“…However, a 100% replacement of BSFM with PM in the PM diet did in fact lead to a significantly better growth and feed conversion performance compared to both the MIX and the BSF diet. On the one hand, this matches the consensus of poultry by-product meal being a nutritionally highly valuable protein ingredient in aquaculture diets [36,38,39] which can replace up to 100% of the fish meal in control diets of various freshwater fish [37] and serve as an effective and cheap protein ingredient in African catfish diets [10,61]. On the other hand, these results illustrate the apparent superiority that PM can have over BSFM at high dietary inclusion levels.…”

“…In this sense, the traditional objective in aquaculture feed formulation of minimizing the excretion of eutrophication-inducing nutrients such as P [32][33][34][35] does not apply and aquaponic or CMFS diets can feature a substantially higher inclusion of, e.g., phosphorus-rich ingredients such as poultry by-product meal (PM). PM is an established alternative to fish meal [36][37][38][39], and has not only been proven to enable good fish performance even when used as the sole protein source in diets for Nile tilapia (Oreochromis niloticus) and African catfish (Clarias gariepinus), but also to increase soluble reactive phosphorus (SRP) excretion versus an entirely marine fish meal-based diet [10,11].…”

Closing Nutrient Cycles through the Use of System-Internal Resource Streams: Implications for Circular Multitrophic Food Production Systems and Aquaponic Feed Development

In order to further close nutrient cycles of aquaponic systems, it could be possible to integrate a third trophic level in the form of insect larvae production (i.e., black soldier fly larvae) to recycle internal waste streams into valuable nutrients. This would present opportunities to formulate sustainable circular aquafeeds that combine these internally available nutrients with complementary external raw materials. The ingredient composition of feeds for such circular multitrophic food production systems (CMFS) may affect fish performance as well as excretion of important dissolved plant nutrients such as N, P and K. Hence, fish meal from catfish processing (CM) as base ingredient was combined with variable levels of poultry by-product meal (PM) and black soldier fly larvae meal (BSFM) into three marine-ingredient-free experimental diets corresponding to hypothetical production scenarios of a CMFS that aims to integrate aquaponics with insect larvae production. These experimental diets and a commercial diet (COM) were compared using isonitrogenous and isolipidic formulations. They were fed to African catfish (Clarias gariepinus) in recirculating aquaculture systems (RAS) and evaluated concerning growth performance and nutrient excretion. All diets resulted in similar total inorganic nitrogen (TIN) excretion, whereas the increase of dietary PM inclusion from 0% (BSF diet) to 20% (MIX diet) and to 41% (PM diet) and concomitant reduction of BSFM inclusion led to increasingly higher soluble reactive phosphorus (SRP) excretion per unit of feed compared to the COM diet. While the PM diet enabled the best growth and feed conversion performance, the MIX and especially the BSF diet produced more similar performance to the COM diet, which generated the highest dissolved K excretion. The MIX and the PM diet resulted in the highest Ca and P, yet lower N content in the fish feces. Results indicate that combining CM with elevated levels of PM in the diet of African catfish could improve growth performance and reduce the need for P fertilization in aquaponics when compared to industrial diets optimized for low environmental impact. Findings are discussed regarding their implications for CMFS and aquaponic feed formulation.

“…Poultry by-product meal is a valuable and widely used protein source in aquafeeds due to its high protein content, balanced amino acid profile and ample mineral content [71][72][73] and can successfully replace up to 50-100% of fish meal in diets for a variety of freshwater fish species [74]. Considering that 100% of the FM was replaced in the present study and diets only incorporated a single main protein ingredient at high absolute inclusion levels, the PM diet held up fairly well against the FM control diet, especially in comparison to the BSF and the PBM diet, and results are in general agreement with [74].…”

Toward Feeds for Circular Multitrophic Food Production Systems: Holistically Evaluating Growth Performance and Nutrient Excretion of African Catfish Fed Fish Meal-Free Diets in Comparison to Nile Tilapia

In aquaponics and circular multitrophic food production systems, dietary protein source, as well as fish species choice, particularly in cases of different nutritional physiology, could be factors affecting excreted nutrient profiles. Accordingly, growth performance, dissolved nutrient accumulation and feces nutrient profiles were evaluated for African catfish (Clarias gariepinus) reared in recirculating aquaculture systems (RAS) and fed single protein source diets based on black soldier fly larvae meal (BSF), poultry by-product meal (PM), poultry blood meal (PBM) and fish meal (FM) and the results were compared to previous findings for Nile tilapia (Oreochromis niloticus). All diets resulted in significantly different growth performances of African catfish, with FM producing the best growth performance, followed by PM, BSF and PBM. PM resulted in the highest soluble reactive phosphorus concentrations (SRP) in the RAS water; whereas, BSF resulted in the highest K, Mg and Cu concentrations. The highest feces nutrient density was recorded for PBM; whereas, FM and PM yielded the lowest feces nutrient density. Comparing African catfish to Nile tilapia revealed that the former showed significantly better growth performance with FM and PM, however, significantly weaker performance with BSF. Although dissolved K accumulation was similar between species across diets, significant differences were recorded for total inorganic nitrogen and SRP production per unit of feed for individual diets. Despite similar feces nutrient profiles, African catfish produce significantly less feces dry matter per unit of feed for each diet compared to Nile tilapia. Findings are discussed regarding their implications for aquafeed development in the context of circular multitrophic food production systems.

“…Among these, fish meal is a traditional choice. Another group of alternative protein components used in fish diets are byproducts from the oil industry, such as oil cake and meal extracted from sunflower and peanut 19 . Additionally, plant protein sources like soybean meal, cotton seed meal and aquatic plants like Lemna minor, Azolla pinnata, Hydrodictyon reticulatum, Potamogeton gramineus and Ceratophyllum demersum can be utilized.…”

Background and Objective: Aquaculture is a widely practised agricultural method globally, which involves raising aquatic organisms in suitable environmental conditions. Its main objective is to meet the increasing demand for fish and reduce reliance on fish imports and fishery products. Materials and Methods:In the present study, spotted tilapia, Pelmatolapia mariae, obtained from the local market were fed with artificial diets, namely Diet 1, Diet 2, Diet 3, Diet 4 and Diet 5. Over a period of 28 days, the live weight, standard length, total length and biochemical composition (protein, carbohydrate and lipid) of the fish were monitored every 7 days. Results: After the 28 days period, the control group exhibited higher total length and standard length, while Diet 5 resulted in a higher live weight. Fish fed with Diet 5 also showed a higher protein content. Carbohydrate content was found to be higher in fish fed with Diet 3 and the control group. On the other hand, the control group had a higher lipid content. Conclusion: Considering the superior growth and biochemical constituents observed in fish fed with Diet 5, it is recommended to incorporate chicken wastes such as legs and intestines, as well as agricultural byproducts like cauliflower leaves and moringa, into artificial fish feed. This can potentially enhance the overall performance and productivity of aquaculture systems.
