This is possibly better giving all the info as per Steve's layout on each fish in alphabetical order:

Sorry Steve - age is catching up on me in doing a writeup on each (Don't tell Stu tho)

Here is a link that is useful for fish species: http://nswaqua.com.au/info.html and has other helpful info |

Common names: Sleepy Cod Scientific name: Oxyeleotris lineolatus Herbivore/Carnivore/Omnivore: Carnivore in the wild, but can be converted to sinking pellets in captivity Optimum temperature for growth: Some say >22C, others say >26C Tolerated temperature: Anything above 18C. Should not be handled below 18C but will survive. Major problems if below 14C. Optimum DO mg/L: Dont know, but what does that matter if you havent got a DO meter? Tolerated DO mg/L: Can be stocked at high density provded you have enough DO Optimum PH: 7.0-7.5 Tolerated PH: Dont know Breeds in captivity without extraordinary means: It sounds like it's possible but I dont know if anyone is doing it. Female spawn every 2 weeks when above 26C. Other notes: Excellent eating Do not require purging Placid, can be handled Tollerant of high density stocking Grow faster in tanks compared with ponds Sounds like they would be easier to grow than Murray Cod (not that I've tried, hell I havent even got a fisk tank) _________________ |

mainly from http://www.dpi.vic.gov.au/DPI/nrenfaq.n ... A7591?open Common names: Eel, Short-finned Eel, Long-Finned Eel Scientific name: Anguilla australis (Shortfin) Anguilla reinhardtii (Longfin Herbivore/Carnivore/Omnivore: Carnivore Optimum temperature for growth: cool (specifics ??) Tolerated temperature: cool to warm (specifics ??) Optimum DO mg/L: ?? Tolerated DO mg/L: will tolerate low DO?? Optimum PH: ?? Tolerated PH: will tolerate a large range Breeds in captivity without extraordinary means: No Other notes: Eels are extraordinarily tough fish which will tolerate an incredible range of water chemistry and temperatures as well as very high stocking densities (up to 100kg/m3), you will have to try hard to kill these. Is has so far proved impossible to breed eels in captivity due to the highly complex breeding cycle, but wild caught fingerlings (up to 300g) can be bought relatively cheaply, and can reach 1kg within a year. See http://nswaqua.com.au/InfoLinks/Eels.htm http://www.nativefish.asn.au/ http://www.dpi.vic.gov.au/DPI/nrenfaq.n ... enDocument Common names: Murray Cod, Cod, codfish, goodoo, greenfish, Murray perch Scientific name: Maccullochella peelii peelii Herbivore/Carnivore/Omnivore: Carnivore Optimum temperature for growth: 20-25 Tolerated temperature: 9-34 Optimum DO mg/L: >5.0ppm Tolerated DO mg/L: 4.0ppm Optimum PH: 6.5-8.0 Tolerated PH: 5.5-? Breeds in captivity without extraordinary means: Yes Other notes: Fantastic FCR and growth rates, very good eating, do not need flushing if kept in relatively clean water, stock available, can go from fingerling to 600g in 6-7 months in a well maintained aquaponics system. High stocking densities recommended to control territorial/cannibalistic behaviour See- http://www.dpi.vic.gov.au/DPI/nrenfaq.n ... enDocument http://www.nativefish.asn.au/cod.html Asian Market Taste Test Report- http://www.dpi.vic.gov.au/DPI/nrenfaq.n ... enDocument |

Common names: Barramundi Scientific name: Lates calcarifer Herbivore/Carnivore/Omnivore: Carnivore Optimum temperature for growth: 28.5 Tolerated temperature: Officially 20 - 38, but I have had them alive and still eating (mind you sluggishly) as low as 16.2 
Optimum DO mg/L: 11 Tolerated DO mg/L: 6 - 12 Optimum PH: 7 Tolerated PH: 6.5 - 8 Breeds in captivity without extraordinary means: nope. All boys until age of 5, then a salt water environment has to be created in order for the females to spawn. Don't ask me for details 
Other notes: Many people say they are hard to keep, but touch wood, mine are going well. They prefer higher densities. I believe it makes them less aggressive towards one another. They will eat their mates if left without food  Under 100 grams it is recommended to feed 4 times a day, after that twice a day. I feed mine twice, sometimes 3 times a day and they are always hungry The tank with more in it seems to create a competitive environment for food and they seem to eat more. I hope to have mine to plate size within 7 months, and am pumping the food into them while the weather is warm. Officially, they should go from 30mm to 300mm in 5 months. Others will tell you how dependant their growth rate is on water quality and temperature. The warmer it is, the more frenzied their feeding. So long as you can keep the water over 20 degs, and you have a stable system with nice clean water, I would suggest no inherent problems keeping barra as compared to any other species we have to choose from. All this is IHMO
