Bansod had expected to speak with a few artisans and learn about their craft but was flabbergasted by what he saw. Amey Bansod says shell fishermen in India often use a fishing technique similar to bottom trawling, which involves dragging a large net along the seafloor. In addition, CITES requires that source countries set fishing quotas to ensure that trade in these species is sustainable. For example, weight-bearing exercises like squats, bench presses, and leg presses more effectively improve bone mineral density (BMD) than stationary cycling (9). 2005-2023 Healthline Media a Red Ventures Company.
