Catch care

Whether you choose to keep your catch or release it, there are many ways in which you can care for your catch.

When keeping your catch

Recent studies into seafood quality have yielded plenty of information on maintaing the quality of your catch for eating. Many of us are familiar with the technique of Iki Jime, or brain-spiking as it is known. This techinque kills the fish quickl and humanely, and has been found to increase the quality of fish kept for consumption. The website contains all the up to date information you will need.

When releasing your catch

Studies around Australia have shown that about 50% of all fish caught recreationally are released. Deep-hooking and poor handling have been identified as key factors affecting the survival of released fish. Invertebrates are quite hardy and survival after release has been shown to be 100% but handling can cause loss of appendages which can impact on their reproduction, feeding and vulnerability to predation. If you practice catch and release fishing, we have some helpful tips that will allow you the greatest chance of catching that same fish time and time again.

Gear to minimise harm to the fish

  • Using methods and rigs that increase the chance a fish will be hooked in the mouth rather than gut hooked.
  • Lures
  • Barbless or reduced-barb hooks to reduce hook damage and handling time while removing hooks. Alternatively the barbs of hooks can be flattened with pliers.
  • Circle hooks (especially non-offset circle hooks): the point is turned perpendicularly back to the hook shank to form a generally circular, or oval, shape. Circle hooks have the benefit of a >90% rate of mouth hooking and reduced rates of gut hooking, they improve hook-up and landing rates and when using circle hooks strike time is not as important. When using circle hooks here are a few tips to remember: only lightly hook the bait so that the point and barb are exposed or “bridle” the bait, you don’t need to strike, often the fish will hook itself and needle-nosed pliers are a great help when unhooking a fish

Handling the fish

  • Do not use nets with knots which remove protective mucus and scales, instead use a wide mesh and soft-material net to land fish
  • Ideally fish should be left in the water and unhooked there or if taken out of the water, should be returned to the water as soon as possible
  • Use wet hands or a wet cloth to protect the mucus on the fish’s skin. Removal of this mucus decreases the fish’s ability to osmoregulate, decreases physical and chemical protection and decreases its ability to move through the water with ease.
  • Do not place fish on hot or dry surfaces such as metal surfaces that have been exposed to the sun
  • Use long-nosed or needle-nosed pliers to increase the efficiency of hook removal
  • If a fish is deep-hooked or gut-hooked do not remove the hook, instead cut the line as close as possible to the fish’s mouth. Studies have shown this method increases the survival of some species of fish by more than 70% and most fish shed these hooks within a few weeks of being hooked.
  • Ensure invertebrates are untangled before removing them from gear and avoid contact with fragile antennae
  • When weighing fish do not use grips with inbuilt scales as holding fish vertically can break bones in their jaw and cause the separation of spinal vertebrae. Measuring the length of a fish is preferable to weighing, but if you must weigh a fish, try to use a sling to support the fish horizontally
  • When holding fish, hold them horizontally and provide as much support as possible for the entire body

Releasing the fish

  • If fish appear exhausted upon returning to the water (struggling to swim or remain upright), ‘swim’ them before release by pushing the fish backwards and forwards through the water or holding it into the current to increase water flow over its gills. Continue this until the fish starts to show signs of recovery.
  • Fish caught at depths of >20m, such as the popular Dhufish, Breaksea Cod, Baldchin Groper and Pink Snapper, can suffer barotrauma when brought to the surface. This results from the rapid expansion of gases in the swim bladder which puts pressure on internal organs and greatly reduces survival after release. Evidence of barotrauma includes an inflated abdomen, bulging eyes, stomach protruding from the mouth or sometimes there is no evidence where the swim bladder may have burst. The best way to release a fish that has been caught at depths >20m (regardless of whether it shows signs of barotrauma) is to use a release weight, which greatly increases the chance of survival after release. Release weights are available from tackle stores and more information on their use can be found in Recfishwest’s Release Weight publication.
