A 12-week feeding trial was conducted to investigate the nutrient utilization, growth performance, and hematological indices of Cyprinus carpio var. communis fingerlings fed diets based on aquatic macrophyte, Ceratophyllum demersum as a replacement of fish meal (FM). Six isonitrogenous and isocaloric diets containing graded levels of C. demersum 0%, 5%, 10%, 15%, 20%, and 25%, respectively, as replacer of FM were formulated. Total of 360 fingerlings with an initial weight of 3.65 ± 0.98 g were randomly stocked in 70 L plastic tanks water volume 60 L connected with a continuous flow-through system (1–1.5 L/min) for each treatment and were run in triplicate having 20 fish in each tank. At the end of the feeding trial, it was observed that the C. carpio var. communis fingerlings receiving 5% and 10% C. demersum in the diet showed improvements in live weight gain (LWG), specific growth rate (SGR), feed conversion ratio (FCR), and protein efficiency rate (PER). While further addition of C. demersum as a replacement of FM from 15% to 25% led to the progressive decline in the values of LWG, SGR, FCR, and PER. Hematological data also exhibited a linear declining trend beyond the 10% C. demersum replacement level. The fish fed with higher inclusions of C. demersum in each diet significantly (P<0.05) affected whole body composition with the lowest protein and fat amounts recorded at higher replacement levels significantly (P<0.05). The highest protein and fat contents were observed at 5% and 10% diets. Except serum glucose, cholesterol, alanine aminotransferase (ALT), and aspartate aminotransferase (AST), the other serum indices exhibited a decreasing trend with increasing inclusion of C. demersum in the diet. The results of the present study clearly demonstrated that the inclusion of 10% C. demersum did not affect the growth and other parameters of C. carpio var. communis fingerlings compared to the 50% FM diet. However, it is recommended that 10% FM can be substituted without compromising the growth and nutritional quality of fish.

“…It also recommended that fermented water hyacinth to be used at levels greater than 30% as it influences fish growth at this level compared with low levels (<20%; Sadique et al 2018) and this treatment is not required at lower levels (<10%) of incorporation (El-Sayed 2003). Replacement of water hyacinth meal for 20% fishmeal in rohu diet achieved a higher weight gain than feeding up to 40% substitution level (Patel et al 2016). Eichhornia meal can be incorporated in the diet of L. rohita fingerlings at 15% level without having an adverse effect on the growth and dry matter of fish, and palatability of the feed (Debnath et al 2018).…”

Perspectives on utilization of macrophytes as feed ingredient for fish in future aquaculture

Aquaculture activity supplies high-quality protein at affordable cost. A global call for foods of aquatic origin has heightened not only due to the zooming population growth, but also because of a choice of healthier foods for human beings. As the industry expands, it is facing the high cost of feeding because the key ingredients, that is fishmeal and fish oil, of aquadiet are very expensive. Identification of alternate foodstuffs that will remarkably minimize the expense of productivity of animal protein becomes a priority with due regard to environmental footprint. Alternative feed components are vital in partially or completely substituting unsustainable but high-value components or constituents that will otherwise have direct competition with human use. Utilization of aquatic plants as a substitute for fish meal has the potential to revolutionize aquaculture in meeting global protein demand. A lot of money is spent on aquatic weed management, so this research idea tries to integrate both economic aspects and the environmental concerns. Macrophyte-based feed ingredients have promising nutrient profile: crude protein ranges between 11% and 32%; lipid, 2.90% and 16.81%; and ash, 8% and 31%, a good array of amino acids; and a good amount of micro-and macronutrients that make them prosperous substituents for fish feed.

The utility of macrophytes in freshwater aquaculture is diverse. We review the benefits of macrophytes in aquaculture into broadly three useful perspectives: (i) Feeding, (ii) Bioremediation, and (iii) Symbiosis. Macrophytes are used as direct food by herbivores for their potential nutrient values with a maximal protein content of 35% (D/W basis) and as ingredients for fish feed preparation with optimal 50% protein inclusion to reduce feed cost in commercial aquaculture. Macrophytes are used for wastewater treatments to eliminate contaminants, including As, Cu, Cd, Cr, Hg, and Pb, to 99.9%, and to reduce BOD (Biological Oxygen Demand) to improve water quality. Intake of remedied wastewater into aquaculture enhances water productivity through phytoplankton growth. An estimate is that 1.0 L of remedied wastewater, particularly sewage effluent adds an average of 0.05 g N & P and 0.99‐L freshwater into aquaculture to yield an average of 0.309 g fish. Macrophytes are integrated with fish in commercial aqua‐farming. Plants and fish are farmed together in aquaponics. They are used as substrates for some commercial fish species to lay eggs in farming. They are raised with ornamental fish for benefits in aquariums. Nevertheless, extensive studies are required to harness more benefits from macrophytes.
