk that will cover all aspects of this process from the raw materials through to drying and cooling before packaging. Final product quality aspects will also be presented.

Starter feed production will be reviewed in another talk and the day will finish with a discussion of upstream processing to improve process efficiencies. It will explore work done on early pre-hydration and the effect on improved production rates, the hydration being either/and combinations of grain tempering and last minute addition of water to ground powders before going into the storage bin that feeds the extruder. This talk will also discuss high speed continuous mixer/choppers to hydrate and add other liquids before the conditioner, and the theory that supports these technologies.

Ways of misting steam and water into existing conditioners and the beneficial effect of these: the presentation will be an overview of techniques that are available to improve product quality through homogenous mixing and heating and to improve production rates and reduce machine wear.

As an end to the day, delegates will be able to sit back and enjoy a presentation on the very latest in contained aquaculture productions systems and the development of entoprotein – an alternative protein source from insects, about to be commercialized.

Aquafeed Horizons Asia announces hotel deals and joint registration with feed ingredient conference

Delegates to Aquafeed Horizons Asia 2008, which will take place at the Queen Sirikit National Convention Center, Bangkok, March 6, 2008, can now register jointly for the Feed Ingredients & Additives Asia Pacific (FIAAP) Conference. This related conference will take place at the same venue on the previous day.

"We know that many people will be interested in both conferences and it makes sense to register for both at once", Suzi Fraser Dominy, president of Aquafeed.com and both meetings, commented. "Combined registration will cut down the paper work for delegates ad save them money".

The FIAAP Conference program is close to being finalized and includes a number of presentations of direct relevance to the aquafeed community. In particular:
Natural Ingredients – Product Opportunities and Process Issues - Colin Mair, Cormal Technology Ltd., U.K.

Amino acid content in fishmeal shows high variation - Torben Gosvig Madsen, Regional Technical Service Manager, Degussa (SEA) Pte. Ltd.

A comparison of digestible protein and amino acids content and value of terrestrial animal protein meals for aquafeeds - Dr. Yu Yu, National Renderers Association, Inc.,

A healthy gut for optimal performance through target release concepts in animal diets - Koen Schwarzer, NUTRI-AD International N.V.

Bacterial Contamination Of Feed And Feed Ingredients – Importance Of Control For Food Safety And Animal Performance - Dr Adam Smith, Anitox Ltd, Earls Barton, Northants, NN6 OHJ, United Kingdom

Mycotoxins in animal nutrition - problems and solutions - Mathieu Cortyl, Impextraco NV, Singapore Representative Office.

Aqafeed Horizons sia and FAAP are beng held in association with Victam Asia 2008 and delegates will be ble to visit both shows freeof charge. Special hotel rates have been announced and you can find these on the conferences' websitebelow:
