In order to potentially evaluate tradeoffs in fisheries management, we will construct a value chain to describe how the different parts of the fishing industry contribute to the overall economy and social system.<\/p>\r\n\r\n<div class=\"textbox textbox--sidebar shaded\">We need to define the size of the ecosystem (in km<sup>2<\/sup>) as value chain analyses operate with amounts, not densities. Hence, landings per unit area (t km<sup>-2<\/sup> year<sup>-1<\/sup>) should be multiplied with the area (km<sup>2<\/sup>) to obtain total landings (t year<sup>-1<\/sup>)<\/div>\r\n<p style=\"font-weight: 400\">We will use the Anchovy Bay ecosystem model that we constructed in a previous tutorial (<a href=\"https:\/\/ln5.sync.com\/dl\/7e8920510\/cpr3mexp-nhn9ab3i-7cg883k8-rdav86dn\">download<\/a>). First open the model and check that it is mass balanced (<em>Ecopath &gt; Output &gt; Basic parameters<\/em>). Then go to <em>Ecopath &gt; Input &gt; Model parameters<\/em> and set the model area to 10000 km<sup>2<\/sup> (if not already entered). Also make sure that you have selected the appropriate monetary units. As Anchovy Bay is located somewhere in Europe, lets choose Euros for now.<\/p>\r\n<p style=\"font-weight: 400\">Then let\u2019s go to <em>Ecopath &gt; Input &gt; Fishery &gt; Off-vessel price<\/em>. Currently we have five fleets. Each functional group-fleet combination requires an off-vessel price (change the default values). A ton of seals should be worth \u20ac 600, a ton of cod should be worth \u20ac 1,400, a ton of whiting should be \u20ac 200, a ton of mackerel should be worth \u20ac 350, a ton of anchovy should be \u20ac 160 and a ton of shrimp \u20ac 17,000. However, we know that anchovies when caught by bait boats are landed in better condition and hence are worth more. Please include a price for them of \u20ac 160 per ton when caught by bait boats.<\/p>\r\n<p style=\"font-weight: 400\">Next go to <em>Ecopath &gt; Output &gt; Tools &gt; Value chain<\/em>. This will load the value chain plug-in of EwE. On the parameters form, check \u201c<em>Run with Ecopath<\/em>\u201d. Then go to the flow form. Select <em>Add &gt; Create producers for fleets<\/em>, then click <em>Arrange<\/em>, and say <em>Yes<\/em>, if it asks if you want to save. You should now have five fleets as boxes on your flow chart form. The five producers will be linked to the EwE model and pick up baseline landings (and off-vessel prices) by fleets from the base model.<\/p>\r\n<p style=\"font-weight: 400\">Next, we need to add processors, distributors, wholesalers, retail sellers and consumers to the value chain (and link them together). You can rename the enterprises in the properties table (click on a box and look at the right section of the screen).<\/p>\r\n\r\n<ol>\r\n \t<li><em>Shrimpers<\/em>, <em>Trawlers<\/em> and <em>Seiners<\/em> sell their catch to <em>Primary processors<\/em> who fillet the fish and cut it into portions. Fresh seafood products are then sold to <em>Coolers<\/em>, distributors that transport them in refrigerated containers to <em>Fresh seafood wholesalers<\/em>. Retailers like <em>Restaurants<\/em> that cater <em>Tourists<\/em> and <em>Fish mongers<\/em> that sell fish to <em>Local consumers<\/em> purchase their seafood from the <em>Fresh seafood wholesalers<\/em>.<\/li>\r\n \t<li><em>Seiners<\/em> and <em>Bait boats<\/em> sell their catch to the <em>Canneries<\/em>. <em>Canneries<\/em> place their production in <em>Warehouses<\/em> using <em>Trucks<\/em>. <em>Trucks <\/em>are a distributing company that does not purchase the cannery\u2019s production. They charge a fee for the service of delivering the product to a warehouse that needs it (<em>i.e.<\/em>, acts like a broker). <em>Warehouses<\/em> sell products to <em>Supermarkets<\/em> where <em>Local<\/em> and <em>Regional consumers<\/em> can place their orders.<\/li>\r\n \t<li><em>Trawlers<\/em> also sell part of their catch to <em>Freezing plants<\/em>. These sell their production to a distributing company, <em>Frost Trucks<\/em>, that sell this production to the same <em>Warehouses<\/em> that purchase canned seafood.<\/li>\r\n \t<li><em>Sealers<\/em> sell their catch to the <em>Anchovy Bay Company (ABC<\/em>), which processes seals into fancy pelts. These are directly sold to <em>Regional consumers<\/em>.<\/li>\r\n<\/ol>\r\n<p style=\"font-weight: 400\">Your value chain should look something like in Figure 1.<\/p>\r\n\r\n<div class=\"textbox shaded\"><strong><img class=\"size-full wp-image-3806 aligncenter\" src=\"https:\/\/pressbooks.bccampus.ca\/ewemodel\/wp-content\/uploads\/sites\/1902\/2023\/10\/value-chain.png\" alt=\"\" width=\"864\" height=\"392\" \/>\r\nFigure 1<\/strong>. Screenshot of value chain implementation for Anchovy Bay. The enterprises are arranged with producers (= fleets in EwE model) in the first column (with a hook icon). Processors are in the second column (with building icon), distributors in the third column (with semi truck icon), whole sellers in the fourth column (with shop icon), retailers including restaurants are in the fifth column (with shopping cart icon), and consumers are in the last column. The boxes in the value chain are connected with arrows, the width of which indicate what proportion of the flow leaving a given box is passed on to the connected box. The producers receives catches from the EwE model (all modules) and passes these on through the value chain.<\/div>\r\n<p style=\"font-weight: 400\">However, you may notice that the <em>Trawlers<\/em> and <em>Seiners<\/em> are color marked in your flowchart. This lets us know that we need to specify how the landings are distributed between the processors they supply. You do this by clicking <em>Move<\/em>, then click the link between (e.g<em>.<\/em>, <em>Trawlers<\/em>and <em>Primary Processors<\/em>). In the properties table to the right, select a functional group (e.g.<em>,<\/em> cod), and add a biomass ratio (e.g<em>.,<\/em> 0.5). However, it is much easier to add all of this in <em>Value chain &gt; Components &gt; Landings<\/em>.<\/p>\r\nWe can for this tutorial populate the Anchovy Bay value chain by downloading a spreadsheet with input tables from <a href=\"https:\/\/ln5.sync.com\/dl\/b5142abd0\/shf4aksj-2bzu84fa-gvmqjau3-ym7z2fqd\">this link<\/a>. For convenience, we have included a table with the landing distributions in Tabel 1.

Here's a <a href=\"https:\/\/ln5.sync.com\/dl\/017360cf0\/7etk8cra-mxszd9hh-hkudiq6d-59xt5ntq\">link<\/a> to an Anchovy Bay model with the value chain database.","rendered":"<div class=\"textbox textbox--learning-objectives\">\n<header class=\"textbox__header\">\n<p class=\"textbox__title\">Learning Objectives<\/p>\n<\/header>\n<div class=\"textbox__content\">\n<ul>\n<li>\n<div><span lang=\"EN-US\">Obtain experience building value chains in EwE<\/span><\/div>\n<\/li>\n<\/ul>\n<\/div>\n<\/div>\n<p style=\"font-weight: 400\">The fishing industry around Anchovy Bay is important for peoples\u2019 livelihoods and health, providing both jobs and food. In order to potentially evaluate tradeoffs in fisheries management, we will construct a value chain to describe how the different parts of the fishing industry contribute to the overall economy and social system.<\/p>\n<div class=\"textbox textbox--sidebar shaded\">We need to define the size of the ecosystem (in km<sup>2<\/sup>) as value chain analyses operate with amounts, not densities. Hence, landings per unit area (t km<sup>-2<\/sup> year<sup>-1<\/sup>) should be multiplied with the area (km<sup>2<\/sup>) to obtain total landings (t year<sup>-1<\/sup>)<\/div>\n<p style=\"font-weight: 400\">We will use the Anchovy Bay ecosystem model that we constructed in a previous tutorial (<a href=\"https:\/\/ln5.sync.com\/dl\/7e8920510\/cpr3mexp-nhn9ab3i-7cg883k8-rdav86dn\">download<\/a>). First open the model and check that it is mass balanced (<em>Ecopath &gt; Output &gt; Basic parameters<\/em>). Then go to <em>Ecopath &gt; Input &gt; Model parameters<\/em> and set the model area to 10000 km<sup>2<\/sup> (if not already entered). Also make sure that you have selected the appropriate monetary units. As Anchovy Bay is located somewhere in Europe, lets choose Euros for now.<\/p>\n<p style=\"font-weight: 400\">Then let\u2019s go to <em>Ecopath &gt; Input &gt; Fishery &gt; Off-vessel price<\/em>. Currently we have five fleets. Each functional group-fleet combination requires an off-vessel price (change the default values). A ton of seals should be worth \u20ac 600, a ton of cod should be worth \u20ac 1,400, a ton of whiting should be \u20ac 200, a ton of mackerel should be worth \u20ac 350, a ton of anchovy should be \u20ac 160 and a ton of shrimp \u20ac 17,000. However, we know that anchovies when caught by bait boats are landed in better condition and hence are worth more. Please include a price for them of \u20ac 160 per ton when caught by bait boats.<\/p>\n<p style=\"font-weight: 400\">Next go to <em>Ecopath &gt; Output &gt; Tools &gt; Value chain<\/em>. This will load the value chain plug-in of EwE. On the parameters form, check \u201c<em>Run with Ecopath<\/em>\u201d. Then go to the flow form. Select <em>Add &gt; Create producers for fleets<\/em>, then click <em>Arrange<\/em>, and say <em>Yes<\/em>, if it asks if you want to save. You should now have five fleets as boxes on your flow chart form. The five producers will be linked to the EwE model and pick up baseline landings (and off-vessel prices) by fleets from the base model.<\/p>\n<p style=\"font-weight: 400\">Next, we need to add processors, distributors, wholesalers, retail sellers and consumers to the value chain (and link them together). You can rename the enterprises in the properties table (click on a box and look at the right section of the screen).<\/p>\n<ol>\n<li><em>Shrimpers<\/em>, <em>Trawlers<\/em> and <em>Seiners<\/em> sell their catch to <em>Primary processors<\/em> who fillet the fish and cut it into portions. Fresh seafood products are then sold to <em>Coolers<\/em>, distributors that transport them in refrigerated containers to <em>Fresh seafood wholesalers<\/em>. Retailers like <em>Restaurants<\/em> that cater <em>Tourists<\/em> and <em>Fish mongers<\/em> that sell fish to <em>Local consumers<\/em> purchase their seafood from the <em>Fresh seafood wholesalers<\/em>.<\/li>\n<li><em>Seiners<\/em> and <em>Bait boats<\/em> sell their catch to the <em>Canneries<\/em>. <em>Canneries<\/em> place their production in <em>Warehouses<\/em> using <em>Trucks<\/em>. <em>Trucks <\/em>are a distributing company that does not purchase the cannery\u2019s production. They charge a fee for the service of delivering the product to a warehouse that needs it (<em>i.e.<\/em>, acts like a broker). <em>Warehouses<\/em> sell products to <em>Supermarkets<\/em> where <em>Local<\/em> and <em>Regional consumers<\/em> can place their orders.<\/li>\n<li><em>Trawlers<\/em> also sell part of their catch to <em>Freezing plants<\/em>. These sell their production to a distributing company, <em>Frost Trucks<\/em>, that sell this production to the same <em>Warehouses<\/em> that purchase canned seafood.<\/li>\n<li><em>Sealers<\/em> sell their catch to the <em>Anchovy Bay Company (ABC<\/em>), which processes seals into fancy pelts. These are directly sold to <em>Regional consumers<\/em>.<\/li>\n<\/ol>\n<p style=\"font-weight: 400\">Your value chain should look something like in Figure 1.<\/p>\n<div class=\"textbox shaded\"><strong><img loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-3806 aligncenter\" src=\"https:\/\/pressbooks.bccampus.ca\/ewemodel\/wp-content\/uploads\/sites\/1902\/2023\/10\/value-chain.png\" alt=\"\" width=\"864\" height=\"392\" srcset=\"https:\/\/pressbooks.bccampus.ca\/ewemodel\/wp-content\/uploads\/sites\/1902\/2023\/10\/value-chain.png 864w, https:\/\/pressbooks.bccampus.ca\/ewemodel\/wp-content\/uploads\/sites\/1902\/2023\/10\/value-chain-300x136.png 300w, https:\/\/pressbooks.bccampus.ca\/ewemodel\/wp-content\/uploads\/sites\/1902\/2023\/10\/value-chain-768x348.png 768w, https:\/\/pressbooks.bccampus.ca\/ewemodel\/wp-content\/uploads\/sites\/1902\/2023\/10\/value-chain-65x29.png 65w, https:\/\/pressbooks.bccampus.ca\/ewemodel\/wp-content\/uploads\/sites\/1902\/2023\/10\/value-chain-225x102.png 225w, https:\/\/pressbooks.bccampus.ca\/ewemodel\/wp-content\/uploads\/sites\/1902\/2023\/10\/value-chain-350x159.png 350w\" sizes=\"auto, (max-width: 864px) 100vw, 864px\" \/><br \/>\nFigure 1<\/strong>. Screenshot of value chain implementation for Anchovy Bay. The enterprises are arranged with producers (= fleets in EwE model) in the first column (with a hook icon). Processors are in the second column (with building icon), distributors in the third column (with semi truck icon), whole sellers in the fourth column (with shop icon), retailers including restaurants are in the fifth column (with shopping cart icon), and consumers are in the last column. The boxes in the value chain are connected with arrows, the width of which indicate what proportion of the flow leaving a given box is passed on to the connected box. The producers receives catches from the EwE model (all modules) and passes these on through the value chain.<\/div>\n<p style=\"font-weight: 400\">However, you may notice that the <em>Trawlers<\/em> and <em>Seiners<\/em> are color marked in your flowchart. This lets us know that we need to specify how the landings are distributed between the processors they supply. You do this by clicking <em>Move<\/em>, then click the link between (e.g<em>.<\/em>, <em>Trawlers<\/em>and <em>Primary Processors<\/em>). In the properties table to the right, select a functional group (e.g.<em>,<\/em> cod), and add a biomass ratio (e.g<em>.,<\/em> 0.5). However, it is much easier to add all of this in <em>Value chain &gt; Components &gt; Landings<\/em>.<\/p>\n<p>We can for this tutorial populate the Anchovy Bay value chain by downloading a spreadsheet with input tables from <a href=\"https:\/\/ln5.sync.com\/dl\/b5142abd0\/shf4aksj-2bzu84fa-gvmqjau3-ym7z2fqd\">this link<\/a>.
