Fish feed delivery is one of the challenges which fish farmers encounter daily. The main aim of the feeding process is to ensure that every fish is provided with sufficient feed to maintain desired growth rates. The properties of fish feed pellet, such as water stability, degree of swelling or floating time, are critical traits impacting feed delivery. Some considerable effort is currently being made with regard to the replacement of fish meal and fish oil with other sustainable alternative raw materials (i.e., plant or insect-based) with different properties. The main aim of this study is to investigate the motion and residence time distribution (RTD) of two types of solid feed pellets with different properties in a cylindrical fish tank. After experimental identification of material and geometrical properties of both types of pellets, a detailed 3D computational fluid dynamics (CFD) study for each type of pellets is performed. The mean residence time of pellets injected at the surface of the fish tank can differ by up to 75% depending on the position of the injection. The smallest residence time is when the position is located at the center of the liquid surface (17 s); the largest is near the edge of the tank (75 s). The maximum difference between the two studied types of pellets is 25% and it increases with positions closer to the center of the tank. The maximum difference for positions along the perimeter at 3/4 tank radius is 8%; the largest residence times are observed at the opposite side of the water inlet. Based on this study, we argue that the suitability of different solid feed pellets for aquaculture systems with specific fish can be determined, and eventually the pellet composition (formula) as well as the injection position can be optimized.

Sukamaju Village that is located in the Sail Sub Regency, Pekanbaru is potential for developing fish culture. The knowedge of the community in fish culturing method, however, is relatively low and to improve it,  a socialization program has been conducted in July-September 2020. The community was trained to culture fish and fed the fish with  turmeric enriched pellets through mentorial and practice in fish feed pellet manufacture and fish rearing. The progress was monitored weekly and evaluated by the 8th week.  Results shown that the community was able  make fish feed pellets and also able to culture the fish. The result of monitoring and evaluation shown that the fish farmer in Sukamaju Village is commited to develop the turmeric enriched fish fed pellet processing as the effort of program sustanability.

The objective of this study was to evaluate the floating and stability of fish feed pellets formulated with different concentration of Baobab (Adansonia digitata) leaf meal (BLM). Five isonitrogenous fish feed (35% CP) with varying inclusion levels of Baobab leaf meal (0% BLM, 4% BLM, 8% BLM, 12% BLM and 16% BLM designated as D1, D2, D3, D4 and D5 respectively was used. Ten (10) pellets of each experimental feed were placed in plastic beaker (55 x 25 x 30 cm) for 50 minutes. Feed pellet floatability and stability were recorded every five minutes. Results showed that feed pellet floatability increased significantly (P<0.05) with increase in BLM concentration. Highest feed pellet floatability (41.66 ± 2.88 minutes) was recorded in D5 (16% BLM) and least (0.00 ± 0.00 minutes) in D1 (0% BLM) which sank down immediately. Similarly, feed pellet stability increased significantly (P<0.05) with increase in BLM concentration. Highest pellet stability (42.66 ± 1.17 minutes) was recorded for D5 (16% BLM) and least (18.54 ± 2.10 minutes) in D1 (0% BLM). Based on these findings, it is concluded that 16% BLM inclusion level in fish feed has led to a high pellet floatability and stability. Therefore, Baobab leaf meal (BLM) which is relatively cheap, toxic free, easy to process and available specifically in Northern part of Nigeria is recommended for floating feed formulation.
