An economic biodiversity index and an environmental  quality variable have been included and the  parameters are estimated using Schnute method. This  exercise focuses on the dynamics of the profit- maximising regime and explores the dynamic maximum  economic yield and maximized net present-value of  fishery profit. Small perturbations in discount rate  and intrinsic growth rate have been done as part of  sensitivity analysis and their impact on optimal  profit has been examined under different economic  biodiversity scenarios. Results show that  policymakers have to be careful while framing  policies involving trade-offs between the  development of fishing activities and the thriving  tourism in Digha. Our analysis finds that in the  Digha fishery there exists a trade-off between  economic biodiversity conservation and profit  maximization.\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9783838353005\"\u003e\u003ch3\u003eAN ECOLOGICAL ECONOMIC ANALYSIS IN SEARCH OF A TRADE OFF\u003c\/h3\u003e\u003c\/div\u003e","brand":"Autorenwelt Shop","offers":[{"title":"Softcover - 9783838353005","offer_id":39499068702813,"sku":"9783838353005","price":79.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/69da156a-2d89-464f-84e6-63ab6ba35081.jpg?v=1775888339","url":"https:\/\/shop.autorenwelt.de\/products\/bioeconomic-modelling-for-fish-biodiversity-and-profitability-von-anita-chattopadhyay-gupta","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
