การเลี้ยงกุ้งก้ามแดงที่อัตราความหนาแน่นที่แตกต่างกันโดยใช้วัสดุหลบซ่อน

Abstract

Red lobster cultivation experiment at different density rates using 3 levels of hiding material including, 10, 20, and 30 characters per square meter. To study the optimal density rate growth rate, survival rate and productivity were planned randomized controlled trials over a 2-month period.The results showed that red lobster culture in a cage at a density rate of 10, 20, 30 per square meter.The average final weight was 10.80, 8.17 and 8.52 grams. The average final weight was 6.49, 6.33 and 6.19 cm. Daily weight gain of 10.76, 9.15 and 8.49 grams, survival rates of 83.33, 75, and 82.23 percent. And the exchange rate of meat was 0.29, 0.25 and 0.31. Statistical analysis showed no statistical differences. Economical cost and return analyzes showed that the experimental set at density rates of 10, 20 and 30 samples per square meter were found. The yield was 0.098, 0.258 and 0.358 kg. Revenue from the sale of red lobster was 78.40, 206.40 and 286.40 baht, with yield cost of 29.98, -3.09 and -0.21 per kg. Has the lowest production cost -3.09 kg. For investment, it was found that growing red lobster in cages at density of 10, 20 and 30 per meter rails. Yields were -72.57, -73.26 and -76.02 percent, respectively. Red lobster was fed in cages at a density of 10 per meter. It is appropriate as it provides high net profit and income.
