“…Lysine serves as a key substance, playing important roles in the body, such as regulation of the carnitine synthesis responsible for the transportation of long chain fatty acids into the mitochondria [53] and osmoregulation [54]. Lysine is also involved in maintaining the acid-base balance, nitrogen retention in the tissue [55], reducing the fat levels of the body, and increasing muscle growth in fish by rapidly increasing the size and length of muscle fibers [56] and eventually increasing weight gain [57]. Besides reduced growth and feed efficiency, dorsal and caudal fin erosion is also a consequences of lysine deficiency in rainbow trout [58].…”

Evaluation of Filamentous Fungal Biomass Cultivated on Vinasse as an Alternative Nutrient Source of Fish Feed: Protein, Lipid, and Mineral Composition

The rapid growth of aquaculture and scarcity of conventional fish feed supplements has prompted the introduction of new sustainable supplementation sources. In this study, the potential of five strains of fungal biomass of Ascomycetes and Zygomycetes edible filamentous fungi, Aspergillus oryzae, Neurospora intermedia, Rizhopus oryzae, Monascus purpureus, and Fusarium venenatum, cultivated on vinasse, a by-product of the bioethanol industry, as alternative protein sources for fishmeal in the fish diet was evaluated. It was observed that 5% vinasse with an initial pH of 5–6.5 can support fungal biomass yields of 34.3 ± 2.4–118.5 ± 3.9 g DM/L for A. Oryzae, N. intermedia, and R. oryzae. High protein contents of about 44.7%, 57.6%, and 50.9% (w/w), and fat contents of 7.0%, 3.5%, and 5.5% (w/w) were obtained for A. oryzae, N. intermedia, and R. oryzae, respectively. The latter three fungi species contained noticeable amino acid contents, including promising profiles of amino acids that are highly compatible with those of fishmeal. These findings provide evidence that fungal biomasses, with their relatively high protein content, good amino acid profiles, and other essential nutrients, are a promising supplementation alternative that can be produced from low-value by-products and organic-rich waste streams like vinasse to meet the dietary protein requirements in fish feed.

“…Earthworms can serve as animal feed, especially for fish and poultry (Edwards and Niederer, 2011; Hamid et al, 2016). Earthworms with a high content of phosphorus found in our experiment could be used in feed mixtures for animals as a substitute for phosphate rocks that are gradually depleting (Tarayre et al, 2016).…”

Dynamics of a vertical-flow windrow vermicomposting system

Large-scale vermicomposting under outdoor conditions may differ from small-scale procedures in the laboratory. The present study evaluated changes in selected properties of a large-scale vertical-flow windrow vermicomposting system with continuous feeding with household biowaste. The windrow profile was divided into five layers of differing thickness and age after more than 12 months of vermicomposting. The top layer (0-30 cm, age <3 months) was characterised by partially decomposed organic matter with a high pH value and an elevated carbon/nitrogen (C/N) ratio. The earthworm biomass was 15 g kg with a population density of 125 earthworms per kilogram predominantly found in clusters. The greatest amount of fungi (3.5 µg g dw) and bacteria (62 µg g dw) (expressed as phospholipid fatty acid analysis) was found in this layer. Thus, the top layer could be used for an additional cycle of windrow vermicomposting and for the preparation of aqueous extracts to protect plants against diseases. The lower layers (graduated by 30 cm and by 3 months of age) were mature as reflected by the low content of ammonia nitrogen, ratio of ammonia to nitrate nitrogen and dissolved organic carbon, and high ion-exchange capacity and its ratio to carbon. These layers were characterised by elevated values for electrical conductivity, total content of nutrients, available magnesium content, and a relatively large bacterial/fungal ratio. On the basis of the observed properties, the bottom layers were predetermined as effective fertilisers.

“…Earlier studies designed to elucidate the effect of betaine were carried out in common carp [41], blunt snout bream [42], juvenile grouper [43] and pike perch [44]. Similarly, the effect of lysine on growth performance was investigated by several researchers in fishes such as African catfish [26], bream abramis [45] and sea bass [46]. However, the effect of betaine on the expression of endocrine marker genes was not studied earlier.…”

“…Dietary ration, dietary protein content, and body growth rate in many fish species is positively correlated with blood levels of IGF-I or tissue levels of its mRNA [25]. Supplementation of fish feeds with lysine and betaine enhances protein deposition in the body [26,27] and associated with nitrogen retention [28]. Thus, a research study was carried to see the effect of lysine and betaine on feeding and growth related gene responses in L. rohita.…”
