Availability of black soldier fly meal as an alternative protein source to fish meal in red sea bream ( Pagrus major , Temminck & Schlegel) fingerling diets

Abstract

Black soldier fly meal (BM) is an outstanding candidate as a fish meal (FM) substitute because it contains relatively high protein and essential amino acids. In this study, we replaced FM in red sea bream diets (Pagrus major) with BM to investigate its effect on growth and feed utilization. Six isonitrogenous and isolipidic experimental diets were prepared by substituting 0%, 20%, 40%, 60%, 80% and 100% FM protein with BM (Control, BM20, BM40, BM60, BM80 and BM100, respectively). After the 8-week feeding trial, final body weight, weight gain, specific growth rate and feed efficiency decreased linearly with increasing dietary BM level (p < 0.05). Apparent digestibility of protein and fat and serum total cholesterol concentration decreased with increasing dietary BM levels (p < 0.05) Final body weight, WG, SGR and FE against dietary BM level had breaking points of 76.2%, 41.7%, 76.5% and 60.0%, respectively, in segmental regression analysis. In conclusion, the results suggest that BM can replace a maximum of 41.7% of FM in the diet of red sea bream without compromising growth performance or feed efficiency for 56 days.

Bioavailability of porcine blood meal as a fish meal substitute in the diet for red sea bream ( Pagrus major , Temminck & Schlegel) fingerling

“…Over the past few decades, the availability of plant‐based protein sources such as soybean meal and corn gluten meal and animal by‐products such as meat and chicken meals has been widely investigated (Gatlin et al, 2007; Hardy, 2010; Shukla et al, 2019). Furthermore, in recent years, research on new raw materials such as insect meal (Mente et al, 2022; Takakuwa, Tanabe, et al, 2022; Yamamoto et al, 2022) and bacterial cell meal (Adeoye et al, 2021; Zhang et al, 2022; Zhu et al, 2022) has also progressed, and attempts to further reduce the usage of FM continue to expand. However, it has been reported that these substitutes have certain disadvantages, such as decreased growth performance (Burr et al, 2012; Chen et al, 2019), low nutrient digestibility (Drew et al, 2007) and feed intake (Arndt et al, 1999; Kissil et al, 2000), increased anti‐nutrient factors (Francis et al, 2001) and deformation of intestinal tissues (Krogdahl et al, 2003; Yamamoto et al, 2007), when included in the feed in excess of permissible levels.…”

“…The red sea bream is carnivorous and feeds on a wide range of prey organisms such as polychaetes and fish, with shrimp as the main feed (Shimamoto & Watanabe, 1994). Many FM substitutes have been studied for preparing compound feeds for red sea bream (Dossou et al, 2018; Kader et al, 2012; Takakuwa, Tanabe, et al, 2022), and efforts are also being made towards FM‐free feed (Aoki et al, 2000; Tola et al, 2019). However, to the best of our knowledge, no study has examined the effect of gradually replacing FM in red sea bream feed with BM to evaluate its performance as a fish meal substitute.…”

Immune Responses of the Black Soldier Fly Hermetia illucens (L.) (Diptera: Stratiomyidae) Reared on Catering Waste

“…In addition to being robust decomposers, BSF larvae contain significant amounts of protein and lipids and have gained substantial interest as a dietary supplement to feed chickens, swine and fish [ 13 ]. In particular, the replacing of the dietary high-value and unsustainable fish meal with the less expensive BSF larvae meal is a highly topical subject for the sustainable development of the aquaculture sector with several successful examples [ 18 , 19 , 20 , 21 , 22 ]. Moreover, dietary BSF has been shown to enhance gut health, gut microbiome, immunity and fish welfare at certain levels of inclusion [ 23 ].…”

Probiotic Bacteria in Gastro-Intestinal Tract of Hybrid Catfish Fed Insect Protein Meal

“…The cost of fish production has increased astronomically due to the cost of fishmeal which is the major protein source, thereby making fish culture business more tedious with little profit or sometimes losses. In order to reduce the pressure on the use of fish as a protein source in catfish diet; studies have been advocating for the use of supplementary feed with insect protein having more comparative advantage [5][6][7][8].…”
