Mariculture: Farming the Fruits of the Sea — Frances King Koch
Published by Franklin Watts/Scholastic, 1992.
You probably know that the shrimp you eat come from the ocean, but you may not know that many shrimp are raised on special sea farms. With color photographs and drawings, this book from the New England Aquarium explores mariculture, the practice of hatching and raising living things that come from the ocean. The history of mariculture, which has been around for thousands of years, is presented, along with a look at the way sea farming is practiced today around the world. The demand is growing for seafood, algae, and seaweed for both food and industrial uses. In fact, mariculture may provide a solution to the problem of world hunger. At the same time, it could prevent the overharvesting of sea creatures in their natural environment.
Salmon — Deborah Hodge
Published by Kids Can Press, 2002.
While it may not seem as though it’s the most romantic or beautiful of the fishes that inhabit our seas, the salmon is one of the most interesting. Every year, thousands of salmon struggle to leave their saltwater homes to return to the freshwater where they were born. They struggle to swim upstream, against the current, becoming battered and bruised during the long hard journey, so that they can lay their eggs—as many as eight thousand eggs! In this book, color illustrations depict both Pacific and Atlantic salmon and follow the salmon through its life cycle from eggs to alevin, fry, smolts, adults, and finally spawners.
Salmon — Ron Hirschi
Published by Carolrhoda Books/Lerner Publishing, 2001.
Some of you may know salmon as a tasty dinner, but did you know that salmon, as a fish, can live in both salt and freshwater? A fish so determined to get to his spawning grounds that it swims upriver for miles every year? Bears, sea lions, and people depend heavily on this fish for food. This book tells where and how salmon live with pictures and detailed explanations.
aquaculture The science, art, and business of cultivating marine or freshwater food fish and or shellfish, such as oysters, clams, salmon, and trout, under controlled conditions.
kelp A type of large, brown seaweed that is found in colder ocean regions. Some species of kelp can grow to over 200 feet (61 meters) long.
