“…Interestingly, findings from a quantitative study suggested that the Lake has a fairly good chemical health status (Tay, 2021). However, the results from a qualitative study corroborate the findings in this study, as water quality was purported to have aggravated disease incidences in farmed fish on the Lake (Abarike et al, 2022). The results in this study thus suggest the need to formulate testable hypothesis on specific water quality contaminants, such as herbicides and pesticides, as disclosed by the participants.…”

Unusual fish mortalities in aquaculture threaten global food security and carry significant socio-economic burdens. In 2018, Nile tilapia (Oreochromis niloticus) suffered unusual patterns of mortalities, attributed to disease-causing agents in Lake Volta cage aquaculture. In recent times, disease investigations have shifted from single to consideration of multiple factors to understand the puzzling range of causal risk factors. This study therefore aimed at expanding on tilapia mortality risk factors, while documenting fish health and Lake Volta management practices for sustainable aquaculture. We interviewed relevant aquaculture stakeholders operating on Lake Volta and conducted thematic analysis on their responses to map out mortality risk factors and management practices. The identified risk factors were conceptualized in established models of causation web and Social-Ecological System to explain the practical significance of the findings. The results showed that the risk factors of tilapia mortalities are a combination of pathogens and non-infectious factors mediated by weak law enforcement. The results further suggested mortality reinforcing mechanisms through the horizontal transmission of pathogens, namely, Streptococcus agalactiae and Infectious Spleen and Kidney Necrosis Virus. Moreover, the recognition of weak enforcement as a possible factor reinforcing human activities is a non-infectious route that can be deleterious to fish health. Health management practices comprised phytotherapy, vaccination, heat shock treatment, biological controls, and best husbandry practices. Lake management involves creating a waterfront buffer of 85.34 m, surveillance, and executing the framework guiding aquaculture development on the Lake. The findings are suggestive of complementary quantitative studies that augment the qualitative evidence herein. Such follow up studies can disclose precise mortality risk factors to inform policy directives and effective remedial strategies that can secure fish and lake health.

“…Sampled cage farms in stratum II of the Volta Lake within the Akosombo Dam at 6°17′57.7″ N 0°03′19.6″ E is designated as upstream, through the area between the Akosombo Dam and Kpong Dam at 6°07′12.4″ N 0°07′31.4″ E is designated as midstream, and after the Kpong Dam at 6°06′02.3″ N 0°09′26.2″ E through to the Akuse area is designated as downstream. These demarcations are the original sections of the stratum II of the Volta Lake, which were the sampled areas for the study (Figure 12) [64].…”

Background: Antibiotic residue in food products and the resulting antibiotic-resistant bacteria represent a significant global public health threat. The misuse of antibiotics is a primary contributor to this issue. This study investigated the knowledge, attitudes, and practices (KAP) regarding antibiotic use among cage fish farmers on Ghana’s Volta Lake. Method: We conducted a cross-sectional survey with 91 cage fish farmers across three scales: small, medium, and large. A semi-structured questionnaire complemented by personal observations provided comprehensive data. We used several statistical methods for analysis: Pearson Chi-Square and Spearman correlation tests to examine relationships and trends among variables, logistic regression to analyze variable interactions, and Cronbach’s alpha to check internal consistency. Additionally, Kendall’s coefficient was used to rank challenges, utilizing STATA and SPSS for these calculations. Results: The survey revealed that 58.55% of cage fish farmers earn an average of 10,000 USD annually, with 35.16% having over 16 years of experience. From the survey, all sampled populations admitted to antibiotic applications in their farming operation. Knowledge of antibiotic types was mainly influenced by peers (46.15%), with tetracycline being the most recognized and used. There was a significant reliance on the empirical use of antibiotics, with 52.75% of farmers using them based on personal experience and 40.66% without a prescription. When initial treatments failed, 41.76% of the farmers would change or combine drugs. Older farmers (over 51 years) and those with tertiary education demonstrated significantly better KAP scores regarding antibiotic use. Strong correlations were also found among knowledge, attitudes, and practices in antibiotic usage. Conclusions: The findings indicate a need for improved education on antibiotic use among fish farmers to reduce misuse and enhance awareness of the potential consequences. This study provides foundational data for designing interventions to address these issues in the context of cage fish farming on Volta Lake.

Deniz ürünleri üretimi, milyonlarca insana istihdam ve geçim sağlayan kritik bir küresel endüstridir. Sektördeki üretim teknolojilerinin yoğunlaşması, deniz ürünleri üretimindeki arz-talep açığını kapatmak için ortaya çıkmıştır, ancak potansiyel halk sağlığı tehditlerine ilişkin endişeler gündeme gelmiştir. Örneğin, su ürünleri yetiştiriciliği ortamlarında artan stok yoğunlukları balıklarda stresin artmasına yol açarak patojen çoğalmasına elverişli bir ortam yaratmıştır. Antibiyotikler balıklarda ve diğer hayvanlarda bakteriyel enfeksiyonların tedavisinde ve önlenmesinde yaygın olarak kullanılmaktadır. Ancak antibiyotiklerin insan ve hayvan sağlığına zararlı etki yapma riski bulunmaktadır. Balıklarda ve diğer su hayvanlarında, ayrıca su ortamında ve diğer ekolojik nişlerde antibiyotiklere dirençli bakterilerin ortaya çıkması, ilaca dirençli bakterilerin ve aktarılabilir direnç genlerinin rezervuarlarını oluşturmuştur. İnsan patojenlerindeki antimikrobiyal ajanlara karşı direnç, insan enfeksiyonları sırasında tedavi seçeneklerini ciddi şekilde sınırlandırmaktadır. Bu derleme, su ürünleri yetiştiriciliğinde yaygın olarak kullanılan antibiyotik türleri, antibiyotik uygulaması, antibiyotik test teknikleri ve su, balık ve sedimentteki antibiyotik direnci hakkındaki bilgileri bir araya getirmektedir. Antibiyotik direnciyle mücadelede karşılaşılan zorluklar, stratejiler ve kısıtlamaların yanı sıra su ürünleri yetiştiriciliğinde antibiyotik kullanımına yönelik beklentiler de tartışılmaktadır.
