Identification of feed enhancers for juvenile largemouth bass Micropterus salmoides

The effects of increased temperature and CO2 on the Amazon fish, tambaqui (Collosoma macropomum, Cuvier, 1818)

“…The similarity of the Tambaqui physiological profile on all three treatments reflects a satisfactory rearing environment. Similar productive performances in pond systems were obtained by Kubitza et al [22] with Micropterus salmoides and Affonso et al, [9] with Tambaqui in pond culture and Good et al [23] with O. mykiss.…”

Effect of several feeding stimulants on diet preference by juvenile gibel carp (Carassius auratus gibelio), fed diets with or without partial replacement of fish meal by meat and bone meal

“…Ž . without major adverse effects on growth Prendergast et al, 1994. Kubitza et al 1997 also reported that inosine-5 X -monophosphate had a high feed-enhancing effect in largemouth bass when added to a soybean-based diet.…”

Effects of betaine on the growth of the fish piauçu, Leporinus macrocephalus

“…Betaine, a common feed attractant, has been used as feed enhancer in fish, as reported for coho salmon Oncorhynchus kisutch (Castro et al, 1998), winter flounder Pleuronectes americanus (Melanie et al, 2000) and gibel carp Carassius auratus (Xue and Cui, 2001); it has also been mixed with other compounds for reaching this growth-stimulating effect, as reported for largemouth bass Micropterus salmoides (Kubitza et al, 1997), and striped bass Morone saxatilis (Papatryphon and Soares Jr., 2000a and b). In fact, several investigations have reported that betaine improved growth in fish (Clarke et al, 1994;Virtanen et al, 1994;Castro et al, 1998;Melanie et al, 2000;Beklevik and Polat, 2001).…”
