Source and selection Buy fresh fish from reputable suppliers or harvest from clean waters. Inspect appearance: eyes should be clear and bulging, gills bright red or pink, flesh firm and resilient, and skin glossy. Avoid fish with strong ammonia or sour odors. If using frozen fish, ensure it was frozen promptly after harvest and kept at a constant temperature. depositphotos.com Clean handling and hygiene Wash hands thoroughly with soap and water before and after handling fish.

Keep processing areas shaded and, if possible, cooled. Work quickly to limit time at ambient temperature. Evisceration and washing Eviscerate (gut) fish as soon as possible after death...

Providing good fish feed in tilapia cultivation is essential for growth performance, feed conversion efficiency, fish health, and profitability. Good feed strategy covers feed composition, pellet quality, feeding rate and schedule, feed management practices, and monitoring. Below are key principles and actionable steps to provide high-quality feed for tilapia. tilapia (depositphotos.com) Feed formulation and nutrient composition Protein: Tilapia require diets with appropriate protein levels depending on life stage. Fry and fingerlings need higher protein (32–45%), grow-out tilapia typically need 25–35% protein. Use digestible protein sources such as fishmeal, soybean meal, and other plant or insect proteins balanced by amino acid profile. Energy: Provide sufficient energy (carbohydrates and lipids) to spare protein for growth. Lipids (4–8%) supply energy and essential fatty acids; vegetable oils are common. Amino acids: Ensure limiting amino acids (lysine, methionine) are present; supp...
