Abstract
The present study aimed to compare the nutritional effects of a mixture of phytoplankton and zooplankton and a formulated pelleted feed on the growth, survival, moulting, immune and organosomatic indices of juvenile marron ( Cherax cainii Austin, 2002) cultured for 90 days, under controlled laboratory conditions.
1. Introduction
Freshwater crayfish farming is well established worldwide particularly in Europe, and the United States, with the industry still under development in Australia ( Hollows, 2016 ). The global freshwater crayfish production for the year 2019 was 2,162,159 tonnes ( FAO, 2021 ).
2. Materials and methods
Plankton and experimental animals were collected from a semi-intensive commercial marron farm in Manjimup (34°18′75″ S, 116°06′61″ E), Western Australia. Pond water was filtered separately using plankton net for phytoplankton and zooplankton to obtain the total concentrated quantity of 15 L of sub-sample for phytoplankton and zooplankton each.
3. Results
All the water quality parameters were maintained in an optimum range for marron growth and survival ( Fotedar et al., 1999; Morrissy et al., 1984, 1990; Policy, 2003; Villarreal, Peláez, 1999) ( Table 2 ).
4. Discussion
At the end of this study, live plankton mixture significantly improved the SGR and WG % of marron, similar result of improved SGR were observed in yabbies fed with zooplankton ( Austin et al., 1997; Jones et al., 1995; Verhoef et al., 1998 ).
5. Conclusion
In this study, it was possible to maintain a constant plankton density, as the experiment was conducted under controlled laboratory conditions. While recreating the experiment under outdoor conditions the environmental parameters should be considered.

How to farm marron?
Firstly, without any great expense and worrying commitment, an agricultural farmer can diversify by cropping small numbers of marron from existing farm dams. Or, secondly, by building many specially designed and equipped marron ponds at a favourable location and managing the farm intensively to give large harvests of marron. Marron as a Hobby Intensive commercial production of marron must be clearly distinguished from hobby marron in the farm dam. Intensive production is best sited in the extreme Southwest, although marron will grow in most farm dams. In farm dams, marron can grow to legal size within 15 months, but their growth is limited by the amount of food available, numbers of marron in the dam, and water temperatures. Preferably the dam selected should contain at least 1.5 metres of water at the end of summer. The water should be turbid or milky, and not clear. Turbid water gives protection from cormorants and summer heating. Ideally the salt content should be less than 1 000 mg per litre to promote clay turbidity. Avoid dams which have heavy, green algal blooms, as overnight, blooms of algae may develop and cause oxygen deficiencies. The bottom of the dam should not have a build-up of manure and pasture debris. This build up also may cause severe oxygen problems. The dam selected should contain no koonacs, yabbies or redfin perch.

How to feed a martin?
into the air cues the martins to go after the food, so this is usually the best way to begin supplemental feeding. Food can be tossed into the air by hand, or with a slingshot, plastic spoon, or blowgun; it helps if the food is tossed as high as, or slightly above, the martin housing. Try tossing food when the martins are sitting out on perches or porches; toss it so it arcs up into the air a few feet in front of them. Many wasted shots may hit the ground before the martins begin to take the airborne food, so be ready to give the martins a chance to catch on before giving up. If they refuse to chase the food, they may not be hungry yet.
What do Martins eat?
Martins feed only on flying insects, so they need to be “trained” to recognize crickets, mealworms, and cooked egg as food when weather is not conducive to foraging. Tossing or propelling food items once the martins have already learned to accept tossed food. Martins may have a difficult time recognizing items offered on trays or inside houses or gourds as food unless they have already learned that these items are food through active (tossed) feeding. However, some landlords have reported success with in-house feeding, so it’s worth trying. As with active feeding, it can take martins several days to catch on, so landlords may want to start stationary feeding at the onset of poor weather, by providing some items in a feeder while also tossing food.
Who was the first landlord to feed martins?
Many individuals have contributed to theideas presently used in offering supplemental food to weather-stressed Purple Martins. One of the first landlords to feed martins from a platform was Ed Donath of Ar-lington Heights, IL. Ed also was one of the first to use cooked eggs as a food. Ed’s recipe has been tweaked by Ohio landlords Dan & Sherri Bacak, and Michigan landlord Mary Dawson. Bruce Meyer of Wichita, Kansas was the first land-lord we know of to train his martins to accept mealworms as food by using a slingshot to hurl them into the air.
