We are happy to report more great news to our shark ohana! Our bill SB 2079 for banning the purposeful killing of sharks and rays PASSED THE SENATE and is now going to the house for a vote! The time to use your voice has come again. Help protect Hawaii’s sharks and rays by submitting your support for SB 2079! Please help by emailing “” with the subject line "Attn: Chair Ing In Support of SB 2079" and tell them why you believe Hawaii should further protect sharks and rays! DEADLINE: Monday March 12th at 9:45am.  It can be a few words or a few pages, whatever you'd like! Even if you’ve submitted one before, please submit again so the bill can pass this next step! Any submitted testimonies from you will help! We need to get as many written testimonies sent in soon before the hearing on Tuesday! After submitting your testimony, please encourage your friends and family to do the same. Thank you to anyone who decides to help sharks and rays in Hawaii.

Example Testimony for SB 2079 for Reference

Check out this example testimony for reference and feel free use bits and pieces of it as a resource to write in your own words why sharks are important. 

I strongly support SB 2079. Sharks are rays are a vital component of healthy marine ecosystems that have experienced rapid declines throughout the last decades. As apex predators sharks are at the top of the food chain, therefore maintaining balance of the  the ecosystem by regulating abundance of marine life in lower trophic levels and acting as the immune system of our oceans by picking off the weak, sick and overpopulated keeping fish stocks healthy. 
Support for Ecological Importance
Ecosystem models predict that the removal of sharks can result in complex community changes, including trophic cascades, mesopredator release, and consequent declines in some commercial fish and cascading changes in some coastal ecosystems (Ferretti et al. 2010). Additional research indicates that the removal of shark and rays may alter size, structure and population parameters in response to changes in species abundance (Stevens et al. 2000). 
In the context of ecosystem level changes specific to Hawaii, a study published in 2000 examined the potential long term impacts of the removal of sharks with the use of a dynamic model ECOSIM that predicts changes in biomasses, yields, and consumption for each group through time. They found that when tiger sharks were removed from the model a total and rapid crash in the abundance of tuna and jacks, and an increase in bottom fishes occurred due to increases in seabird populations which compete with tunas and jacks for food and where no longer subject to top down control by tiger sharks (Stevens et al. 2000). While ecological relationships are very complex and difficult to simulate this study highlights the potential for unforeseen and unintended consequences when sharks are removed.
Further evidence for the ecological importance of sharks can be found when comparing the density, size, and biomass of reef fishes in northwestern Hawaiian islands, a large, remote, and lightly fished area, and the main Hawaiian islands (MHI), an urbanized, heavily fished area. The study by Friedlander & DeMartini in 2002 revealed dramatic differences between the two ecosystems, as grand mean fish standing stock in the NWHI was more than 260% greater than in the MHI, more than 54% of the total fish biomass in the NWHI consisted of apex predators, (primarily sharks and jacks) whereas this trophic level accounted for less than 3% of the fish biomass in the MHI. The study concluded these differences represent both near-extirpation of apex predators and heavy exploitation of lower trophic levels in the MHI compared to the largely unfished NWHI (Friedlander & DeMartini 2002).
A 2008 report by the DLNR-DAR of Hawaii found that Oahu’s reefs have around 1/10th the biomass of apex predators (Willaims et al. 2008) when compared to remote inaccessible reefs, indicating that anthropogenic pressures through the main Hawaiian islands has dramatically reduced populations of sharks and rays that are particularly susceptible to over-exploitation due to life history characteristics including slow growth, late attainment of sexual maturity, long life spans, low fecundity (Stevens et al. 2000). 
Support for economic value of sharks
Sharks are also not only ecologically important, but also economically important. Sharks are more alive according to a 2013 study by Cisneros-Montemayor  et. al which estimates participants in the shark ecotourism industry expend > USD 314 million per year and is projected to grow based on current trends to an estimated > USD 780 million in tourist expenditures in the next 20 years (Cisneros-Montemayor  et al. 2013). Similarly, a 2012 study by Vianna et. al provides support for the argument of non-extractive resource use based on data from shark ecotourism operations in Palau which generates USD$18 million per year, and states that the estimates value of the population of approximately 100 sharks used in the operation to be at most USD$10,800 if they were harvested which is a fraction of worth of these animals as a non-consumptive resource (Vianna et al. 2012). 
Based on the scientific studies cited above there is a very clear argument for protecting sharks and rays in Hawaiian waters for their ecological, economic, and intrinsic value. The long term ecological implications of removal of apex predators are difficult to document, but when it comes to conserving such a vital component of our marine ecosystems the precautionary approach should be taken to ensure healthy populations of these animals persist for future generations. Some may oppose this bill because they believe it will be difficult to fund enforcement, but some of the business that stand to gain (shark ecotourism businesses) from this bill could participate in a voluntary “shark watching tax” of $5 for every person who wants to commercially see a shark alive to help with any costs of enforcing this law.  We as a community could help to provide the evidence to DLNR to enforce this law leaving no logical reason not to support this bill.
