“…Therefore, pH is a determining factor in the risk of fish and shrimp being poisoned with ammonia. In his paper, Mustapha (2019) [10] summarises the effects of pH variation on warm water such as Tilapia and Catfish in the following table, the desired ranges of 6.5 pH to 9 pH level for fish breeding.…”

Water quality in breeding tank plays a significant role when breeding the fish because optimal water quality is significant as these environmental changes will affect young fish to grow successfully. In order to ensure an optimal water quality in the fish breeding tank, an automatic and IOT based monitoring system is essential to replace the conventional monitoring which is done manually. In this paper, Jade Smart 1.0 was developed as a IoT based monitoring system of water quality in the breeding tank which consists of three identical boxes equipped with ESP32 as microcontroller, pH sensor, water temperature sensor and water turbidity sensor. This smart monitoring system is capable to digitally collect, store and display the water quality data in real-time through web and mobile phone applications. Jade Smart 1.0 was tested with three different points known as point A, point B and point C, in real local fish breeding tank in Seremban 2, Negeri Sembilan. Point A was located at the incoming water source, point B, at the corner of the tank opposite of the incoming water and point C, at the corner opposite of point B. The result showed that the average pH level at three locations for water depth of 10cm was pH 6.48 and at water depth of 20cm, dropped to pH 6.40. The maximum difference was 2.6% while the minimum difference was 0.6%. For water temperature at three locations at the water depth of 10cm, the average reading was 28.6°C while for water depth of 20cm, the average reading dropped to 28.3°C. The maximum difference of 1.7% and minimum difference of 0.3% were found. Next, for water turbidity, the location A measured an average of 3.3NTU while location B and location C measured an average reading of 9.8NTU and 9.9NTU respectively.

In recent decades, the aquaculture industry has seen exponential growth worldwide, surpassing other food production sectors. This review aims to explore the dynamics of aqua feed production, particularly the shift from conventional to local feed production in Africa, driven by cost-effectiveness and the availability of raw materials. This review examines various scientific publications on aqua feed, focusing on both conventional and novel feed formulations and their impact on both small-scale and large-scale aquaculture. Commonly used aqua feed ingredients among African farmers include cassava, maize gluten, groundnut oilcake, sunflower oilcake, soybean meal, kale, peas, garlic, shrimp wastes, and waste blood. Novel ingredients such as insect-based diets, micro-algae, and fish discard formulations are also explored. Aqua feed composition impacts aqua waste, water quality, algae, oxygen demand, fish mortality, and eutrophication, and findings from literature reiterate the need to reorient feed formulation methods and ingredients to achieve a circular economy in Africa. This will entail promoting increased fish production at minimal costs and creating employment while supporting climate adaptation and mitigation efforts. Ultimately, the aqua feed sector has the potential to grow sustainably through the adoption of feed alternatives that prioritize sustainable production and encourage beneficiation studies.
