Intensification is part of modern shrimp farming technology, feed, and high stocking density. High density could save time and production costs. This research aimed to determine the optimal tolerance of shrimp larvae with high stocking density per bag unit without oxygen liquid in terms of environmental physiology (ecophysiology) and economic feasibility aspects (bioeconomics). The shrimp larvae used were post-larvae 10 with a weight of 0.0026 ± 0.0021 g, which were previously fasted. The method used was a simulation of a three-hour trip with treatments: 200 larvae/packing (control), 400 larvae/packing, and 600 larvae/packing. The treatment for each packing was 450 ml of water and oxygen gas and added ice cubes in each styrofoam during delivery at night. The results showed that the stocking density of 600 larvae/packing had the best value. In terms of ecophysiology, the survival rate was highest when arriving at the location, with 98.20% of total larvae. The lowest oxygen consumption in the metabolic process was 0.76 ± 0.10 mg/L. Reviewing a bioeconomic, the potential profit per packing reaches IDR 995,528. It can be concluded that the use of oxygen gas and the addition of ice cubes in transportation increased the survival of shrimp larvae.
