The proximate composition of S. dichotomus, namely,
protein, carbohydrates, lipid, energy content was equivalent
to that of Artemia sps. and had a low ash content as shown
Fig. 1. It is evident that goldfish, C. auratus
actively feed
on adult fairy shrimp; the biochemical analyses of the tissue
of C. auratus fed on S. dichotomus showed more carbohydrate
(1.3%) and lipid (1.7%) than fish fed on Artemia (Table
1). A significant difference (p < 0.01) existed between the
composition of the feed and the fish fed on different feed.
When comparing the length and weight, fish fed on Streptocephalus
sps. attained a growth of 34.8 ± 0.05 mm and a
weight gain of 3.00 ± 0.15 g, like that of fish fed on Artemia
sps. (length, 34.8 ± 0.02 cm; weight, 2.99 ± 0.10 g) after 21
days (n = 15; p > 0.5). The specific growth and relative
growth rates based on weight were as follows: for fish fed
