Although it is not physically possible to trawl on reef structures, significant long-term damage can occur if sensitive habitat areas like corals, sponges and seagrass beds are trawled. To ensure these sensitive habitat areas are protected from trawling, management arrangements such as area closures are extensively used.There is no reason why any animal that has had a 90% decline in modern times should still continue to be harvested.” Walker, Terence I.

Giri, K and Hall, K 2015, South Australian Recreational Fishing Survey. Fisheries Victoria Internal Report Series No. 62. Like gummy sharks, school sharks are very important to the southern Australian commercial fishing industry, and are commonly sold to be eaten both locally and overseas.

Retrieved 2020-04-17.There are limited recorded fossils for the genus Mustelus and, therefore, insufficient fossil findings on the species Mustelus ravidus. [2] Ultimately, the genus Mustelus evolved into species presenting either placental viviparity or aplacental viviparity. Thus, all Mustelus produce live young; however, only some possess a placental attachment during gestation (placental viviparity). Conversely, aplacental viviparity indicates the absence of a placental attachment throughout the pregnancy. The grey gummy shark is identified as a placental and viviparous species. Accordingly, Boomer et al. (2012) found that the most recent common ancestor of the placental clade existed earlier prior to those without it (aplacental clade), which suggests that the placental species had undergone a recent divergence. Moreover, the molecular dating conducted by Boomer et al. strongly supports the theory that divergence was an integral factor in speciation in Mustelus. (2012) It is also believed that the recent and rapid speciation in the genus is a factor for its complex taxonomy. [2] Distribution and habitat [ edit ] Gillnets have a minimal impact on the seafloor as they are stationary when set. Gillnets have the potential to interact with marine mammals, although when set properly, larger predatory sharks and marine mammals will bounce off the firm netting.

Most of the larger gummy sharks arecaught in the southern end of PortPhillip Bay around areas such as theColes Channel near St Leonards, MudIsland, the Simmons Channels outfrom Queenscliff, and the SorrentoChannel. In the middle and northernend of Port Philip Bay gummy sharksare often caught in most of the areaswhere snapper can be expected. InWestern Port they can be caught ina wide variety of shallow and deepwater locations. In general, the population distribution of the genus Mustelus, which the grey gummy shark is a part of, requires active swimming and is heavily associated with coastal-benthic (or ground-dwelling) areas. [2] Specifically, the grey gummy shark is endemic to Australia. It is commonly found in continental shelves, particularly the north-west shelf off Western Australia, and usually at the depth range 106–300 metres. [3] [6] This oceanic range is usually referred to as the twilight zone which spans from 200 metres to 1000 metres and is partly or wholly impenetrable by sunlight. Notably, the grey gummy shark is often found in the upper range of the twilight zone.Another important consideration is the price. You’ll want to make sure that you’re getting a good deal on your gummy sharks.
