any tips to make rag and lug last longer

i need to make my bait last longer as i have no car and will be at the mark for a week any tips needed

keep them cool, if you have a cool box use ice packs and change them twice a day depending on how many times you open the box, and don't leave bait directly on the ice packs as this will kill them. if using news paper change daily and take out the dead worms.
If you want to keep them for a long time you are better off keeping them in containers in the fridge with just enough water to cover them and change daily for the first week and take out any dead ones, remember the water must be the same temperature when changing so it must be kept in the fridge. and don't leave them in the sunshine because they will go off in a heartbeat.

if i put them in lrg food containers will i put water and sea weed and how many per 4 litre tub can you do that with lug aswell
