Botanical-based solution for safer transportation and management of fish

Shaldag™ naturally improves fish welfare. This formulation preserves the good condition of fish during the management and transportation. Shaldag™ is a safe formulation that is highly-effective in both sea water and fresh water. Using this botanical-based solution vastly improves post-management acclimation and contributes to the quality of the mucus and fillet.

Field Trials


Field trials were conducted in multiple environments and under all routine management scenarios. These include cold and warm temperatures in both fresh water and seawater. The trials were conducted in hatchery tanks, shipping truck tanks and wellbots.  Results showed that fish welfare was greatly improved in terms of:

  • Plasmatic cortisol
  • Plasmatic lactate
  • Plasmatic glucose
  • CO2 in the tank water
  • Nitrite, nitrate and ammonia
  • Reduction in the loss of fish body scales
  • Lower oxygen consumption
  • Rapid return to feeding (acclimation)
  • Better fish behavior
  • Better flesh quality and final product
