Abstract

In this study, the performance of integrated showering type aeration cum feeding system (i-STAFS) a modified design of showering aeration system (SAS) was evaluated and optimized to determine its applicability in tank base aquaculture practices. The experiments were conducted in a fibre reinforced plastic (FRP) tank of dimension 1.7 m x 0.7 m x 0.6 m to study the effects of various geometric and dynamic variables viz., height of water fall (H) (h), diameter of shower hole (d) (D), number of hole in the shower plate (N) (n) and distance between the shower (W) on the key indexing parameters such as Standrad Oxygen Transfer Rate (SOTR), Standard Aeration Efficiency (SAE), feed retention (X1) and water spray area (X2) to analyze the aeration and feeding efficiency of i-STAFS. A schedule of experiments comprising 28 trials designed using Central Composite Design (CCD) was carried out to obtain the optimum values of geometric parameter. Results showed that maximum SAE and SOTR were obtained when H= 1 m, d= 2 mm, N = 80nos, W= 0.8 m. Further, the trials were conducted to analyze the effectiveness of the feeding unit of i-STAFS and the minimum feed retention (X₁)= 0.88 g (out of 250 g) and maximum water spread area (X₂)= 50 cm² was observed when h= 0.6 m, D= 3 mm, n = 60nos. Finally, a performance testing of i-STAFS was done with P.vannamei in comparison with the existing diffuser type aeration system for a period of 25 days in two separate tanks. The test outcome revealed that good water quality parameter conducive of P.vannamei culture is maintained by i-STAFS when compared to the diffuser. Also, the feed consumption ratio (FCR), which is a key parameter for animal growth is significantly low in comparison with diffuser aeration system which indicates a better growth rate and production when operated with i-STAFS.

池型育苗对虾综合淋浴式曝气饲养系统（i-STAFS）优化及性能评价

本研究对综合淋浴式曝气投料系统（i-STAFS）的性能进行了评价和优化，以确定其在池基养殖实践中的适用性。实验在尺寸为1.7 m x 0.7 m x 0.6 m的纤维增强塑料（FRP）水箱中进行，研究了各种几何和动态变量，即瀑布高度(H) (H)、淋浴孔直径(d) (d)、淋浴板孔数(N) (N)和淋浴间距离(W)对标准氧传递率（SOTR）、标准曝气效率（SAE）、进料滞留量（X1）和喷水面积（X2），分析i-STAFS的通气性和进料效率。采用中心复合设计（CCD）设计了28个试验计划，以获得几何参数的最优值。结果表明，当H= 1 m, d= 2 mm, N = 80nos， W= 0.8 m时，SAE和SOTR最大。进一步的试验进行了分析的有效性喂养i-STAFS和最低饲料单位保留(X1) = 0.88  g(250 g)和最大水扩散面积(X2) = 50 cm2观察当h = 0.6  m, D = 3 mm, n = 60号。最后，对i-STAFS进行了为期25天的性能测试，并与现有的扩散式曝气系统在两个单独的池中进行了比较。试验结果表明，与扩散器相比，i-STAFS保持了良好的有利于凡纳滨虾培养的水质参数。此外，与扩散曝气系统相比，动物生长的关键参数饲料消耗比（FCR）显著降低，这表明i-STAFS运行时具有更好的生长速度和产量。

期刊介绍： Aquacultural Engineering is concerned with the design and development of effective aquacultural systems for marine and freshwater facilities. The journal aims to apply the knowledge gained from basic research which potentially can be translated into commercial operations. Problems of scale-up and application of research data involve many parameters, both physical and biological, making it difficult to anticipate the interaction between the unit processes and the cultured animals. Aquacultural Engineering aims to develop this bioengineering interface for aquaculture and welcomes contributions in the following areas: – Engineering and design of aquaculture facilities – Engineering-based research studies – Construction experience and techniques – In-service experience, commissioning, operation – Materials selection and their uses – Quantification of biological data and constraints
