In this thesis we focus on dynamics of mussel beds and the impact and effectiveness of culture activities on mussel production yield. The theoretical framework of this thesis is introduced in Chapter 1 and the major objectives are stated as: (1) to better understand the population dynamics of...

The general objective of this thesis is to investigate the interactions between existing state and non-state actors and institutions governing the shrimp industry to develop a more informed understanding of how the state, market and community-based governance arrangements at different levels...

The farming of Pacific white shrimp Litopennaeus vannamei in northeast Brazil, has proven to be a promising sector. However, the farming of Pacific white shrimp in Brazil has been affected negatively by the occurrence of viral diseases, threatening this sector's expansion and sustainability. For...

White spot syndrome virus (WSSV), the causative agent of white spot disease (WSD), has been responsible for most shrimp production losses around the world since the early 1990s. Previous research has focused mainly on the characterization of WSSV genomic variation to gain a better insight in the...

Bacteria of the family Vibrionaceae are ubiquitous in aquatic habitats. The genus Vibrio includes species that are pathogenic for humans or fish. The incidence of human infections and in aquaculture has been increased and is, to some extent, associated with the emergence of new pandemic strains....

Three technologies showed to improve productivity and sustainability of pond production: (1) C/N ratio control of feed inputs, (2) providing substrates for periphyton development, and (3) fish driven re-suspension. The novelty of this PhD research is to combine these technologies, with the goal to...

There has been a steady increase of literature discussing the environmental impact of the large and economically important shrimp farming industry worldwide, including pollution of surrounding waters, destruction of mangrove forests and depletion of natural resources. However, the literature is...

More than a decade after its discovery in South-East Asia, White Spot Syndrome Virus (WSSV) is still the most important (viral) pathogen in the shrimp culture industry. Despite the shift from culturing Penaeus monodon towards the presumed less susceptible Litopenaeus vannamei, the use of specific...

This thesis describes the integrated nursery subproject, wherein the rearing of fingerlings of sole is combined with the cultivation of microalgae as feed for shellfish larvae and spat inside a greenhouse. A horizontal tubular photobioreactors is designed and constructed to investigate the...

This study (thesis) focused on improving production and benefits from polyculture of tilapia O. niloticus and freshwater prawn M. rosenbergii by small-scale farmers in Bangladesh. Stocking low densities of prawns in fish (tilapia) ponds resulted in a small additional yield of prawns but also...
