The effect of temperature on survival, growth, feeding and metabolic activity of the southern rock lobster, Jasus edwardsii
This study investigated the effect of temperature (18, 20, 22 and 24°C) on growth, feeding and metabolism of post-puerulus lobsters as part of a larger study of the culture potential of farming the southern rock lobster, Jasus edwardsii.

Jasus edwardsii. There was no significant difference (
P>0.05) in the specific growth rates (SGR) at 18, 20 or 22°C; however, growth decreased significantly (
P<0.05) at 24°C. The growth response was described by a quadratic regression (SGR=−0.031
T
2+1.261
T−10.884,
r
2=0.77), which predicted the optimum temperature for growth to be 20.6°C. Lobsters held at 22°C had smaller intermoult periods than lobsters at 18°C; however, a decreased moult increment at 22°C meant that growth rate did not increase at that temperature. The decreased growth at 24°C compared to 22°C was evidenced by a longer intermoult period. Temperature affected survival of lobsters, with survival at 24°C being significantly lower (
P<0.05) than at 18°C. There were no significant differences (
P>0.05) in survival at 18, 20 or 22°C. The response of feed conversion ratio (FCR) to temperature was described by a quadratic regression (FCR=0.011
T
2−0.434
T+5.231,
r
2=0.995), which suggested that the optimum temperature for feed conversion was 19.3°C. Oxygen consumption rates (
M
O
2
) increased with increasing temperatures between 18°C and 22°C and declined at 24°C; whilst total ammonia nitrogen (TAN) excretion increased with increasing temperature. The relationships were described by regression equations:
M
O
2
=−0.044
T
2+1.91
T−18.553 (
r
2=1.0); TAN=0.127
T−1.174 (
r
2=0.91). A temperature of 24°C appears to be above the upper thermal tolerance of juvenile
J. edwardsii. Lobsters held at this temperature showed reduced survival (compared to those at 18°C), reduced growth (compared to those at 22°C) and appeared to be suffering from respiratory stress (moult-related mortalities, low
Q
10 between 22°C and 24°C). Overall, the results indicate that juvenile
J. edwardsii can be cultured at 22°C without adversely affecting their growth, survival or feed efficiency with optimal temperature range between 19 and 21°C.</description><identifier>ISSN: 0044-8486</identifier><identifier>EISSN: 1873-5622</identifier><identifier>DOI: 10.1016/S0044-8486(99)00341-5</identifier><identifier>CODEN: AQCLAL</identifier><language>eng</language><publisher>Amsterdam: Elsevier B.V</publisher><subject>Ammonia excretion ; Animal aquaculture ; Animal productions ; Aquaculture ; Biological and medical sciences ; Crustacea ; Feed conversion ratio ; Fundamental and applied biological sciences.
