1 The CreveTope production system is based on studies by CreveTec at ILVO (Oostende, Belgium), and the research station of Aquaculture Farming Technology (Venray, Netherlands) 1. Introduction CreveTope shrimp farm system is the most promising new method for environment friendly closed shrimp farm production system in the world, in this system you can farm shrimp in high densities in smaller surroundings with year round production! CreveTope the ultra-intensive culture of shrimps without the use of new water through a biological treatment of aerobic and heterotrophic, also called biofloc technology. Once established it brings down the production costs with 20 % and lowers the Feed conversion ratio! Thanks to zero exchange of water with no effluents the environmental impact is reduced. The application of such a system meets the growing aquaculture concept of a responsible, sustainable and environmentally shrimp farming method. The CreveTope system also reduces the risk of introduction and spread of diseases. When covered with a building or greenhouse this system provides the only good option for a bio-secure shrimp farm. The CreveTope module is equipped with an advanced bioreactor, which increases the flexibility of water quality management. Addition of chemicals for ph adjustment is not necessary and nitrate levels are controlled. Excess bioflocs can be removed without special equipment. The advanced utilisation and control of bioflocs not only reduces the environmental impact, but also enables nutrient recycling into new protein biomass, as additional nutrition for the shrimp, resulting in faster growth and reduced FCR. This will also give the farmer outside the EU greater access to markets with stringent safety standards. We are specialized in these systems and can help you with design and constructing of these systems. Thanks to the re-use of water, our system can be build anywhere in the world, in the tropics, in temperate climates, in the desert, close to towns, in buildings, former pig and chicken sheds and in greenhouses. Our system is easy to handle and manage and has low operational costs.

2 2. Advantages Higher shrimp per m 3 volume water Location and climate independent Whole year climate independent production Lower feed conversion ratio Higher bio-security Higher survival rate Zero water exchange Possiblity of partial harvests enables sales of fresh shrimp for local market More crops per year Whole year locally produced fresh shrimp System is suitable for L. vannamei and P. monodon 3.
