Aquaculture
Fresh Water Species
Commonly raised species in freshwater ponds are the carps, tilapia, catfish, snakehead, eel, trout, goldfish, gouramy, trout, pike, tench, salmonids, palaemonids, and the giant freshwater prawn Macrobrachium. In brackishwater ponds, common species include milkfish, mullet and the different penaeid shrimps Penaeus
monodon, P. orientalis, P. merguiensis, P. penicillatus, P. semisulcatus, P. japonicus, and M. ensis. The more popular species for culture in marine ponds are the sea bass, grouper, red sea bream, yellowtail, rabbitfish, and marine shrimps. RandAqua 8886555529.
Bacterial Imbalance
Imbalance of bacteria in digestive system is linked to overall health and disease. Probiotics promote a healthy balance of gut bacteria and have been linked to a wide range of health benefits. Rand Aqua’s “HULL” is oil based binding agent enriched with gut probiotics. RandAqua 8886555529.
Basics
The steps for starting a aqua farming business includes selecting suitable farm land or area, farm type
cage, tank or pond, cage or pond construction, selecting fish species, feeding, care & management,
harvesting and marketing. RandAqua 8886555529.
White Gut
The White gut is caused by the necrosis of epithelial mucosa and resembles the haemocytic enteritis; the
White fecal matter is caused because of the damage to the hepatopancreas and hepatocytes. The
sloughed cells are released in to the gut and the gut looks white in colour. The fecal matter contains
undigested feed particles but in case of white fecal matter it is from the dead hepatocytes. RandAqua 8886555529.
DO & FCR
Optimizing oxygen levels in rearing systems could significantly improve FCR. Monitoring systems to optimize feeding and reduce FCR is a good step. Mortality and unregistered losses were identified as major factors that impacts FCR and feed use requirements. RandAqua 8886555529.
RMS
Running mortality syndrome RMS symptoms: Antennae are cut and the Uropods turn red colour,
hepatopancreua begins to turn reddish yellow; finally entire body turns dark red in colour, Continuous
internal mortality, The dead shrimp settle at the bottom of the pond and to not come to sides or surface,
White or yellow faecal matter noticed in the gut. RandAqua 8886555529.
Algae
When algae develop quickly in ponds and cause changes in water color and pH fluctuation during a day is larger 0.5, then exchange at least 30% water in pond, Dissolve 2-3 kg sugar/1000 m2 and release evenly
to different locations of pond, keep aeration continuously in a few hours. RandAqua 8886555529.
Fish Meal
Fish meal main protein source for fish and shrimp feed because of the amino acid profile, highly unsaturated fatty acids, palatability and absence of antinutritional factors. Aquafeed rely much on fish meal and fish oil. Plant protein is the future alternative for Fish meal or Fish oil because of the scarcity. RandAqua 8886555529.
Heavy Metals
Heavy metals are toxic to all aquatic biota and cause high mortality of animal larva, fry and fingerling. They accumulate in the gills, heart, liver, kidneys, brain, bones and muscles of animal. The physic chemical forms of heavy metals determine their mobility, availability and toxicity to animal. These metals enter aquaculture systems through various means and constitute a factor detrimental to successful aquaculture. RandAqua 8886555529.
Probiotics
Certain combination of probiotics has ability to increase productivity of Penaeus monodon farming and to improve water quality by decreasing the concentrations of ammonia, nitrite and unwanted bacteria. RandAqua 8886555529.
