“Safe Fish!” seminar attracted more than a hundred visitors – where internationally renowned speakers presented their view on sustainable aquaculture

The one-day seminar, under the umbrella of “Aquatic Asia at VIV” was held recently as part of the VIV at BITEC in Bangkok and hosted by leading companies in functional feed additives for aquaculture, ADDCON, Biorigin and Phytobiotics.

The event, under the theme “Safe Fish!” opened on the theme of consumer demand as a key driver of sustainable aquaculture with a presentation by Kurt Wegleitner, MD of ADDCON. He stressed the FAO Fish 2030 report’s findings that over the next 15 years, demand for fish will require that aquaculture production continues to grow at the expense of wild caught fish. Based on this growth, the amount of fish available overall, will have grown from 123 million tonnes in 2009, to 152 million tonnes by 2030 (Figure 1). Within this framework, he also stressed the effects of market requirements, especially the demand for sustainability within the aquaculture production chain.

Internationally-renowned independent experts gave the keynote lectures. Prof. Wing-Keong Ng from the Universiti Sains Malaysia explained comprehensively the use of functional feed additives in sustainable shrimp aquaculture, especially in the light of the challenges posed by emerging shrimp diseases, like EMS and the mis-use of antibiotics. In this regard, he highlighted research already done on the use of organic acids, β-glucans and phytogenics.
Dr. Tobias Steiner explained in more detail the use of such phytogenic feed additives in aquaculture.

Dr. Malou Cuvin-Aralar, from the SEAFDEC-AQD (Southeast Asian Fisheries Development Center – Aquaculture Department) in the Philippines, who also guided proceedings eloquently throughout the seminar, focused her talk on sustainable formulations in aqua diets. With the growth of demand for aquaculture products driving the industry towards intensification, it is even more necessary to produce nutritionally complete feeds sustainably, as laid out, for example in the Regional Guidelines for Responsible Aquaculture in SE Asia (Article 9.4.3). Feed additives, she explained, have a valuable role to play in the economic efficiency of feeds.
Taking the customer perspective, Dr. Prakan Chiarahkhongman, from CP Thailand, discussed the role of BAP (Best Aquaculture Practice) in producing safe, economically viable products for the market. Although there is no ‘silver bullet’, he discussed how feed additives, including β-glucans can, as part of a BAP system, help to manage healthy growth in fish and shrimp.
In order to achieve healthy growth in fish and shrimp, it is essential to supply them with safe feed. Eng. D. Bulanhagui, an independent consultant from the Philippines, explained in detail the production techniques for safe feed for fish and shrimp. He explained in detail, the crucial relationship between temperature and humidity, based on the psychrometric chart. This physical relation can be used to predict the probable outcomes of feed pelleting and storage, relative to the potential danger of microbial contamination. Under SE Asian conditions, this is especially relevant.
Finally, Dr. Christian Lückstädt, the newly appointed Technical Director of ADDCON, brought his experience with the use of dietary acidifiers in tropical aquaculture to the question of producing safe feeds for healthy fish and shrimp production. In times of high raw material prices, especially protein sources, the use of such additives may become more relevant, since it has been demonstrated by many researchers that the use of dietary organic acids and their salts improve protein digestibility in various aquaculture species.

The seminar closed with a podium discussion and a reception held under the auspices of Aquatic Asia. 

For interested readers, the presentations of all speakers are available for download from ADDCON.
