G5 U5 OVRGRADe 5 UnIT 5 oVeRVIeWLiving Resources of the oceanIntroductionLiving marine resources are vital components of human life. In fact, most living organisms caught in oceansare harvested for human consumption, while other marine materials are used to make products ranging fromsponges to cosmetics. It is important to manage how we take and use the living resources of the ocean to ensurepopulations of these vital stocks remain at harvestable levels. Although estimated seafood consumption numbersare low in comparison to other foods consumed worldwide, their nutritional value is substantially higher. Mostmajor fisheries occur in shallow, near shore waters, while larger or migratory species are more commonly foundin open-ocean fisheries. Marine food chains and webs are complex and fragile. Over-fishing and water pollutioncan cause disruptions in these food chains resulting in reductions in ocean fish stocks.In this unit, students are initially introduced to seafood sold in Hawai‘i. They consult newspaper seafoodadvertisements to define and identify the different types of seafood consumed by islanders.Students review the role of decomposers in marine ecosystems, and construct diagrams linking decomposersto producers and consumers in food chains and webs, noting that decomposers help recycle the energy thatis available in ecosystems. Students investigate what happens to the cycle of matter and flow of energy whenhumans are introduced into the food chain. They also consult United States Department of Agriculture’s(USDA) dietary guidelines to investigate the benefits and potential hazards of eating seafood.The unit wraps up with a student introduction to fisheries. They will learn that the National Oceanic andAtmospheric Administration (NOAA) is the organization that determines and manages fisheries. One of theways NOAA manages fisheries is by putting rules, laws or methods in place. The students will participate ina hands-on activity that shows them how the “capture and recapture” method works.1

The footnotesrefer to the references found in the Science Background for the Teacher Bibliography at the end of this section.What are living marine resources?1 (Lesson 1)The world’s oceans are composed of both physical and biological components. The physical components include all of thenon-living structures and processes, such as rocks, sand, and mud on the sea floor; salts, oxygen, and nutrients dissolvedin the water; and waves, currents, and light that affect the distribution of organisms. The biological components includeall of the living organisms in the oceans, ranging from microscopic bacteria to giant fish and mammals, such as sharksand whales. It is the biological component of our oceans that comprise our living marine resources. Living marineresources include all of the organisms that are utilized by humans, such as for harvesting or recreational uses. Mostof the organisms are harvested for human consumption, but they also provide many other products and materials. Forexample, marine chemists extract compounds from marine organisms, such as sponges and algae, for use in products,such as drugs and cosmetics. Many people use living marine resources for sport fishing, recreational diving, or for homeaquariums. The agricultural industry utilizes living marine resources to produce products, such as fertilizer and animalfeed. Living marine resources are a vital component of human life.What marine resources do we commonly use?2 (Lesson 1)The most common use of our marine resources is for food. In fact, worldwide, 76% of the living marine resourcesharvested in 2002 were for direct human consumption. A wide variety of marine organisms are harvested from the sea forhuman consumption. Examples include seaweeds, jellyfishes, sea urchins, sea turtles, seals, and even polychaete worms.However, the vast majority of the marine resources harvested are fishes, constituting approximately 84% of the total worldcatch. Shellfish, mollusks, and crustaceans are also an important component of the catch. Although the size of the catchfor shellfish is smaller than fishes, the value of the catch is generally greater than that for fishes.Living marine resources constitute only 1% of all the food eaten in the world, with the rest produced on land. However,because seafood is rich in protein, it is a very important food source for human populations. Fishes provide 16% of theanimal protein consumed by humans worldwide. Compared to the thousands of species of fishes and shellfish in the sea,relatively few species represent major fisheries. The largest catches in the world are comprised of small plankton-feedingclupeoid fishes, including herrings, anchovies, sardines, menhadens, and shads. These fishes are eaten fresh, canned,or pickled. Most of the catch for these fishes; however, is ground into fishmeal, a protein supplement used in feed forlivestock, poultry, and farmed fishes. Bottom-dwelling, cold water fishes, such as cods, pollock, haddock, hakes, andwhiting, are another important component of the world catch. The walleye pollock is the largest fishery in U.S. waters.Canned mackerel from areas, such as Japan, South America, and other parts of the world, have become an importantsource of inexpensive protein in some areas. Salmon species are a very valuable catch. Although the numbers caught havebeen in decline, the salmon fishery is still important in the North Pacific in terms of monetary value of the catch. While alarge proportion of the fisheries catch occurs over continental shelves, many important fisheries exist in the open ocean.The most economically important open-ocean fishery is for several species of tuna. Skipjack, yellowfin, albacore, bigeye,and bluefin tunas sell for high prices in world markets. For example, a single large bluefin tuna can sell for more than 100,000. These fishes are eaten either canned, or raw, as sashimi, especially in affluent countries.8

G5 U5 OVRMollusks are the second most valuable group of harvested marine resources after fishes. Cephalopods, such as octopusesand squids, comprise the largest component of the mollusk catch. They are especially prized in Asian and Mediterraneancountries. Other important harvested mollusks include clams, oysters, mussels, scallops, and abalones. Crustaceans, suchas lobster, shrimp, and crab, comprise the other group of shellfishes. These shellfishes are highly prized and consumedworldwide. There are many other groups of marine organisms that are harvested, although they do not contribute much tothe global fisheries production. For example, seaweeds are eaten in many Asian countries. Sea urchins are harvested fortheir gonads, or roe, which are eaten raw. There are traditional fisheries for marine mammals, such as seals and whales,in the Arctic, North Atlantic, West Indies, and the South Pacific. Marine mammals are now protected under the MarineMammal Protection Act and can no longer be caught. Marine mammals are important components of a healthy andbiologically diverse ecosystem. Overfishing or killing of any species can be devastating to an entire ecosystem. Green seaturtles (honu), now a protected species, historically were part of the diet of many Pacific Islanders, including the ancientHawaiians. More information on honu can be found /FINAL Green%20Sea%20Turtle.pdf .For a wide range of information on fisheries of the world, see:www.fao.org/fi/website/FIRetrieveAction.do?dom topic&fid 16063 .This website is fairly technical, but has an abundance of information pertaining to aquaculture and fisheries.Where in the marine environment are most living marine resources extracted?3 (Lesson 1)A majority of the world’s major fisheries are located in coastal waters. Coastal waters lie over the continental shelf. Dueto higher nutrient concentrations, primary production is greater over the continental shelf as compared to open-oceanwaters. The greater amount of primary production supports a larger amount of life. The waters over continental shelvesare relatively shallow, making it easier to harvest bottom-dwelling, or demersal, species. However, fisheries over thecontinental shelf also include pelagic animals, such as tunas, squids, and other organisms. Coastal fisheries are particularlysignificant where the continental shelf is wide, such as the Grand Banks of Newfoundland, the North Sea, and the BeringSea. Larger fisheries are also likely to occur along the coasts of indust
