Fish & Seafood Chapter 3 Quiz

Explanation
Fresh shrimp typically has a shelf life of a few days. This is because seafood, including shrimp, is highly perishable and can spoil quickly if not stored properly. Factors such as temperature, handling, and storage conditions can affect the shelf life of fresh shrimp. It is recommended to consume fresh shrimp within a few days of purchase to ensure its quality and freshness.

Explanation
Shell-off shrimp should not be stored in flaked ice because the ice can cause the shrimp to become waterlogged, resulting in a loss of texture and flavor. It is recommended to store shell-off shrimp in airtight containers or bags in the refrigerator to maintain their freshness and quality.

Explanation
The statement suggests that slimy or yellowing flesh in shrimp is acceptable. However, this is not true. Slimy or yellowing flesh in shrimp is a sign of spoilage and is not safe to consume. Therefore, the correct answer is False.

Explanation
Green, headless shrimp is the most widely sold market form of shrimp in the world. This is because green, headless shrimp are easier to handle and cook compared to whole, head-on shrimp. Additionally, removing the head makes the shrimp more visually appealing to consumers. Peeled and deveined shrimp are also popular, but they require more processing and are therefore less commonly sold.

Explanation
The statement is true because peeled shrimp are indeed green headless shrimp with the shell and tail removed.

Explanation
The whole squid contains the head, tentacles, ink sac, mantle, and quill or pen. The head is where the squid's brain and sensory organs are located. The tentacles are used for capturing prey and bringing it towards the mouth. The ink sac is responsible for producing ink, which the squid releases as a defense mechanism. The mantle is a muscular covering that encloses the squid's internal organs. The quill or pen is a hard structure made of chitin that supports the squid's body.

Explanation
Fresh squid freezes well because squid has a high water content and freezes easily without losing its texture or flavor. Freezing squid also helps to preserve its freshness and prevents spoilage. When properly frozen, squid can be stored for an extended period of time without compromising its quality.

Explanation
Live lobsters should not be submerged in fresh water. Lobsters are saltwater creatures and they require a specific salinity level to survive. Submerging them in fresh water can cause stress and even death for the lobsters. Therefore, the statement is false.

Explanation
Wet scallops are soaked in a water bath containing sodium tripolyphosphate, which helps them retain 25% of moisture. This moisture retention can help to keep the scallops juicy and tender during cooking. Additionally, the sodium tripolyphosphate brightens the color of the scallops, making them more visually appealing. It also extends the shelf life of the scallops, allowing them to stay fresh for longer periods of time. However, one downside is that wet scallops can become extremely difficult to cook and become rubbery if not handled properly.

Explanation
Mussels have a beard that should be removed. The beard is a fibrous structure called a byssus, which is used by mussels to attach themselves to surfaces. It is located near the hinge of the shell and can be tough and stringy. To prepare mussels for cooking, the beard needs to be removed as it can be unpleasant to eat.

Explanation
The statement is stating that the queen conch is a warm-water species of mollusk. This means that the queen conch is typically found in warm waters rather than cold waters. Therefore, the correct answer is true.

Explanation
A whole lobster yields approximately 20% of its total body weight in edible meat. This means that if a lobster weighs 1 pound, there will be approximately 0.2 pounds of meat that can be consumed. Lobsters have a hard exoskeleton and a significant portion of their weight is made up of shells and other inedible parts, resulting in a relatively low yield of edible meat.

Explanation
The correct answer is "Clawless" because spiny lobsters do not have large claws like other lobsters. Instead, they have long spiny antennae and a hard carapace. This adaptation allows them to rely on their speed and agility to escape predators rather than using their claws for defense.

Explanation
Tomalley is a substance found in lobsters that serves as both a liver and a pancreas. It is a greenish or yellowish gooey substance located in the body cavity of the lobster. Tomalley plays a crucial role in the lobster's digestive system, producing enzymes that aid in the breakdown of food. It also stores and metabolizes nutrients, acting as both a liver and a pancreas. Tomalley is often considered a delicacy and is used in various culinary preparations.

Explanation
The stone crab species is caught for its edible claws. Stone crabs are known for their large and delicious claws, which are a delicacy in many seafood dishes. The claws are harvested and the crabs are released back into the water, as they have the ability to regenerate their claws. This sustainable practice ensures a continuous supply of stone crab claws for consumption.

Explanation
Lobsters can live out of water for several days. Although they are primarily aquatic creatures, they have the ability to survive on land for a limited period of time. This is because lobsters have gills that allow them to extract oxygen from the water, but they can also absorb oxygen from the air through their gills. However, they still need to be kept moist to prevent dehydration and ensure their survival. Therefore, while they can survive for several days out of water, it is important to return them to their natural habitat as soon as possible.
