Bioturbation activity generated by fish has the potential to improve bottom soil quality by increasing oxygen supply to a greater depth in aquaculture ponds bottoms. This study was designed to assess the common carp ( Cyprinus carpio L) potential to

A large amount of feed and other organic material is found as suspended matter in super intensive fish production tanks. Both treatment and recycling of these organic materials depend on the size and stability of the particles in suspension. The stab

Soil pH is a key factor in several chemical processes occurring in the pond bottom environment. Conventionally, pH determinations are made on 1:1 dry soil:distilled water paste (pH 1:1 ). However, such pH data might not be relevant for flooded soil c

Several basic properties of pond bottom soil are shown to be related, a relation that enable to evaluate pond bottom soil characteristics through the determination of one parameter (e.g. soil moisture). In addition, these relationships give some insi

Compost was prepared from the organic fraction of the municipal solid waste stream, using a windrow process. Stability was defined using rather simple tests. The pH was acidic at the beginning and stabilized near a neutral range. Electrical conductiv

Water quality in intensive aquaculture systems is to a large extent controlled by the microbial biodegradation of organic residues. The ability to simulate processes in such systems depends on the availability of data on the rates of these processes.

A model describing the nitrogen sub-system in a completely mixed and aerated pond is proposed. Inputs of nitrogen include feed and influent water; outputs of nitrogen include uptake by fish, removal of sediment from the pond and discharge water. Inte

Individual granules within a given granule population of a slow-release fertilizer (SRF) have a different release pattern. The populations studied differed both in relation to the time delay before the start of the release process and to the duration
