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

Underused Marine Resources: Sudden Properties of Cod Skin Gelatin Gel

Gels, Journal Year: 2023, Volume and Issue: 9(12), P. 990 - 990

Published: Dec. 18, 2023

The main object of this work was to characterize the structure and properties laboratory-made fish gelatin from cod skin in comparison with known commercial gelatins mammalian origin. This is one way we can contribute World Food Program foodstuff resources alternative natural sources. Our research based on combination an expanded set complementary physical–chemical methods study similarities distinctions hydrogels traditional novel sources underused marine resources. In work, have compared morphology, supramolecular colloid two (mammalian fish) extracted cold-water laboratory conditions. obtained results are novel, showing that our laboratory-produced much closer terms such parameters as thermal stability strength structural network under temperature alterations. Especially interesting experimental observations comparing both gelatins: it shown laboratory-extracted essentially more thermally stable its analogue, being even rheological one.

Justification of parameters of impact-spreading finger shaft for grinder-mixer-dryer using the example of eggshells

Eastern-European Journal of Enterprise Technologies, Journal Year: 2024, Volume and Issue: 3(1 (129)), P. 33 - 44

Published: June 28, 2024

The object of the study is to determine critical impact speed during shell destruction, crack formation in shell, and grind shell. When operating a grinder-mixer-dryer, problems arise such as determining on depending height its fall, lack ability fall from certain heights, which complicates planning operation finger shaft. As result research, it was found that an auger with knives crushes moves feed raw materials, impact-spreading shaft ensures partial grinding fragile materials intensive processes mixing drying wet uniform filling installation hopper. appearance cracks when falls 0.15 m has been experimentally recorded. Therefore, this metal surface peripheral shaft, crushing theoretical studies, analytical expression obtained provides determination fall. value fingers determined be 1.66 m/s. experimental results showed effective occurrence grinding, processes. Moreover, within 15 minutes installation, crushed accordance requirements. uniformity reached up 90 % 4 6 operation, proceeded at rate 26.54 per hour.
