maturity for females. Biery and Daniel Pauly from UBC Fisheries Centre in Canada executed a review on species-specific fin to body-mass ratios in 2012. Their paper concludes that current regulated ratios are not appropriate for all species and that regulations based on a general ratio for all species is inadequate and may be harming fisheries. The ratios used by many fisheries were originally compiled by a politically affiliated group called The Regional Fishery Management Organizations, RFMO. Biery and Pauly collected fin to body-mass ratios for 50 different species and eight different countries and observed that actual fin to body-mass ratios varied by species and location. Species specific mean ratios ranged from 1.1% to 10.9% and estimated mean ratios by country ranged from 1.5% to 6.1% indicating that current regulations will crash fisheries and not promote population growth. Away from the commercial side of conservation, there are tagging efforts to monitor gulper populations. Tagging is a common ecological tool to study the species characteristics. A large problem with monitoring the populations of Australian and Indonesian dogfish is that discriminating between the seven local species by morphological attributesalone is unreliable. In 2012 a study conducted by Ross Daley, Sharon Appleyard, and Matthew Koopman from the CSIRO Marine and Atmospheric Research Center in Hobart, Australia aims to help monitored recovery plans by implementing a new catch data verification plan. Their study focuses on using the 16s mitochondrial gene region to differentiate these species and when sequenced, all but C. harrissoni and C. isodon were distinguishable. They concluded that 16s gene is a strong marker suitable for fishery catch verification and that using this technique is a reliable and efficient system for routine testing. However, specialized primers needed for trials are sensitive to decay. Therefore, preservation problems need to be researched to further the prospective use of a 16s mitochondrial classification. This system for routine testing is only available to scientists and would require substantial training for fishermen to be able to use this technique. Uncertainties and inconsistency in data While information concerning gulper sharks exists, there is no place to centrally compile the information so that other researchers may easily obtain it. This leads to repetition in basic data and less depth into the subject matter. Information presented may also be inaccurate as many genus of Centrophorus are morphologically similar. While attempts are being made to make it easier to identify different genus,
