Aquaculture continues to significantly expand its production, making it the fastest-growing food production sector globally. However, sustainability of is at stake due predicted effects climate change that are not only a future but also present reality. In this paper, we review potential on aquaculture and implications sector's sustainability. Various elements changing climate, such as rising temperatures, sea-level rise, diseases harmful algal blooms, changes in rainfall patterns,...
Abstract Selenium (Se) is an important micronutrient that has been used in aquafeeds for the normal growth, welfare and health of aquatic animals. Through nanotechnology, Se can be converted into nanoparticles are more bioavailable, utilized absorbed by However, this still a new emerging area research aquafeeds. This paper aims to review effect (Se‐NPs) application on Specifically, different compounds Se, requirement levels species, effects animal physiology, antioxidant capacity immune...
Aquaculture is a significant industry in food production, and its contribution to nutrition security well acknowledged. Zambia’s aquaculture production has continued increase significantly, thus playing key role supplying animal protein sources for human consumption. However, recent estimates show that 75% of the national comes from large-scale commercial producers despite being by far minority while majority small-scale contribute remaining 25% total annual production. This low attributed...
This study investigated the effect of replacing fishmeal with red wigglers (Eisenia fetida) worm meal (RWWM) in diet Nile tilapia (Oreochromis niloticus) fingerlings. Red worms (RWW) were culture on a vegetable by-product medium, harvested and dried to obtain meal. The fish (average weight ± SE: 7.70 0.06 g) fed seven diets (30% crude protein 7.5% lipid), which was replaced 0%, 5%, 10%, 15%, 20%, 25%, 30% RWWM. reared 1000 L fiberglass tanks recirculating aquaculture system hand-fed twice...
Cage aquaculture is among the recent innovations that have attracted great attention in fish production most African countries. In Zambia, cage has recorded significant growth to even emerge as largest contributor total national annually. Our study was aimed at assessing Siavonga district of Zambia. We targeted and feed manufacturing companies, their production, challenges, opportunities. This revealed there were five main companies with cages ranging from 96 m3 135,534 size. Oreochromis...
An 8-week rearing trial was designed to appraise the dietary lysine levels on intestinal antioxidant capacity and immunity of grass carp fry. Six practical diets were prepared with graded (1.44, 1.79, 1.97, 2.44, 2.56 2.87% dry matter), these fed The results showed that activities factors including catalase glutathione peroxidase markedly improved by 2.44% compared control diet (1.44% lysine) ( P < 0.05). In terms antioxidants, diet, upregulated mRNA expression target rapamycin, S6...
This study investigated the effect of Clostridium autoethanogenum protein (CaP) on intestinal absorption, antioxidant status, and immune response genetically improved farmed tilapia (GIFT: Oreochromis niloticus) juveniles. The fish (initial weight 0.7 ± 0.5 g) were fed with diets containing different levels CaP: 0% (control), 5%, 10%, 15%, 20% to partially replace soybean meal. After 8 weeks feeding trial, absorption capacity–related sodium/potassium-ATPase transporter (Na+/K+-ATP) was...
Low-fishmeal and protein-saving diets are two prominent nutritional strategies utilized to address challenges related the scarcity sustainability of protein sources in aquaculture. However, these have been associated with adverse effects on growth performance, feed utilization, disease resistance aquatic animals. To mitigate challenges, exogenous protease has applied enhance quality lower contents or fishmeal alternatives, thereby improving bioavailability ingredients. Additionally,...
The aquaculture sector faces sustainability challenges due to unsustainable feedstuffs. To address this, there's a continuous search for alternatives traditional aquafeed protein sources such as fishmeal. Clostridium autoethanogenum is novel source with long-standing application in the bio-energy industry. With 80–89% crude content on dry matter basis, (CAP) has gained attention nutrition research species. This study aimed review CAP utilization aquafeed, examining its nutritional value and...
Aquaculture plays a critical role in Zambia's food and nutrition security. However, aquaculture is highly vulnerable to the effects of changing climate which can lead economic losses, insecurity. In this study, we investigated perceived change on production Zambia, vulnerability factors, adaptation strategies. We used semi-structured structured questionnaires collect data from producers all provinces across country. Results revealed high (over 80%) awareness change, primarily attributed...
Abstract Fish is an extremely perishable food product which requires proper handling soon after harvest. The present study was aimed at assessing post-harvest fish losses and preservation practices in Siavonga district, Southern Zambia. Structured semi-structured questionnaires were used to collect data on from aquaculture producers, artisanal, commercial fishers. All the fishers who landed lakeshore interviewed, while producers randomly selected based information provided by local...
Fisheries and Aquaculture are among the most popular activities in coastal regions of world. In addition, both correspond to high-risk within a climate change context as they vulnerable environmental changes that threaten socio-economic sustainability fishing communities depend on fish for food security income generation. 2019, central part Mozambique was hit by two unprecedented cyclones: Idai Kenneth killed over 600 people left nearly 2.2 million need urgent assistance. The aim present...
Understanding the variability of heavy metals in surface sediments and how they accumulate is important not only ecology biodiversity conservation but also aquatic natural resources management. This study investigated level some metal contaminants Kifubwa Solwezi Rivers Northwestern Province Zambia. We used an atomic absorption spectrophotometer (AAS) to determine levels sediments. Six sites known be associated with anthropogenic activities were sampled. In these sites, six elements, namely...
This study investigated the application of anaesthetics in 23 private and government-owned hatcheries 10 provinces Zambia. The employed both qualitative quantitative research designs used a structured questionnaire to collect data from respondents. results showed that most (65%) were not using handling fish all (100%) (35%) clove powder as only type. Most respondents (61%) sure or did have information about availability anaesthetic substances their localities while 26% reported wider but 13%...
