“…Azolla contains a high protein concentration, ranging from 25% to 35% of its dry weight [28,29]. Furthermore, Azolla contains EAAs such as lysine, methionine, cystine, threonine, tryptophan, arginine, isoleucine, leucine, phenylalanine, tyrosine, glycine, serine, and valine [30,31], which are higher than soybean meal except for histidine [32]. Azolla is also rich in minerals such as calcium, phosphorus, potassium, zinc, cobalt, chromium, boron, nickel, lead, cadmium, iron, manganese, and copper.…”

The aquaculture industry’s insatiable demand for fishmeal has led to a price surge, prompting the search for a sustainable alternative protein source. Enter Azolla meal, a plant protein that could be a viable substitute for fishmeal. This cost-effective supplemental feed could be a game-changer for small-scale producers looking to expand their aquaculture production. Numerous experiments have been conducted on replacing fishmeals with Azolla meals in fish diets, and the results have sparked further research. This review delves into Azolla’s composition, comparing it to fishmeal in terms of proteins, amino acids, fatty acids, vitamins, and minerals. It also explores the value of employing Azolla in fish feeds and the various methods to mitigate its adverse effects through feed additives during the feed formulation. This review discusses the essential effects of Azolla meal on the growth of various fish species, including tilapia (Oreochromis niloticus), catfish (Clarias batrachus), thai silver barb (Barbonymus gonionotus), common carp (Cyprinus carpio), rohu (Labeo rohita), and catla (Catla catla) and mrigal (Cirrhinus cirrhosus). Azolla’s potential extends beyond its use as a fish feed ingredient. It could also be utilized for bioremediation to remediate hazardous chemicals in water resulting from aquaculture, industrial, and household waste. Further research is needed to optimize the use of Azolla meal in fish feed and to develop cost-effective production methods. This review is a valuable resource for farmers looking to maximize profit when using Azolla in aquafeed and potentially sustainably enhance aquaculture production. With its promising potential, the Azolla meal could be the key to meeting the growing demand for fishmeals while reducing the industry’s environmental impact.

ObjectiveWe sought to assess the efficacy of feeding tocotrienol, a member of the vitamin E family, as it impacts physiological functions in fingerling fish.MethodsFingerling Largemouth Bass Micropterus nigricans with an initial mean body weight (±SD) of 0.98 ± 0.09 g were fed five diets containing tocotrienol at 0, 10, 20, 30, and 40 mg/kg (T0, T10, T20, T30, and T40 diets, respectively) for 42 days. After the feeding experiment, fish were challenged with Largemouth Bass ranavirus (LMBV) and monitored for 48 h.ResultFindings indicated a positive impact of tocotrienol‐supplemented diets on fingerling survival. Furthermore, the weight gain and specific growth rate of fish that received the T30 and T40 diets were significantly higher than those of fish that were fed the T0 diet. Tocotrienol supplementation improved the protein efficiency ratio and condition factor and increased the whole‐body lipid and protein content. Conversely, the hepatosomatic index, viscerosomatic index, and feed conversion ratio were significantly decreased by tocotrienol supplementation. Fish that were fed the T30 and T40 diets exhibited significantly higher hepatopancreas lipase activity and intestinal protease activity. Generally, superoxide dismutase and catalase activities in the liver increased as the tocotrienol level increased. Additionally, the liver malondialdehyde concentration decreased, and there was an improvement in the structure of liver cell tissue. Survival at 48 h after the LMBV challenge was significantly higher in fish that were fed the T30 and T40 diets compared to fish that were given the T0 diet. Maximum specific growth rate was observed at a tocotrienol concentration of 33.63 mg/kg.ConclusionResults suggest that supplementation of Largemouth Bass fingerling diets with appropriate quantities of tocotrienol can enhance survival, growth, antioxidant capacity, digestion, and uptake of nutrients as well as disease resistance.
