With the scallop season opening on Saturday 15th of July in Wellington (Central Region) it is important that we understand the regulations and the safety issues involved for divers in gathering scallops. These regulations do vary around the country so please check before you go diving and note that the Malbourough Sounds (Challenger Region) is closed until further notice. Having the NZ Fishing Rules App enables you to check the current rules as you travel the country.
It has always been said that scallops are amongst the biggest ‘killers’ of divers as we focus on collecting our quota and forget to monitor our depth, time and air supply. Divers are often diving in areas with boats who may be dredging for scallops so using a dive flag is important for diver safety.
Scallops live on the sea floor of sheltered coastal waters ranging from sand, silt and mud. These areas are generally associated with low visibility and it is important that divers maintain contact and follow lost buddy procedures when separated, search for 1min before ascending and regrouping on the surface. If your buddy hasn’t surfaced within a nominated time frame (3-5mins) call for help.
Scallops can be found from low tide level to depths of 50 metres or more. Large populations are often found at depths of 10-25 metres. Divers usually perform square dive profiles with direct ascents to the surface. With a heavy catch bag and limited visibility it can be difficult to maintain safe ascent rates and perform safety stops increasing the risk of Decompression Sickness (DCS). Using a liftbag (correctly) or sending up a float and then bringing the catch bag up from the surface can help reduce these risks.
If you haven’t dived since last season please check your gear is in good working order, that you have fresh air in your tank and that you are mentally and physically prepared for your dive.
Scallops are my favourite seafood and I hate to think that anyone will get themselves into trouble collecting dinner or in my case an entree.
Have fun out there and stay safe
