The 5th Annual Aqua Feed Extrusion Conference co-organized by VIV, International Aquafeed and Fish Farming Technology magazine and Dr Mian Riaz of Texas A&M University is once again taking place on 10-11 March, 2021. The full programme has now been released:

Day 1

First day of the 5th Annual Aquafeed Extrusion conference will focus on selection of an appropriate extruder for aqua feed, modern aquatic plant design, preparation of raw material for aqua feed using pulverizer, making floating and sinking feed using twin screw extrusion technology and optimization of aqua feed quality. 

Selection of an Extruder
As we know, in today's market, several companies offer all kind of extruders for making aqua feed, which can make the process of selecting an appropriate extruder very confusing for the consumer. There are too many choices in the market for buying an extruder.

Modern aquatic plant design
Extrusion projects are not an easy task to undertake. Whether you are building a new factory or expanding your operation, proper planning is key to the success of a completed project.

Preparation of the raw Material
First step in making aqua feed is to prepare your raw material using proper grinder and pulverizer for extrusion and that can be very costly, if not careful, you can spend lot of energy and efforts and then still ended up with poor quality pellets.

Making Floating and Sinking Feed with Twin Screw Extruder
Currently we have choices to use single or twin-screw extruder to make aquafeed, and twin-screw extrusion provide more flexibility and choice to make different sizes of pellet and it allows to make floating or sinking feed as well.

Optimization of Aquafeed Quality
Once feed is made; we need to make sure its quality. Final aqua feed and majority of raw materials used for their production, due to their substantial level of total fat and high ration of polyunsaturated fatty acids are very sensitive to oxidation process. Oxidation of feeds can negatively impact economy of feed producers, since primarily will impact feed quality with consequent possible increase of customers complain and/or feed re-call. Moreover, oxidation can have a direct effect on fish performances and state of health. Thus, a good knowledge of oxidation process and way to prevent/control via the application of a specific antioxidant program, remain a must for producing high feed quality.

Day 2

The second day of the conference will focus on Twin screw extrusion of aqua feed, Evolution of extrusion technology, Common Aquafeed drying challenges, Sustainable and nutritious fish feed pellets with twin screw and Proposition for enzymes in extruded feed.

Twin Screw Extrusion of Aqua Feed
As the recent changes in raw material demand and availability, the extrusion of 'new' raw materials for dry fish feed and pet food products has challenged the traditional way of producing quality products from premium raw materials. To accommodate this challenge the development and use of twin-screw technology has become more intense and, in some region, market like in Asia, starting to become the most preferred technology in especially fish feed extrusion.

Evolution of Extrusion Technology
Extrusion processing has been used for many years for products that countless people use daily.  Family pets, livestock, and aquaculture are all examples of who/what extrusion proves to be a valuable and flexible processing aid.  From producing the most basic of feeds to complex, high quality formulations, aquatic feeds have evolved through the years, therefore it is necessary to expect the same for extrusion technology.

Common Aquafeed Drying Challenge
Every Aquafeed manufacturer faces operational challenges from time to time when producing high quality feed at maximum throughput and energy efficiency. Understanding the underlying cause of the problems faced during operation is a critical step in defining practical solutions to ensure reliable, high quality, efficient aquafeed production.

Sustainable and Nutritious Fish Feed Pellets with Twin Screw
Since protein-containing raw materials play an important role in achieving the most efficient growth possible, fish meal as a source of protein is a frequently used in the formulation to produce fish feed. However, this has led to an additional demand for fish resulting in a significant increase on the price of fishmeal. Consequently, efforts are being made to find alternative sources of protein to replace fishmeal, at least partially. A promising and more sustainable approach is the usage of insects as an alternative to fishmeal, since they can also be rich in protein and already serve as food for many fish in nature.

Proposition for Enzymes in Extruded Feed
The volatility in supply, price and quality of common protein sources used in aquafeed has prompted the use of dietary enzymes including protease by nutritionists and formulators worldwide. However, poor stability of any enzymes during the harsh manufacturing process of extruded aquafeed may have hindered their use and prompted several solutions such as coated enzymes or liquid enzymes for post-pelleting application. Here, we shall discuss the advantages and disadvantages of various such solutions proposed for dietary protease by reviewing peer-reviewed published literatures available in the scientific domains.
