To: Ref. Dot buying fish to replace a significant number of fish that die in home aquaria. Stores suffer fish losses before the fish are sold, but the profits made from customers buying replacement fish are high enough that stores do not have incentive to purchase healthy fish to avoid fishes dying in stores. One option for a simple, top down legislative solution to reform the marine aquarium trade would be to implement a mandatory warranty for all vendors in the United States. A warranty would address two problems: 1. A warranty would provide consumer protection against buying (and then paying again to replace) an inferior product. 2. A warranty would provide a simple, top down solution to motivate stores to only purchase from suppliers that do not use harmful collection or handling practices throughout the supply chain. A warranty would only be an effective tool if stores lost money with a warranty in place. When facing an expected loss in profits, stores would have an incentive to look for alternative ways to make money. Stores could regain some of their losses if they reduced the number of fish dying in customers' homes by purchasing sustainably sourced fish. If a mandatory warranty provided a financial incentive for stores to reform their supply chain, a warranty could be a simple, effective tool to promote change. Methods for warranty analysis To run a warranty analysis, we first had to consider the current state of the market and how the revenue and costs would change if a mandatory warranty were implemented. For this analysis, we only included costs and revenues directly related to fish sales. We did not include fixed costs of maintaining and running a store, which we assumed were constant and not directly related to fish sales. After analyzing how a store's costs and revenues would change with the implementation of a mandatory warranty under current practices, the final step was to calculate how the costs and revenues would change under a mandatory warranty if all fish supplied to stores were sustainably sourced. In order to run this analysis, we used the following equation to represent the revenues and costs of fish -related sales for U.S. stores: Total Profits Related to Fish Sales = Customer purchase price — Store's initial investment In fish + Expected future replacement sales — Costs of in-store mortality With a warranty, we could use the same equation except stores could charge a price premium for a warranty, and stores would have to pay the costs of replacing fish NRI Appendix G Species used in supply chain analysis Species Common name(s) Abude du 'vai iensis Common ser giant 1 Ser xeant ma'or damselfish Acanthurus leucosternon Powderblue sur eonfish / Powder blue tan Acanthurus lineatus Lined sur eonfish / Clown tan Acanthurus maculice )s Sot -face surgeon f Maculice s tang Acanthurus nigricans Whitecheek surgeonfish / velvet surgeon / Powder brown tang Acanthurus olivaceus Orauge®blotch surcon / Oran eband surgeon / Orange shoulder tan Acanthurus pyroferus Mimic sur eonfish 'Chocolate tang Am hi rion clarkii Yellow -tail clownfish / Clarks clown Am hi rion eph!ppium Red saddleback anemonefish ./ Saddle anemone Am hi prion ocellaris Clown anenomefrsb / Oeellaris clown Am hi rion ercula Orange. clownfish / Percula clownfish Am hiprion po4,mnus Saddleback clownfish / Black saddle clown Am hiprion sandaracinos Orange anemonefish / Orange skunk clown A olemichth s trimaculatus Threes of an elfish 1 Fla fin angel Bodianus diana Diana's bo fish Bodianus mesothorax M_e_sotho_rax hogfish 1 Black belt ho fish ?
