Question
1. What is Canada's current goal for % ocean area protected by 2020?
2. Find a current Marine Protected Area and find out what it's protecting and what activities are allowed and excluded
3. Find a sustainable fisheries from anywhere in the world and find out what makes it sustainable.
Before we begin this week's lab, let's consider how students are ofen tught about how n students are often taught about how new species evolve from existing species (the common ancestor) and how this is depicted. You instructor state that "species A gives rise to species B and C" or "species A" (refer to the slide provided in the lab: this is usually depicted in the simple fo part of the figure). But what does this really mean? Often, students are left with the misconce at might often hear an B and C evolved from species due to som e chance event, two new species suddenly originate from species A, when in actual fact. the process of speciation can last over hundreds of generations. With that in mind, have a look at t provided in the lab and discuss with your group members what the diagram is trying to depict and answer the following questions in the space provided on the next page: I) What do the different coloured circles represent? 2) How many arrows are pointing at each circle? 3) pointing to? 4) What does each horizontal row of circles represent? 5) What does the triangle represent? 6) At the 7th horizontal row of circles, are B & C separate populations of species they now separate species B & C? Briefly explain why- What are the arrows A r are I. Provide the answers to the previous question in the space below. 2) 3) 4) 5)Explanation / Answer
1. CPAWS National Oceans Program Director Sabine Jessen, says that Canada has made international commitments to protect 10% of our ocean by 2020, we have a great deal of work to do in a short amount of time. The 10% target is a step on the way to a longer-term goal of protecting 50% of our ocean estate – to give the full diversity of marine life the best possible chance of recovery and survival.
2. The Canadian Parks and Wilderness Society reveals that out of the 10 countries with the largest ocean estates, Canada ranks the lowest in terms of marine protected areas. At just over 1% of its ocean territory protected, Canada ranks lower than China at 2%, and much lower than Australia, the United States and the United Kingdom, which have protected 36%, 30%, and 17% of their ocean respectively.
Jessen and her colleagues examined three other jurisdictions, which have taken a network approach to MPA establishment – Scotland, Australia and California, and identified eight factors we need to address if we are going to catch up with faster jurisdictions in the ocean protection fleet.
Jessen also notes that successful marine protection efforts included:
3. sustainable fisheries guarantees there will be populations of ocean and freshwater wildlife for the future. Aquatic environments are home to countless species of fish and invertebrates, most of which are consumed as food. Seafood is respected all over the world, in many diverse cultures, as an important source of protein and healthy fats.
In the Philippines, the Tagbanua people have traditionally employed fishing practices that simultaneously harvest and maintain fish populations. They continue to follow these practices today.
Tagbanuas fish for specific species only during certain times of the year, determined by tides and the moon, allowing fish stocks to replenish themselves. They set aside certain areas, such as coral reefs, as protected spots in which fishing is prohibited. When they do fish, these traditional fishers primarily use hook-and-line methods, catching only what they need to feed themselves and their communities.
Traditional Polynesian cultures of the South Pacific have also always relied on the ocean’s resources. Their most common historical fishing practices were hook and line, spearfishing, and cast nets. Hooks constructed of bone, shell, or stone were designed to catch specific species. Fishers would also craft 2-meter (6-foot) spears. They would dive underwater or spear fish from above, again targeting specific animals. Cast nets were used by fishers working individually or in groups. The nets could be cast from shore or canoes, catching groups of fish. All of these methods targeted fish needed for fishers’ families and local communities.
