印度对虾养殖场的平均产量(池面基础)：凡纳滨对虾(n=89)的平均产量为7.86+/-1.04(东南)m.t./ha/yr；斑节对虾(n=11)的平均产量为3.88 m.t./ha/yr。凡纳滨对虾的平均饲料转化率为1.48+/-0.04，斑节对虾为1.24+/-0.12。生产池塘、配套面积和饲料原料的用地平均为0.634+/-0.053公顷/m.t。凡纳梅和0.716+/-0.087 ha/m.t.对斑节对虾来说。在没有水交换的农场使用的咸水量为18522+/-4065m(3)/m.t。凡纳滨对虾和9528m(3)/m.t.对斑节对虾来说。农场交换用水149,188 m(3)/m.t。凡纳梅和191,500 m(3)/m.t.对斑节对虾来说。饲料中的淡水含量为1678+/-508m(3)/m.t。凡纳滨对虾和1401+/-137m(3)/m.t.对斑节对虾来说。农场建设和维修、农场经营以及饲料和石灰原料的平均能耗为82.14+/-9.08GJ/m.t。Vannamei和59.03+/-24.92GJ/m.t.对斑节对虾来说。饲料中用于制作鱼粉的野生鱼为1209公斤/公吨。凡纳滨对虾和1611 kg/m.t.对斑节对虾来说。印度的农场基础设施、池塘管理方法、产量和资源使用与泰国和越南以前报告的对虾养殖场相似。
Shrimp farms in India had average yields (pond surface basis) of 7.86 +/- 1.04 (SE) m.t./ha/yr for Litopenaeus vannamei (n = 89) and 3.88 m.t./ha/yr for Penaeus monodon (n = 11). Average feed conversion ratio was 1.48 +/- 0.04 for L. vannamei and 1.24 +/- 0.12 for P. monodon. Land use for production ponds, supporting area, and feed ingredients averaged 0.634 +/- 0.053 ha/m.t. for L. vannamei and 0.716 +/- 0.087 ha/m.t. for P. monodon. Saline water volume used at farms without water exchange was 18,522 +/- 4065 m(3)/m.t. for L. vannamei and 9528 m(3)/m.t. for P. monodon. Farms exchanging water used 149,188 m(3)/m.t. for L. vannamei and 191,500 m(3)/m.t. for P. monodon. Freshwater embodied in feed was 1678 +/- 508 m(3)/m.t. for L. vannamei and 1401 +/- 137 m(3)/m.t. for P. monodon. Average energy use for farm construction and repair, farm operations, and embodied in feed and liming materials was 82.14 +/- 9.08 GJ/m.t. for L. vannamei and 59.03 +/- 24.92 GJ/m.t. for P. monodon. Wildfish used to make fishmeal included in feed was 1209 kg/m.t. for L. vannamei and 1611 kg/m.t. for P. monodon. Farm infrastructure, pond management methods, yields, and resource use in India were similar to those previously reported for shrimp farms in Thailand and Vietnam.
