This study was designed to assess the suitability of using sweet potato leaf meal (SPLM) as a substitute for the complete or partial replacement of soya beans as protein source in fish feed formulation. One hundred and sixty Clarias gariepinus fingerlings were fed different levels of experimental diets containing 40% crudeprotein. Sweet potato leaf mealwas used at different levels of10% (Diet/Treatment 2 i.e. T2), 20% (T3) and 30% (T4), while 0% served as control (T1). Fingerlings were fed diet at 5% of their body weight for 42days. This study determined the growth, survival and the best inclusion rate of SPLM in the diet which was conducted in a plastic tank. All experimental diet were accepted by the Clarias gariepinus fingerlings without impairing growth. The highest mean weight gain (2.5+ 0.09g) was obtained in fish fed with 10% SPLM inclusion (T2), while the least (1.8+ 0.09g) was recorded in T4 i.e. 30% inclusion. Similar trend was obtained for length increase, protein efficiency and percentage survival. All fish were good in condition except those offered diet T4. The best SPLM inclusion level of the study was obtained in T2.

Abstract Fish bone is a solid waste that usually found in traditional fish markets of Ternate. The bone fraction contains high minerals such as calcium, phosphorus, and collagen proteins which are important for fish growth. Tuna fish bone waste was processed into dry fish feed and mixed into feed formulation of Tilapia. Four different dose of tuna fish bone powder were applied namely 0%, 1%, 3%, and 5% as mentioned treatment A, B, C, and D. Fish diet were given to Tilapia juvenile for 42 days. Results show that the body weight and specific growth rate are highest in fish which given 3% dose of tuna fish bone than other treatments. It reaches 38.66 g and 9.617% BW/day. The lowest FCR is 1.34 in treatment C and the survival rate is not significantly different among treatments (p>0.05).

This study integrates mathematical model in the plan of producing a fish feed formulation by reducing the total cost without neglecting the nutrient requirements. This study focuses on producing the perfect combination of fish feed for Mystus nemurus sp. catfish in different stages of life. The mathematical model developed will consider their required nutrients in each stage, the cost of each ingredient and the amount of nutrients to be consumed (nutrient composition of fish feed ingredients). This research employs AIMMS mathematical software to assist with the computation. The results from this study obtain a much better combination of different ingredients compared to available commercial pellets in terms of nutrient composition and production cost. The combinations yield much cheaper costs yet boosts up the nutrient consumptions, which is an eye-opener for independent local fish farmers. Thorough discussion on utilizing the results with future research directions will also be included.

The need to enhance the quality of fish feed produced in Nigeria was the major consideration in the design and development of a preconditioning system. The machine consists of two insulated cylindrical barrels, set of arranged paddles on a shaft, frame, hot water and feed mash inlet, discharge chute, chain and sprocket. It was powered by a three-phase 15 hp electric motor which transmits power to the machines shaft and set of paddles via chain and sprocket. The performance characteristics of the machine; mixing efficiency and throughput capacity were evaluated using Nigerian Institute for Oceanography and Marine Research (NIOMR) feed formulation at feed mash particle sizes of 900 µm, 550 µm, 520 µm and paired paddle rotating speed of the lower and upper chamber at (96.8; 145.2), (122.6; 183.2) and (174.5; 260.8) rpm respectively. The throughput capacity of the preconditioner is 650 kg/hr. The results showed increase in temperature and moisture content level of the particles as the machine speed decreases. The optimum mixing efficiency that gave best uniformity of mix was attained when Paired paddle speeds were (96.8; 145.2), (122.6; 183.2) with an average Biot numbers of 0.1.

AbstractThe effect of dietary digestible protein (DP) and/or digestible energy (DE) levels on lysine (Lys) requirements, Lys utilisation efficiency and voluntary feed intake (VFI) were studied in rainbow trout fry when Lys was the first limiting indispensable amino acid or in excess in the diet. Two trials were conducted at 11·6°C with eighty-one experimental diets, containing 280 g DP/kg DM (low protein (LP), trial 1), 600 g DP/kg DM (high protein (HP), trial 1) or 440 g DP/kg DM (medium protein (MP), trial 2), 17 MJ DE/kg (low energy (LE)), 19·5 MJ DE/kg (medium energy (ME)) or 22 MJ DE/kg (high energy (HE)), and nine Lys levels from deeply deficient to large excess (2·3–36 g/kg DM). Each diet was given to apparent satiety to one group of fifty fry (initial body weight 0·85 g) for 24 (MP diets, trial 2) or 30 (LP and HP diets, trial 1) feeding days. Based on N gain data fitted with the broken-line model, the relative Lys requirement was significantly different with the dietary DP level, from 13·3–15·7 to 22·9–26·5 g/kg DM for LP and HP diets, respectively, but did not significantly change with the DE level for a same protein level. The Lys utilisation efficiency for protein growth above maintenance was constant across diets, suggesting no effect of either dietary DE or DP levels. In Lys excess, the VFI was markedly decreased by the DP level but not by the extra DE supply. Our results suggest that the relative Lys need is best expressed in terms of percentage of protein content for optimum fish feed formulation, at least in rainbow trout fry.

This study investigated the content of selected minerals (P, Ca, K, Na, Mg, Fe and I) in local feed ingredients used by tilapia fish farmers in Tanzania. Analyses were performed on 26 local feed ingredients collected at four different geographical locations in Tanzania (Dar es Salaam, Morogoro, Mbeya and Mwanza). The samples were taken randomly from fish farmers, fish feed producers, fingerling producers and animal feed shops or centers near fish farms in each region. The results showed a wide range of mineral concentrations. The highest levels of P was found in fish skeletons (17.8 g kg-1), of Ca in limestone (107.3 g kg-1), of K in gallant soldier (51.0 g kg-1), of Na in marine shrimp (Exhippolysmata oplophoroides) (11.7 g kg-1), of Mg in prawn head waste (4.2 g kg-1), of Fe in azolla (2355 mg kg-1) and of I in full fat soybean (447 mg kg-1). The data on mineral content in feed ingredients can be used as a platform for better-targeted feed formulation for tilapia farming systems. In conclusion, the data suggest that if more than two ingredients are used in the diet, this may be sufficient to meet the mineral requirements of all cultured tilapia species and their hybrids, without inclusion of any mineral premix.

This research evaluates the effect of feed formulation on fish feed properties with the aim of providing information on its water absorption and physical properties of the feed. The main objective of the study is to analysis the effects of the 3 tuber crops (dried cassava, potato and cocoyam flour) on the floatability of fish feed. The fish feed ingredients with varying percentage (40, 70 and 100) of starch from cassava, potato and cocoyam were extruded using a single screw extruder with constant screw speed (285 rpm). The resulting extrudates were subjected to extensive analysis of physical properties, which included moisture content, mass, surface area, volume unit density, bulk density and porosity. The water absorption properties include, the relative absorption rate (%), the water stability (%), the expansion ratio (%) and the floating ability rate (%) were also determined. There was a linear increment between the increase in starch with floatability and water absorption properties of cassava and cocoyam starch; however, a nonlinear decrease relationship existed in percentages (%) of potato starch. The formulation with 40% cocoyam has the highest floatability while the least floatability was observed from 100% potato at first 10 mins of observation. At 40% starches, 76.66% of cassava, 66.66% of potato and 100% of cocoyam afloat for the period of observation (10-120 mins). In conclusion, the formulation with 40% cocoyam was adjudged as the preferable feed composition based on its floatability. From the result, it can be recommended that cocoyam starch support the floatability of fish feed.
