Fish Meal Replacement

Abstract Black soldier fly larvae (BSFL) meal-based diet is an innovative strategy for sustainable 24 aquaculture. In the present study, black soldier fly larvae meal has shown a promising 25 alternative as a fish meal (FM) replacement in diets for common carp fry. Black soldier fly 26 larvae; a protein, fat and minerals containing non-pest insect, when used as fish feed ingredient 27 minimize feed cost, boost up fish production and tackle environmental hazards. Five feeds were 28 formulated where fish meal was replaced by BSF larvae for nursing of common carp fry. Feeds 29 were prepared by 100 (T1), 75 (T2), 50 (T3), 25 (T4) and 0% (T5) replacement of fish meal with 30 BSF larvae as a protein and minerals supplement. Among the feeds T3 performed better than 31 T1. Most of the common carp fry were healthy and robust in treatment T1 and T3 where %weight 32 gain was 417.70% and 427.95%, respectively. The lower feed conversion ratio (FCR) was also 33 obtained in treatment T1 (3.54) and T3 (3.42) whereas, higher FCR was found in T4. However, 34 at harvest, the highest fry production was obtained with T1 (3.10 tons/ha/60 days) where 100% 35 fish meal was replaced by BSF larvae. Therefore, 100% fish meal can be replaced by BSFL 36 easily to address the protein scarcity, adulteration and environmental hazards.

Fish Meal Replacement

Fish farming faces the challenge of the high cost of feeds because of the cost of high-quality protein like fish meal required in food formulations. Therefore, the need for alternative protein sources is much needed. Black soldier larvae (Hermetia illucens) are alternative feed containing high protein. BSF larvae contain high protein levels (42.7% dry matter; DM). Fish diets should contain 32% to 45% protein content. Therefore, it can be a substitute for a fish meal. This study was conducted to investigate the effect of freshwater fish meal replacement with black soldier fly larvae meal (BSFLM) on the growth rate of Clarias gariepenus fingerling.  The effect of freshwater fish meal replacement with black soldier fly larvae (BSFLM) was investigated. This study involved the cultivation of Clarias gariepenus fingerling given BSFLM and a commercial diet. The results showed a difference between the weight gains of C. gariepenus, which were 6.46g in BSFLM, while the commercial diet was 1.9g during 28 days of experiments. There was also  no significant difference (p <.05) in the mean weight gain, specific growth rate (SGR), and survival rate. Using BSFLM as an alternative source of protein in fish farming can reduce costs in the aquaculture industry without changing its quality.

The Impact

The acceptance of eco-friendly black soldier fly larvae meal (BSFLM) as sustainable alternative protein ingredient in poultry feeds continues to gain momentum worldwide. This study evaluates the impact of BSFLM in layer chick and grower diets on the growth, carcass quality and economic returns. Mean weekly weight gain and total live weight per chick and grower varied significantly. The highest final weight gain was achieved when birds were provided diet with 25.6% BSFLM. Average daily feed intake (ADFI), average daily weight gain (ADG) and overall weight gain of the chick varied significantly, except for the feed conversion ratio (FCR). For grower birds, ADFI, ADG, FCR and overall weight gain did not vary significantly across the various feeding regimes. The weight of the wings and drumsticks had a quadratic response with a maximum weight obtained at 33% inclusion of BSFLM. The weight of the internal organs were not significantly affected by dietary types. Positive cost–benefit ratio and return on investment was recorded for diet types with higher BSFLM inclusion levels (>75%). Diets with 25% and 100% BSFLM inclusion were the most suitable and cost-effective, respectively. Thus, BSFLM represents a promising alternative source of protein that could be sustainably used in the poultry industries.

Abstract Black soldier fly larvae (BSFL) is an alternative protein source for animals, including dogs and cats. The larval diet may affect their nutrient composition and overall nutritional value. Calcium carbonate (CaCO3) and calcium chloride (CaCl2) are common Ca sources, but differ in solubility (CaCO3 is insoluble; CaCl2 is soluble), so their intestinal absorption may differ. In addition, the Ca form and concentration may decrease mineral utilization and nitrogen digestibility, thereby affecting feed conversion efficiency. Our objective was to determine the effects of different forms and concentrations of Ca on true nutrient and amino acid (AA) digestibility of BSFL intended for use in animal feeds using the precision-fed cecectomized rooster assay. All animal procedures were approved by the University of Illinois Institutional Animal Care and Use Committee prior to experimentation. 16 cecectomized roosters (4 roosters/substrate) were randomly assigned to test substrates. All contained 0.2% Ca in the commercial diet and additional Ca in these amounts and forms: BSFLA: 1.33% CaCl2; BSFLB: 1.0% CaCO3; BSFLC: 0.6% CaCO3; BSFLD: 0.5% CaCO3 + 0.7% CaCl2. After 24h of feed withdrawal, roosters were tube-fed 20g of test substrates. Following crop intubation, excreta was collected for 48h. Endogenous corrections for AA were made using 5 additional cecectomized roosters. All data were analyzed using SAS 9.4. True macronutrient and AA digestibilities were not different among substrates. Digestible indispensable amino acid score (DIAAS)-like values were calculated to determine protein quality according to AAFCO and NRC recommended allowances for dogs and cats. Although AA digestibilities did not differ among groups, those containing CaCO3 generally had higher DIAAS-like values than the diet containing CaCl2 alone (BSFLA). Threonine, methionine, and arginine were often the first-limiting AA. Our results suggest that Ca source fed to BSFL did not affect AA digestibility and protein quality, despite affecting total calcium content of the BSFL.

This study was aimed to evaluate the effect of conventional ingredients replacement with alternative ingredients on growth performance, carcass quality, nutrient digestibility and intestinal microbial of broilers. One hundred twenty Cobb500 broiler chicks were randomly assigned to four diets. Corn, soybean meal and fish meal were replaced with rice waste, meat and bone waste and black soldier fly larvae (BSFL) at 0, 10, 30 and 50% to form four treatments. Body weight gain, feed conversion ratio and digestibility of crude protein and fat were improved in broilers fed the replacement diets. Feed intake was not affected by the treatments suggesting that the replacement diets were well accepted by the chicken. Escherichia coli was decreased in the cecum and Lactobacillus were increased in the intestines of broilers fed the replacement diets. The fiber and chitin contents in the replacement diets may alter intestinal bacterial fermentation leading to improved nutrient digestibility. However, abdominal fat percentage increased in broilers fed the replacement diets. In conclusion, conventional ingredients can be replaced with up to 50% rice waste, meat and bone waste and BSFL in the diets with promising effect on growth performance, nutrient digestibility and intestinal microbial populations. © 2021 Friends Science Publishers

Black soldier fly larvae (BSFL; Hermetia illucens) are known as an alternative feed for livestock, but their lack of polyunsaturated fatty acids (such as eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA)) makes it less valuable. To overcome these problems, BSFL substrate (chicken feed) was fortified with squid liver oil (SLO) at five different concentrations (0, 2.5, 5, 10, and 20%). The growth rate, feed conversion, and nutritional content of BSFL were evaluated at day 15 of rearing. Of the five concentrations, SLO 5% showed the highest growth increase (25.82-fold) among the other treatments (20.63-22.98-fold; P<0.05). The fortification of SLO 5% did not result in differences in survival and feed conversion of larvae compared to larvae fed the control substrate. By rearing BSFL in a substrate containing SLO 5%, the lipid content of the larvae was 32% higher than that of larvae fed the control substrate (P<0.05). The accumulation of lipids was faster in the substrate containing SLO 5% (33.20% for 8 days) than in the control substrate (24.36% for 15 days). The control group of BSFL contained no DHA or EPA, but after rearing on the SLO 5% fortified substrate, the larvae contained DHA at an average level of 2.99 g/100 g lipid and EPA was 2.68 g/100 g lipid. Harvested larvae from SLO 5% treatment was within safe levels of Pb, Cd, As, and Hg (840, 370, 860, and 26.7 μg/kg, respectively), under the EU threshold for animal feed. Based on our results, it concluded that BSFL enriched with PUFAs, DHA and EPA can be considered as important nutritional components of animal feed without excessive heavy metals accumulation by feeding SLO in an appropriate amount.

Abstract Fish feed is the most essential necessity and the biggest contributor on production cost of fish cultivation. As much as 50-70% production cost is for fish feed. It can be deducted by made alternative fish feed. Black soldier fly larvae is an alternative fish feed with high protein content and most importantly it is cheap. The aim of this research was to evaluate the growth and nutrition content of black soldier fly larvae which cultivated in different medium. Medium used in this study was combination of coconut pulp residue and three other different medium, such as tofu dregs, sago dregs, and rice bran. Each combination had three different level of concentration, 1:1, 1:3, 1:5 (w:w). It was evaluated for nutrition content (proximate analysis), biomass, and dried yield. The result showed combination of coconut pulp and sago dregs 1:5 produced the highest biomass (465 g), but black soldier fly larvae produced from combination of coconut pulp residue and tofu dregs 1:3 had the highest protein content (39.78%). The best medium to produce black soldier fly larvae based on multiple attribute decision making (MADM) method was from the combination of coconut pulp residue and sago dregs 1:5 (w:w). It had 465 g biomass, 186 g dried yield, 23.73% protein, 47.67% fat, and 22.15% carbohydrate.

Quadratic Effects

Using black soldier fly larvae meal (BSFM) in place of fishmeal is an ingenious strategy for sustainable fish aquaculture. However, BSFM has not been evaluated for dusky kob (Argyrosomus japonicus), an economically important fish in South Africa. Therefore, this five-week study investigated the effect of partially replacing fishmeal with BSFM on feed utilization, growth performance, and blood parameters of juvenile dusky kob in a recirculating aquaculture system. Four diets were formulated by replacing fishmeal in a commercial dusky kob diet with BSFM at the rate of 0 (BSFM0), 50 (BSFM50), 100 (BSFM100), and 200 g/kg (BSFM200). Fish length and weights were measured weekly, while blood analyses were performed at the end of Week 5. For fish length and weight gain, there were neither linear nor quadratic responses in Weeks 1–4, while quadratic trends (y = 14.77 (± 0.19)−0.11 (± 0.05)x + 0.01 (± 0.00) x2; R2 = 0.35 and y = 49.85 (± 1.53)−1.22 (± 0.39)x + 0.06 (± 0.02) x2; R2 = 0.47, respectively) were observed in Week 5 in response to BSFM levels. Quadratic effects (y = 1.75 (± 0.15) + 0.10 (± 0.04)x − 0.01 (± 0.00) x2; R2 = 0.39) were also observed for feed conversion ratio (FCR) in response to BSFM inclusion levels. Fish fed BSFM200 had a similar overall FCR and specific growth rate as those reared on BSFM0. All blood parameters fell within the normal range for the dusky kob. We concluded that 20% dietary replacement of fishmeal with BSFM does not compromise feed utilization and growth performance of juvenile dusky kob.
