Table 2.

Growth parameters (K, FCR, SGR (%)), feed quantity provided and mortality during the experimental period for the two diet groups (conventional vs. low marine protein; n = 3 cages per diet group).

Diet	K	FCR			SGR (%/day)			Mortality (n)	Mortality (%)
		T1–T2	T1–T3	T1–T4	T1–T2	T1–T3	T1–T4	T1–T4	T1–T4
Conventional diet	1.74 ± 0.01	2.03 ± 0.19	1.87 ± 0.03	2.06 ± 0.09	1.39 ± 0.04	0.74 ± 0.00	0.69 ± 0.01a	483 ± 29	22.03 ± 1.30
Low marine protein diet	1.76 ± 0.02	2.08 ± 0.24	1.84 ± 0.2	1.98 ± 0.17	1.35 ± 0.06	0.73 ± 0.02	0.67 ± 0.01b	457 ± 85	20.87 ± 3.97

Different letters in the same column indicate significant different values between diet groups (T-test; p < 0.05).
