“Essential non-essentials”: COVID-19 policy missteps in Nigeria rooted in persistent myths about African food supply chains
Type: Journal Article
Food supply chains are extremely important for food access and livelihoods across Africa, but their role is
often overlooked and underappreciated. Under normal conditions, the gap between myth and reality can result in the ...
Emerging COVID-19 impacts, responses, and lessons for building resilience in the seafood system
Type: Journal Article
The COVID-19 pandemic and subsequent lockdowns are creating health and economic crises that threaten food and nutrition security. The seafood sector provides important sources of nutrition and employment, especially in ...
Agonistic behaviour and feed efficiency in juvenile Nile tilapia Oreochromis niloticus
Type: Journal Article
The main hypothesis of the present study was that an aggressive and dominant fish would eat more feed and would be more efficient. To test this hypothesis, estimations of the relationships between agonistic behaviour, ...
Securing a just space for small-scale fisheries in the blue economy
Type: Journal Article
The vast development opportunities offered by the world’s coasts and oceans have attracted the attention of governments, private enterprises, philanthropic organizations and international conservation organizations. ...
Concentration and quantification of Tilapia tilapinevirus from water using a simple iron flocculation coupled with probe-based RT-qPCR
Type: Journal Article
Background: Tilapia tilapinevirus, also known as tilapia lake virus (TiLV), is a significant virus that is responsible for the die-off of farmed tilapia across the globe. The detection and quantification of the virus using ...
Rapid genotyping of tilapia lake virus (TiLV) using Nanopore sequencing
Type: Journal Article
Infectious diseases represent one of the major challenges to sustainable aquaculture production. Rapid, accurate diagnosis and genotyping of emerging pathogens during early-suspected disease cases is critical to facilitate ...
Different levels of probiotics affect growth, survival and body composition of Nile tilapia (Oreochromis niloticus) cultured in low input ponds
Type: Journal Article
A 7-month experiment was carried out to determine the effects of different levels of probiotics (baker's yeast (Saccharomyces cerevisiae) and Bacillus subtilis) on Nile tilapia (Oreochromis niloticus) reared in low input ...
Genome-wide association analysis of adaptation to oxygen stress in Nile tilapia (Oreochromis niloticus)
Type: Journal Article
Background: Tilapia is one of the most abundant species in aquaculture. Hypoxia is known to depress growth rate, but the genetic mechanism by which this occurs is unknown. In this study, two groups consisting of 3140 fish ...
Valuing small fish from mosquito nets: A comment on Jones & Unsworth (2019)
Type: Journal Article
A critique of a paper in Ambio that labels the capture of small fish as unsustainable without adequate consideration of the dynamics of fish populations.
A systematic literature review of the major factors causing yield gap by affecting growth, feed conversion ratio and survival in Nile tilapia (Oreochromis niloticus)
Type: Journal Article
Productivity among small‐ and medium‐scale tilapia farms varies considerably. The difference between the best performers and lower ones (yield gap), is affected by differences in growth rate and feed conversion ratio (FCR). ...
