Seaweeds for feed and food production

The protein challenge

World population 2050: +33%

Global meat consumption 2030: +50%

3-6 kg plant protein required for 1 kg meat protein

Urgent need for an increase in plant protein production

Page 4: Jacques Neeteson, Manager, Agrosystems Research

Protein sources for animal production

Current global need for feed protein: 1 billion tonnes per year

Major current source: soybean

Page 5: Jacques Neeteson, Manager, Agrosystems Research

Protein sources for animal production

Extension of soybean production?

● Greater demand of land and fresh water

● Loss of biodiversity

● Further distorted nutrient balance

Alternative protein source: seaweed

● Use of seas and oceans

● No fresh water required

Page 6: Jacques Neeteson, Manager, Agrosystems Research

Brown seaweeds 2.000 species

Green seaweeds 1.200 species

Red seaweeds 6.000 species

Test location The Wierderij

Crop cultivation of seaweed

Page 12: Jacques Neeteson, Manager, Agrosystems Research
Page 13: Jacques Neeteson, Manager, Agrosystems Research

First-year seaweed production at The Wierderij

Year-round production: the combination of green and brown seaweeds yielded 25,000 kg dry weight/ha.

Prospects for seaweed cultivation

in the Middle East

Gracilaria multipartita

Eucheuma cottonii

Ulva lactuca

Page 15: Jacques Neeteson, Manager, Agrosystems Research

Gracilaria

multipartita

Productive in tropical seas such as the Red Sea and the Arabian Gulf

Production system is not yet optimised

Page 16: Jacques Neeteson, Manager, Agrosystems Research

Eucheuma

cottonii

Productive, but susceptible to diseases

Production system is not yet optimised

Page 17: Jacques Neeteson, Manager, Agrosystems Research

Ulva lactuca

Grows well in warm sea water

25% of DW is high value protein

Production system is not yet optimised

Prospects for seaweed cultivation

in the Middle East

Gracilaria multipartita

Eucheuma cottonii

Ulva lactuca

Gracilaria, Eucheuma and Ulva cultivated in an integrated year-round

system may be a sustainable production system

Profitability of seaweed cultivation

Benefits (AED per ha) Carbohydrates 50,000 Proteins-food (20%) 25,000 Proteins-feed (80%) 15,000 PUFAs 6,250

Total 96,250

Annual yield of 25,000 kg dry weight per ha 10,000 kg carbohydrates 5,000 kg proteins 625 kg PUFAs

Page 20: Jacques Neeteson, Manager, Agrosystems Research

R&D challenges

Production of propagation material

Construction of robust, but flexible, production facilities

Development of site-specific sustainable production systems

Development of efficient harvesting technology

Development of cost-efficient upstream production chains
