As the number of inhabitants in Sub-Saharan Africa (SSA) increases, demand for animal-source proteins outstrips the current supply. Aquaculture is promoted to sustain livelihood and for improved food security. However, the production in SSA is still low at less than 1% of the total global production. Poor water quality is cited to be one of the fac...
An increasing global population has meant aquaculture, one of the fastest growing food industry sectors, faces significant sustainability challenges as it tries to address the rising global protein demand. In many sectors, production is underpinned by fishmeal as dietary ingredient, but this is a finite resource with competing users from the poultr...
This study aimed to evaluate the effects of four potential microbial strains, consisting of Candida parapsilosis, Pseudoalteromonas flavipulchra, Lactobacillus sakei, and Bacillus natto, on the suppression of Vibrio and the increase of population growth and enzyme activity in the copepod Tigriopus japonicus. Five treatments were set up, including f...

We pre-grew shrimp under polyculture (shrimp-tilapia 'ST' and shrimp-mullet 'SM') and monoculture (P-control) conditions until they reached the size of 10-12 g. Then, the shrimps were collected and injected with Vibrio alginolyticus (2.1 x 10(5) CFU shrimp(-1)). Some shrimp, originating from the shrimp monoculture, was also injected with sterile sa...
Yeast cells can play a crucial role in immune activation in fish and shellfish predominantly due to the cell wall component 13-1,3-glucan, providing protection against bacterial or viral infections. However, the immunostimulatory capacity of dietary yeast cells remains poorly studied in bivalves. To understand the role of yeast cell wall components...
Multiple ocean sectors compete for space and resources, creating conflicts but also opportunities to plan for synergistic outcomes that benefit multiple sectors. Planning and management are increasingly informed by qualitative and quantitative methods for assessing multi-sector interactions to identify trade-offs and synergies among sectors and wit...
Flavobacterium columnare, the causative agent of columnaris disease in a large variety of freshwater fish, is a major problem in commercial aquaculture. A limited number of antimicrobial therapies are available to control this disease; therefore, these agents must be used judiciously. To facilitate effective monitoring for changes in susceptibility...

Increasing efforts are directed towards the development of sustainable alternative protein sources among which microbial protein (MP) is one of the most promising. Especially when waste streams are used as substrates, the case for MP could become environmentally favorable. The risks of using organic waste streams for MP production–the presence of p...

BackgroundIntensive aquaculture farming has caused significant degradation of coastal wetlands and has been proposed as a reservoir for pathogenic Vibrio spp.ResultsGut pathogens including Vibrio spp., Salmonella spp., and Klebsiella spp. were isolated from bird feces, shrimp and wetland water in two typical coastal regions of China in 2015 and 201...
