Interpretive Summary:

Technical Abstract: Water stability of aquatic crustacean feeds, which must remain water stable for several hours, is important. The purpose of this study is to improve structural integrity of shrimp feed to minimize feed degradation and loss of nutrient in water by using plant biomass. Novel feed binders from various biomass were developed to improve water stability of the compound feed. Eight agricultural-based (cottonseed fiber (CSF), wheat straw (WS), peanut hull fiber (PF), distiller’s dried gain with solubles (DDGS), hemp fiber(HF), miscanthus (MS), sugar beet (SB), and soyhull (SH)), and two woody-based (softwood and hardwood) biomass feedstocks were evaluated as binding agent (0.5%) against four natural control binders (carboxymethyl cellulose (CMC), corn starch (CS), alginate (ALG) and wheat gluten (WG)) with respect to water stability, water absorption values, and nutrient leaching after being immersed in water up to 24 hours at 30 °C. All the diets with novel lignocellulosic based binders had significantly improved pellet water stability compared to the control diets with CMC, ALG and CS. Diets with CSF and DDGS had significantly improved pellet water stability compared to the diets with control binders (WG, CMC, ALG, and CS) after being immersed in water for 2h and 6h. CMC had the worst performance, followed by ALG in all time periods. Water absorption of pellets with the lignocellulosic micro-fibrillated fiber binders seems to be negatively correlated with water stability of pellets. The binder that best retained crude protein and ash in all time periods was DDGS, followed by PF and CSF. Lipid retention was the highest in pellets with HF, DDGS or PF binders. Regarding water stability and nutrient (protein, lipid, and ash) retention, DDGS, PF, CSF, MS, HF, and WS were ranked as the highest bindings. These can be produced easily and are less expensive natural alternatives to conventional binders.
