In Africa, many governments and development agencies have promoted aquaculture as a panacea for household food security, rural development, poverty reduction. However, production in the continent remains low despite significant investments research technology development. While numerous initiatives been directed at technological innovation transfer, their present scale of uptake is very slow therefore inadequate to achieve transformational change envisaged 2030 Agenda sustainable this paper,...

As capture fishery sector continues to decline, aquaculture industry must be accelerated bridge the fish supply gap especially in developing countries. However, most countries, is characterized by low productivity due inefficient technologies, hence need for innovative aqua-technologies that can stimulate back yard production, enhanced livelihood security among smallholder farmers. In aquaculture, biofloc technology (BFT) considered as an culture system with great potential production. The...

Abstract Nile tilapia ( Oreochromis niloticus ) is one of the most farmed fish globally, with a significant contribution improving local livelihoods, especially in developing countries. was first cultured Kenya 1924 and species. Annually, O. accounts for 62% (∼15,000 tonnes) total aquaculture production. Although preferred fish, its culture faces challenges, example, early maturation due to prolific breeding behaviour leading stunted growth that limits profitability among smallholder...

A total of 52 samples finished fish feeds and ingredients were collected from smallholder farmers in Kenya, Tanzania, Rwanda Uganda, analyzed. Culture molecular techniques used to identify fungal isolates the feedstock, mycotoxin profiles determined using liquid chromatography–tandem mass spectrometry. The most prevalent species recovered was Asperigillus flavus (54.5%). Other Aspergillus tamarii (9.1%), Mucor velutinosus (9%), Phoma sp. (6.1%), niger (6%), Eurotium rubrum (3%) Penicillium...

In Sub-Saharan Africa, Nile tilapia (Oreochromis niloticus L.) make up over 80% of aquaculture production. However, the local farmers are restricted by unavailability and expensive cost formulated rations. To reduce reliance on scarce fishmeal used in fish feeds, alternative insect protein has been successfully utilized many aquafeeds. data influence insect-based feed growth economic benefit feeding with emerging diet scanty. This study investigated effect partially completely substituting...

Abstract Kenya is a major player in the global ornamental trade, exporting substantial quantities of fish to market. The sector plays an important role country's economy through foreign exchange. However, industry has not fully developed generate more economic benefits. This paper sought identify existing opportunities for enhancing production and trade country. findings reveal that there are collection native freshwater species from vast resources country; culture marine fish; public...

Lack of suitable diets for semi-intensive production Oreochromis niloticus in Kenya has necessitated use expensive designed intensive production. To address this problem, two isonitrogenous (24% protein) were formulated and evaluated O. fertilized ponds. One diet contained vitamins minerals premix (CV) while the other had no (CW). Growth fish fed on feeds was compared with groups commercial pig pellets (PP) wheat bran (WB). There significant differences mean weights, growth rates feed...

Insect meals have the potential to be used as a source of nutrients in aquafeeds due their high nutritional profile and cost effectiveness. The objective this study was elucidate impact black soldier fly larvae meal (BSFLM) replacement for fish (FM) on Nile Tilapia (Oreochromis niloticus, L) growth performance, survival rate, somatic indexes economic benefits. Four experimental diets were prepared; three with BSFLM substitute FM at 25% (T25%), 50% (T50%) 75% (T75%) control diet without (T0%,...

This study evaluated the effect of replacing fish meal (FM) with black soldier fly (Hermatia illucens) larvae (BSFLM) on growth performance and economic efficiency Nile tilapia (Oreochromis niloticus) production. The BSFLM replaced FM at 0, 25, 50 75% (T1, T2, T3, T4, respectively). One thousand two hundred (1,200) all-male fry were stocked in twelve hapas Kenya Marine Fisheries Research Institute (KMFRI), Sangoro aquaculture research station Kenya, hand-fed four times daily for 21 weeks....

Nile tilapia (Oreochromis niloticus L.) was fed rice bran (RB), wheat (WB) and maize (MB) at 1.5% body weight. Fingerlings averaging 14 g were stocked 19 462 fish ha−1 in three treatments with six replicates per treatment. Clarias gariepinus 250 to reduce the density of fry. Growth economic performance compared for days 0.08 ha fertilized ponds. Fish growth highest (P < 0.05) MB least RB WB treatment intermediate. Feed conversion ratio similar > 0.05), but significantly higher than Water...

Abstract This study examined the efficacy of community‐level fishery co‐management organizations called Beach Management Units ( BMU s) along Kenyan shores Lake Victoria. s were established to enhance sustainable Victoria management through increasing level community participation assist in administration fisheries rules and regulations by, for, fishers. Inefficiencies have emerged, however, inhibiting effective execution by s. Data collected from 36 Descriptive inferential analyses...

Comparative growth performance of male monosex and mixed sex Nile tilapia (Oreochromis niloticus) was conducted in six earthen ponds each measuring 150 m 2 at the Kenya Marine & Fisheries Research Institute (KM-FRI), Kegati Aquaculture Station.Male O. niloticus juveniles an average weight 12.2 ± 0.02 g length 7.6 cm were collected from nursery production ponds.The obtained by feeding newly hatched with feed dosed 17--methyltestosterone hormone for a period one month.Stocking 3 juvenile -2...

The dwindling capture fisheries has triggered an increase in Kenya's annual fish demand deficit, currently estimated at 553,000 MT. With the adoption of sustainable policies, aquaculture can bridge and surpass this deficit. farming environment is however characterized by its highly fragmented production farms, which limit dynamism technical change needed to commercialize aquaculture. global trend commercialization food through consolidation farmlands. For example, most farms United States...

Abstract Lake Jipe, is a shared water resource between Kenya and Tanzania located at the East African Coast under multiple pressures. The present study assessed current state of Jipe its biodiversity dilemma. Random sampling was conducted 14 points set equidistant parallel to each other. Sampling depths location coordinates were measured using Solar Transducer GPSMAPS® 65 s. In situ quality parameters YSI Pro Plus multiparameter; samples for nutrients analysis collected preserved in cooler...

It is evident from scientific studies that black soldier fly larvae can replace the widely used fishmeal, which costly and unsustainable for smallholder farmers, in aquafeeds. The purpose of this study was to evaluate factors t influencing fish farmers' awareness use meal as an ingredient feeds. effect socioeconomic status aquaculture practices on their awarenessabout based aquafeeds examined using a binary logit regression model. analysis results revealed farming experience (β = 0.327; p...

This study investigated sunflower seed meal (SSM) as dietary protein replacement of fish (FM) for Nile tilapia (Oreochromis niloticus) juveniles (initial mean weight 19.8 ± 6.3 g) reared in earthen ponds 210 days. SSM replaced 25%, 50%, 75%, and 100% (i.e., D25, D50, D75, D100, respectively) FM an isonitrogenous isocaloric diet. The optimum level D25 predicted by the equation y = 177.5 + 26.5x – 7.9x2 yielded about 184 g within 100 Thus was most effective growth ponds. Fish declined exceeded...
