Protein Source for Fish Feed XVII. Inclusion of Malt Protein Flour to Diet for Fingerling Yellowtail.

The present study was conducted for two months between November 2019 and December 2019 to investigate the growth performance of Nile Tilapia fed with diets containing soyabean 100% (T1), soyabean and Achatina fulica: 50/50% (T2) and A. fulica 100% (T3). The experimental diets were formulated with 45% crude protein content. The stocking density was 30 fingerlings per tank of size 1m*1m*0.8m with three replications for each treatment. The tanks were stocked with the fingerlings of uniform size 9 ± 677 cm and weight 24 ± 0.66g. The experimental fishes were fed twice a day at 5% of their body weight. No significant differences (p˃0.05) in average weight gain, apparent feed conversion ratio (AFCR), daily weight gain, gross fish yield and net fish yield were observed. The study revealed that Giant African Snail (GAS) can be used either as partial or total replacement for soyabean as protein source for the fish. The use of harmful pest A. fulica in fish feed shows bright prospect in reducing the feeding expenses together with its suitable management.

Willingness To Use

The perception of key players in the fish farming sector towards the use of insects is important for their acceptance to adopt insects as an alternative protein source to the expensive fish meal. Perception was established through a cross-sectional study of 208 fish farmers and 71 fish feed traders and/or processors conducted in Gulu, Tororo and Masaka districts in Uganda, using descriptive, Chi-square, correlation and factor statistical analysis of the data collected. Males dominated the fish farming and fish feed trading and/or processing enterprises. Youths were involved to almost the same extent as adults. Fish farmers majorly practiced pond fish farming, mainly using vegetable and grain based feeds. Most fish farmers (94.9%) and feed traders or processors (91.5%) were willing to use insects for feed but only 44.8% of fish farmers and 8.6% of feed traders and processors had ever used insects. All insects ever used by the respondents for feeding fish, including white ants, grasshoppers, termites and cockroaches were not reared but harvested from the environment. Willingness to use (rear/buy/sell) insects as fish feed was significantly and positively correlated with farmers’ and fish feed traders’ and/or processors’ perception that insects were good sources of nourishment for fish. Familiarity with use of insects and knowledge/awareness of their use significantly contributed to respondents’ positive perception. The apparent willingness to use insects for feeding fish should be promoted by encouraging mass insect production. Assessment of the consumer’s acceptability of fish reared on insects is necessary to ensure market for insect-fed fish.

Abstract Moringa (Moringa oleifera) has frequently been studied as an alternative and promising protein source in fish feed. Moringa leaves is among the potential and affordable plant-based protein source ingredient, as it protein, vitamin, beta-carotene, and various kind of minerals. Flavonoid, saponin, vitamin and alkaloids reportedly exhibit immune-stimulating activity which increase immune response. This study aims to evaluate the replacement of fish meal with fermented Moringa leaves meal in feed on the immune response of red tilapia (Oreochromis sp.). The research was conducted experimentally using a completely randomized design by four treatments in triplicate. The treatments include replacement of the fish meal with fermented moringa leaves meal at 0, 10, 20, and 30 %. Red tilapia with total length of 9 to 10 cm was fed twice daily for two months at a feeding rate of 3 % of total biomass. The results showed that replacement fish meal with fermented Moringa leaves meal as much as 20 % increases the percentage values of hematocrit and leukocrit, stimulates phagocytic activity and phagocytic index, suppresses monocyte and increases lymphocytes, and increases total plasma protein.
