<p>Edible films is a thin layer that can be eaten directly with the food it is coated with and is biodegradable, so it is used as an alternative to plastic packaging. The components of the edible film consist of hydrocolloids (proteins and polysaccharides), lipids (fatty acids), and composites (a combination of hydrocolloids and lipids). The physical characteristics of edible films that are commonly used are thickness, tensile strength, elongation percentage, water vapor transmission rate and solubility. Several studies have shown that the addition of beeswax to gelatin and nanochitosan edible films can produce films with good physical characteristics. The addition of a greater concentration of beeswax can increase the thickness value and decrease the value of the water vapor transmission rate and water solubility of the edible film.</p>

<p>Pangasius fillets have a shelf life of 6 days at cold temperatures because fish is a perishable food. Application of biocomposite edible films made from gelatin, nanochitosan, and beeswax can extend the shelf life of pangasius fillets due to their ability to improve mechanical and physical properties which will affect the product. The effect of using biocomposite edible films on pangasius fillets can be analyzed through pH, ​​organoleptic, and rottenness parameters.</p>

<p>Mahseer aquaculture activities are still relatively low because they are constrained by slow growth. Potassium diformate can promote growth by improving digestion. This research aimed to determine the optimum dose of potassium diformate addition to artificial feed for the best growth rate in mahseer fingerlings. The research was conducted from July – August 2022, in hatchery of the Faculty of Fisheries and Marine Sciences, Padjadjaran University, West Java, Indonesia. The method used in this research was experimental, using a completely randomized design (CRD) consisting of four treatments and five replications. The test fish used were 200 mahseer fingerlings measuring 4.5 – 5.0 cm. The treatment used was the addition of potassium formate to artificial feed at a dose of 0% (A), 0.1% (B), 0.3% (C), and 0.5% (D). The length of maintenance is 40 days, with the amount of feeding 3% of the fish's body weight. Parameters observed included&nbsp;specific growth rate<em>&nbsp;</em>(SGR), feed conversion ratio (FCR), survival rate (SR), and water quality (dissolved oxygen, temperature, pH). The research results showed that the addition of 0.3% potassium diformate gave the best results with the highest SGR value of 0.75%, FCR of 3.80, EP of 26.87%, SR of 100%. It can be concluded that the addition of potassium difomate has a good effect on the growth of mahseer fingerlings if given at optimal doses.</p>

<p><strong>Aims:</strong> This study was conducted to evaluate the effects of dietary inclusion of the bark of <em>Afrostyrax lepidophyllus </em>on growth and body composition of <em>Clarias gariepinus</em>.</p> <p><strong>Study Design:</strong> This study was carried out from April to May 2022 in the Agro-ecological Farm of Bilone at Obala Lekié Division, Center Region of Cameroon.</p> <p><strong>Methodology:</strong> Juvenile weighing 9.29 ± 0.15 g were divided into four triplicate treatments before being fed with diets containing 0 g (T₀ or control), 1 g (T₁), 1.5 g (T₂) and 2 g (T₃) <em>A. lepidophyllus </em>diet for 56 days. Fishes were fed at the rate of 5% body weight and every 14 days, intermediate sampling was done during which juveniles per treatment were counted, measurements were taken on a representative sample and the feeding rate was adjusted. The main water parameters were recorded daily before feeding.</p> <p><strong>Results:</strong> Adding the bark of <em>A. lepidophyllus </em>in the diet significantly enhanced growth, feed nutrients utilization and body composition of juvenile<em> C. gariepinus</em> independent of the inclusion level. Fish fed T₃ diet recorded final weight, weight gain (WG), feed conversion ratio (FCR) and protein efficiency ratio (PER) significantly high (<em>P</em> &lt; 0.05) to those recorded in fish fed with the control diet. The same trend was observed with macro-nutrient retention as compared to the control.</p> <p><strong>Conclusion:</strong> This study clearly showed that dietary inclusion of the bark of<em> A. lepidophyllus</em> powder improves growth performances, feed nutrients utilization and body composition of juveniles<em> C. gariepinus</em>.</p>
