The novel coronavirus is predicted to have dire implications on global food systems including fisheries value chains due restrictions imposed human movements in many countries. In Ghana, production, both agriculture and fisheries, exempted from as an essential service. enforcement of COVID-19 prevention protocols, particularly social distancing, has been widely reported Ghana's agricultural markets whereas casual observations media reports fish landing sites suggest no such enforcements are...
The fiscal and social cost of ameliorating the impact coastal erosion resulting from climate change is an increasing burden for states, in developing nations physical interventions implemented may present a double agony - debt levels potentially obstructing livelihoods rural coasts. Against this background, study was conducted to explore hard-engineered protection on vulnerability community Ghana using combination Unmanned Aerial Vehicles (UAV), geographic information system tools survey....
Abstract This paper presents an agenda for the future of gender research in small‐scale fisheries (SSF). Building on expert insight from scholars who gathered during 4th World Small‐Scale Fisheries Congress Africa (4WSFC) with a synthesis existing literature, we identify six topics that warrant investigation SSF, along methodological considerations addressing them. Research priorities include identifying pathways towards (1) equitable participation governance and decision‐making, (2) valuing...
The West African mangrove oyster, Crassostrea tulipa (Lamarck, 1819), has the potential to improve global shellfish food production and is being considered for commercial farming in many countries Africa. current background information support this venture is, however, inadequate. We assessed effectiveness of five substrates (coconut shell, oyster nylon mesh, PVC, ceramic tile) harvesting C. spat from Densu Delta, Narkwa Lagoon, Benya Lagoon Whin Estuary, along coast Ghana November 2017...
Globally, over 85% of oyster reefs have been lost, and the combined effects climate change, ocean acidification, environmental degradation, including pollution mangrove overharvesting, could further reduce global fisheries in coming decades. To understand level impact change on fishery West Africa, an expert-based vulnerability assessment to was conducted for African (Crassostrea tulipa, Lamarck 1819). Using a combination exposure climatic stressors (estuarine temperature, salinity, river...
The governance of coastal and marine resources remains a complex socio-ecological endeavor in many African countries, but women are leading the way demonstrating pathway for food fish security through rights-based co-management shellfisheries estuarine mangrove ecosystems West Africa. We report comprehensively, first time, scale ecosystem-based across coast (Senegal, Gambia, Guinea Bissau, Guinea, Sierra Leone, Liberia, Côte d’Ivoire, Ghana, Togo, Benin, Nigeria), gender dynamics,...
Uncertainties associated with wild harvests of seed and adult oysters due to unknown oceanographic oscillations are a major challenge in oyster fisheries aquaculture development. In contribution addressing this challenge, we proffer clarity on the spatiotemporal variations spatfall (number spat/m 2 ) mangrove Crassostrea tulipa (Lamarck, 1819) four estuaries along Gulf Guinea coast. By monthly deployment artificial substrates affixed bamboo racks over 12 months, find significant differences...
The Pacific oyster is prominent in global food security and the blue economy. As an unfed aquaculture species, offers substantial potential to contribute United Nations Sustainable Development Goals related hunger, health, employment. By capitalising on its biophysical attributes, industry can enhance production efficiency economic sustainability. This study advances critical insights into commercially important traits of across supply chains southern Australia (South Tasmania). Applying...

Abstract Microplastic ingestion by marine organisms presents a challenge to both ecosystem functioning and human health. We characterized microplastic abundance, shape, size, polymer types ingested the West African mangrove oyster, Crassostrea tulipa (Lamarck, 1819) sampled from estuaries lagoons Gambia, Sierra Leone, Ghana, Benin, Nigeria using optical microscopy Fourier transform infrared (FTIR) techniques. A total of 780 microplastics were isolated in whole tissues 250 oysters ( n = 50...
The ability to accurately estimate the length of rope needed in construction stringed cultch masses for farming oysters without wastage is a major practical challenge. problem arises mainly due illusive ghost length subsumed by knotting cultches on strings which potentially has dire financial implications oyster farmers. Using repeated measures diameter (D) and thickness (T), we derived regression models estimating further deduced an equation determining appropriate total (L) stringing...
Abstract The West African mangrove oyster, Crassostrea tulipa (Lamarck, 1819), has the potential to improve global shellfish food production and is being considered for commercial farming in many countries Africa. current background information support this venture is, however, inadequate especially with respect identification of suitable materials optimal collection spat large-scale production. We assessed effectiveness five locally available (coconut shell, oyster nylon mesh, PVC, ceramic...
