Abstract
This study was designed to assess the effect of incorporating graded levels of green macroalgae seaweed (Ulva sp.) into diets of juvenile dusky kob (Argyrosomus japonicus) on growth performance, hematology and serum biochemistry. Five experimental diets were formulated to contain 0 (Ulva0), 50 (Ulva50), 100 (Ulva100), 150 (Ulva150) and 200 (Ulva200) g seaweed meal/kg commercial kob feed on a dry matter basis. Seventy-seven dusky kob fingerlings (mean body mass 9.14â¯Â±â¯0.30â¯g) were distributed into each of 20 experimental tanks and offered diets at 2.8% body mass. Weight and length of fish were measured weekly for 9â¯weeks. At the end of the feeding trial, fis...
