In the food-energy-water (FEW) nexus, livestock has a dominant place. It is generally considered as water, energy and land-intensive. Aquaculture could provide additional animal protein contribute to meeting food demand. However, aquaculture requires natural resources causes freshwater pollution due aquafeed, fertilizer, hormone use. This study assesses sustainability of using indicators water ...

Long chain polyunsaturated fatty acids (LC-PUFA), namely those from omega-3 (n-3) and omega-6 (n-6) families, are paramount for both fish human nutrition. Some of these biomolecules cannot be synthesized de novo must acquired through the diet, being termed dietary essential (EFA). Fish requirements EFA have traditionally been met incorporation oil (FO) in formulation aquafeeds. However, with li...

An overview is given on recent developments in insects as food and by reviewing the literature which has appeared during last few years edible insects. outlook to future provided. About a decade ago, attention shifted from harvesting tropics farming all over world for feed applications. Most production targeted towards pet food, but it will turn aquafeed next two decades. More than 80% of publi...

In aquaponics and circular multitrophic food production systems, dietary protein source, as well fish species choice, particularly in cases of different nutritional physiology, could be factors affecting excreted nutrient profiles. Accordingly, growth performance, dissolved accumulation feces profiles were evaluated for African catfish (Clarias gariepinus) reared recirculating aquaculture syste...

Abstract Africa’s contribution to world aquaculture production in 2018 is still insignificant (2,196,600 tons; ~ 2.7%) albeit significantly increasing with larger-scale investments Egypt (1,561,457 tons), Nigeria (291,233 and Uganda (103,737 tons) producing substantial quantities (91%) of the total fish from region. The quantitative SWOT technique multi-attribute decision-making method (MADM) w...

Abstract Reducing the use of fishmeal (FM) in aquafeed means a significant saving amount FM at global level and reducing environmental impacts. One potential protein sources to replace shrimp diet is insects’ meal. Therefore, present study aimed examine effects replacing with mealworm (MW; Tenebrio molitor ) on growth, digestive enzymes activity hepatopancreatic biochemical indices Pacific whit...

Dried or defatted black soldier fly (Hermetia illucens) larvae meal has been shown an important ingredient in aquafeed, but little information is available about the effects of pulp (BSFP) on growth and health fish. A 62-day feeding trial was conducted to assess dietary BSFP performance, whole body composition, serum metabolites, antioxidant immune response Micropterus salmoides. Four isoprotei...

The capacity of utilising a single cell protein (SCP) ingredient coming from Corynebacterium glutamicum was assessed on adult grey mullet ( Mugil cephalus ) reared in captive conditions. experiment carried out using triplicate groups 68 g average initial body weight. Three diets, SCP0, SCP10 and SCP20 with increasing inclusion SCP (0%, 10% 20%) substitution soybean, poultry fish meal were formu...

The nutritional and microbial safety of fish feeds were investigated in this study. Commercially available feed brands (Eco-float, Skretting, Top-Feeds, Blue Crown) procured from sales outlets Ogun State, Nigeria. Moisture ranged 8.15 to 8.82 these values not significantly different (p>0.05) except for Topfeed. Skretting had the highest crude protein value (48.49±0.03) while Ecofloat recorde...

Abstract Background The aquaculture sector is the biggest consumer of fishmeal and demand this ingredient higher than production. replacement from aquafeed a current research thrust. has been possible with plant ingredients in many fish species, however, possesses some limitations terms low digestibility inadequate nutrient profile. Results Complete diets Cirrihinus mrigala was studied using sp...
