Ok this would be useful info for the wiki I know it here somewhere but what is the safe upper limit on temperature for silver perch and murray cod? When I get time I would be happy to up date the wiki. |

Silver Perch are from around 6 degrees c up to around 32 degrees c. Murrays would be similar, maybe not as cold. |

According to a chart I have published by Stuart Rowland the tolerance range for Silvers is 2 - 38C, optimum for growth 23 - 28C. Goldens 4 -38C, optimium 23 -28C, Barra 12-42C, optimum 27 -32C. He also states that temps reaching the upper and lower limits will kill fish if held there for extended periods. |

Thanks for the info my greenhouse smaller systems have reached 32c I have had to add cool water to them. It looks like I will have to transfer water from the larger system to balance them in hot weather. |

Just try and keep the water temps in that 23 - 28 range for as long as you can if you are hoping to harvest in around 2 years time. Apparently growth is not that great in temps over 30. |
