Bait goes off faster than your patience in Kuwait heat. A bag of shrimp left on the deck at midday is soft and sour before you finish the first drift, and soft bait flies off the hook on the cast. Most bad bait days are not bad luck; they are a cooler packed the wrong way.
Two things: temperature and meltwater. Warmth starts the breakdown immediately, and sitting in fresh meltwater strips texture and turns shrimp to paste. Sun on the lid hurts more than sun on the bait.
The signs are obvious. The smell turns first, then shrimp go sticky and slide out of the shell, and the colour goes milky. Once that starts, bait will not stay on a hook.
Ice on the bottom, bait in a sealed tub above it, and a light-coloured lid on top. Never leave bait loose in an open bag resting on ice, because meltwater collects around it and ruins the texture.
Set the cooler up the night before: chill the empty box and freeze the water bottles. A box that starts cold lasts several times longer than one that starts warm.
Shrimp is the weakest in heat, so carry small amounts and top up from the cooler in batches instead of leaving the whole bag out. Squid holds better and should travel in its own tub because the smell spreads. Cut bait from a fish you just caught will not last long, so use it within the first couple of hours.
Do not rinse shrimp in fresh water before storing; that speeds spoilage. If you bought a large bag, split it into small tubs and open only one at a time.
For a long trip, salt a spare batch with coarse salt and air-dry it briefly before it goes in the tub. Salted bait holds up in heat, stays on the hook through a hard cast, and works well for bottom fish such as hamour and shaari.
Live bait is a different job. It needs oxygen and clean water, not deep cold. Change a third to half the water every hour or two from the same area, keep the bucket in shade, and never add ice or fresh water directly.
At the end of the trip, do not refreeze bait that has already thawed. Once it has warmed through, refreezing breaks it down and it will not hold on the hook. Keep what is still clean in a sealed tub in the fridge and use it on the next trip.
The Bahr app helps here too: log each trip with the bait you used, the tide, and the sea state, so after a few outings you know which bait works in which conditions. It is free on Google Play.
The short version: sealed ice, separate tubs, shade, and bait topped up in batches. Four habits separate a trip with fresh bait from one where the smell arrives at the dock before you do.
