TABLE 5.

Estimation of acetate uptake in hindgut sections of the fish species

Species	Weight range (g)a	Gut section	Weight range of gut section (g)a	Acetate turnover (nmol ml−1 min−1)b	Rate of absorption (mmol day−1)c	Acetate available for energy (mmol day−1 kg−1)
K. sydneyanus	2,050-4,200	IV	78-160	570	64-131	32
		V	117-238	448	75-153	37
O. pullus	800-1,500	IV	11-21	551	9-17	11
		V	11-21	373	6-11	7
A. arctidens	741-2,880	IV	10-37	312	5-17	7
		V	10-37	130	2-7	3

^an = 16 (K. sydneyanus), 43 (O. pullus), or 38 (A. arctidens).

^bValues are means of turnovers determined for the relevant gut sections in Table 3.

^cDetermined from gut weight × turnover rate, in which the assumption is that 1 g of weight of gut is equivalent to 1 cm³.
