In aquaculture, fish are stressed with several factors involved in impacting the growth rate and health status. Although Nile tilapia can resist brackish water conditions, hypoxia status may impair condition of fish. were exposed to salinity at 0, 10, 20‰ for four weeks then behavior was checked. The results showed meaningfully lowered rate, feed utilization, survival when kept weeks. Then subdivided into six groups (factorial design, 2 × 3) normoxia (DO, 6 mg/L) 1 conditions 24 h. High (10...
Abstract The aquaculture sector is steadily growing due to the increasing demand for healthy and cheap animal protein sources. Consequently, high nutritionally balanced aquafeed increases, but requires sustainable feasible feed ingredients. However, cost of fish soybean meals opens door looking suitable non‐traditional processing fruits results in amounts waste by‐products, which are risky environment rich nutritional value. Recycling fruit successfully applied growth performance,...
Aquaculture activity is affected by various environmental factors, including water salinity and high temperatures. The present study investigated the impact of using varying (0, 5, 10, 15 20 ppt) on growth behavior, immune responses antioxidative common carp. Fish were raised under optimal conditions except for 8 weeks; fish then subjected to high-temperature stress (32 °C) 48 h. results indicated a reduced final weight (FBW), gain (WG), specific rate (SGR), condition factor (CF), feed...
Abstract African catfish is a freshwater species with high ability to resist brackish water conditions, but heat stress may impair the health status of fish. Thus, impact varying levels salinity (0, 4, 8, and 12 ppt) was investigated on growth performance, survival rate, blood biochemistry (average weight: 180.58 ± 2.8 g average length: 38 1.2 cm) for 4 weeks; then, fish were stressed temperature (32 °C) 72 h. The performance rate markedly higher in reared 0, 8 ppt than ( p < 0.05)....
The need to replace antibiotics in aquafeed is increasing, and alternative safe substances are now encouraged for sustainable aquaculture activity. Curcumin regarded as a multifunctional feed additive with growth-promoting immunostimulant potential. Thus, this study evaluated dietary inclusion of curcumin at rates 0, 1.5, 2, 2.5, 3% the diets Gilthead seabream 150 days. results showed an improved final body weight, weight gain, specific growth rate, conversion ratio fish treated curcumin,...
The study starts with the analysis of current situation both existing buildings and energy sector in Egypt, analyzing consumption patterns inefficiencies leading to these patterns, then defining nZEB concept familiarize reader its different aspects. empirical part utilizes simulation validate proposed guideline by applying it on an already residential building. detailed steps converting building is final outcome research.
Dietary cinnamon has several bioactive compounds with growth-promoting and immunomodulation potential is suggested for finfish species. This study evaluated the inclusion of at 0, 10, 15, 20 g/kg in European sea bass (
Salinity and freshwater scarcity are significant challenges affecting agriculture production worldwide. Sustaining food in arid semi-arid regions requires innovative, efficient, low-cost technologies. Integrated aqua-vegeculture systems (IAVS) promising technologies for cultivating vegetable crops rearing fish a closed-loop system. The system utilizes effluents as crop fertilizers recycles water increased productivity. Hence, the current study aimed to investigate response productivity of...
Abstract Mangrove forests are among the Nature Based Solutions (NBS) that help in mitigating climate change effects as they sequester carbon dioxide gas four times greater than normal forests. They stabilize coastlines, reduce coastal flooding, and provide nurseries to wildlife. Only two mangrove species exist Middle East: Avicennia marina Rhizophora mucronata , due their high tolerance region’s harsh dry environmental conditions. This paper presents a comprehensive review on current status...
ABSTRACT Hydroponic systems have the potential to be sustainable and alternative methods for food production that confer advantages of high better control growth. However, only a few studies focused on leafy vegetable growth in different subsystems environmental variables. The main objective this study is comprehensively analyze rates, sensory attributes, nutrient uptake lettuce across these hydroponic subsystems—deep water culture (DWC), film technique (NFT), media bed (MB), sandponic...
Selenium (Se) is a multifunctional trace element required in specific amounts for the optimal growth of aquatic finfish species. For this reason, study investigated effect Se nanoparticles on behavior, antioxidative capacity, and liver wellbeing Striped catfish (Pangasianodon hypophthalmus). fed varying levels (0. 0.5, 1, 2 mg/kg) triplicate units kept 60 days. delivered dietary had markedly increased performance, rate (SGR), consumed feed, protein efficiency ratio but reduced feed...
