Abstract:
Soil salinity and freshwater scarcity are among the major global threats to sustainable development owing to their adverse impacts on agricultural productivity especially in arid and semi-arid regions. There is a need to find sustainable alternatives such as salt-tolerant crops and fish to improve people\'s livelihoods in marginal areas. This study aimed to maximize the growth and yield of striped catfish (Pangasianodon hypophthalmus) and quinoa (Chenopodium quinoa) cultivated under a biosaline integrated aquaculture-agriculture system. The study was laid in a randomized completely block design of three saline effluent treatments under three replicates: 5000 ppm (T1), 10,000 ppm (T2), 15,000 ppm (T3), and control (T0). Agro-morphological and physiological attributes of quinoa were measured. The crop yield in biomass and mineral element composition was also studied. Additionally, fish growth performance parameters such as feed intake and efficiency, growth, and survival rate were also calculated. Our results indicated that irrigating quinoa with saline aquaculture effluents above 10,000 ppm enhanced the plant growth, yield, and nutrient content of seeds. Furthermore, rearing striped catfish in saline water reaching up to 15,000 ppm did not have adverse impacts on the growth and survival of fish. Overall, integrating catfish and quinoa production under a salinity regime of 10,000 ppm could be a potential solution to ensuring alternative food sources in marginal areas.
摘要:
土壤盐分和淡水短缺是可持续发展面临的主要全球威胁之一,因为它们对农业生产力产生不利影响,特别是在干旱和半干旱地区。有必要寻找可持续的替代品,如耐盐作物和鱼类,以改善边缘地区人们的生计。这项研究旨在最大程度地提高在生物盐水综合水产养殖-农业系统下种植的条纹cat鱼(Pangasianodonhypothromus)和藜麦(Chenopodiumquinoa)的生长和产量。该研究是在三个重复下的三个盐水流出物处理的随机完全块设计中进行的:5000ppm(T1),10,000ppm(T2),15,000ppm(T3),和控制(T0)。测定了藜麦的农业形态和生理属性。还研究了作物产量中的生物量和矿质元素组成。此外,鱼类生长性能参数,如采食量和效率,增长,并计算了生存率。我们的结果表明,用超过10,000ppm的盐水水产养殖废水灌溉藜麦可以增强植物的生长,产量,和种子的营养成分。此外,在高达15,000ppm的盐水中饲养条纹cat鱼不会对鱼类的生长和存活产生不利影响。总的来说,在10,000ppm的盐度条件下整合cat鱼和藜麦的生产可能是确保边缘地区替代食物来源的潜在解决方案。
