What Is seafood..?? Seafood is any form of sea life regarded as food by humans, prominently including fish and shellfish. Shellfish include various species of mollusks, crustaceans, and echinoderms. Seafood comprises all bony fishes and the more primitive sharks, skates, rays, sawfish, sturgeons, and lampreys; crustaceans such as lobsters, crabs, shrimps, prawns, and crayfish; mollusks, including clams, oysters, cockles, mussels, periwinkles, whelks, snails, abalones, scallops, and limpets; the cephalopod mollusks
Fish Fish are gill-bearing aquatic craniate animals that lack limbs with digits It is an important resource for humans worldwide, especially as food. They are abundant in most bodies of water. They can be found in nearly all aquatic environments, from high mountain streams
Few things we should know about fishes It is one of the most nutritious and easily digestible foods in our diet. Available in a wide variety and can be cooked in many ways and in a short time . The fibers are thinner and smaller than the meat so it is more sensitive. Cooked fish should be handled very carefully because it breaks very easily. We avoid overcooking them because they go too "dry" and become indigestible.
Types of fishes There are mainly two types of fish based on their origin : Fish of salt water that live in the seas . Fish of fresh water that live in lakes, rivers, dams, or aquariums.
Saltwater fish Saltwater fish , also called marine fish, are fish that live in ocean water. It can swim and live alone or live in a large group together, called a school of fish. They are very popular among deep sea fishermen and aquariums all over the country.
What kind of fish are saltwater fish Many kinds of fish live in the salty water of the oceans. A fish's kidney keeps the proper balance of salt in its body. Popular saltwater fish are bluefish, cod, flounder, striped bass (also found in freshwater), sea trout, tarpon, tuna, halibut, rockfish, sea perch, lingcod, and yellowtail.
the most common saltwater fish Flame Angelfish (Centropyge loricula) Maroon Clownfish (Premnas biaculeatus) Coral Beauty (Centropyge bispinosa) Six-line Wrasse (Pseudocheilinus hexateaenia) Tomato Clownfish (Amphiprion frenatus) Royal Gramma (Gramma loreto) Pajama Cardinalfish (Sphaeramia nematoptera)
What Do saltwater fish eat? In a saltwater aquarium, many fish (even carnivores) can be weaned off of their usual fare in the wild and coaxed into taking hand fed foods such as pellets and flakes with their protein requirements being supplemented with frozen foods such as shrimp, fish , squid, or krill
How many saltwater fishes are there in the world..?? Scientists estimate that there are almost 22,000 fish species in the world . The most fruitful potential areas for discovery include the tropics, deep seas and southern hemisphere .
How do salt water fish live Some fish that only live in a saltwater environment, such as tuna, drink the very, very salty seawater . Their kidneys are specially adapted to excrete lots of salt, and even their gills can excrete salt in this way so that they keep their blood salinity levels at an optimum
Why do saltwater fish need salt..?? The water in saltwater fish is continuously pulled out of their bodies into the surrounding water because their bodily fluids have lower concentrations of salt. It's important to note that all fish require some level of salt in their bodies to be healthy, but like humans, too much or too little can make them sick.
Why saltwater fish cannot survive in freshwater..?? Saltwater fish can't survive in freshwater because their bodies are highly concentrated of salt solution (too much for freshwater). The water would flow into their body until all their cells accumulate so much water that they bloat and die eventually.
WHY DON’T SALTWATER FISH TASTE SALTY..?? Marine fish do not taste salty because get rid of the excess salt they ingest in order to maintain a balance of electrolytes in the body.
Freshwater fish Freshwater fish are those that spend some or all of their lives in fresh water, such as rivers and lakes, with a salinity of less than 0.05 %. These environments differ from marine conditions in many ways, the most obvious being the difference in levels of salinity
How to identify fresh fish Eyes : Shiny, bright, clear, open and bulging . Color : Be lively . Flesh : Be firm, stuck in the bones and elastic. When the finger pressed does not form cavity . Fins : Be hard and not easily moved . Scales : Be hard and not easily moved . Gills : To have a pink or red color, not dark . Tail : When you hold the fish between two fingers, the tails are up and do not bend their body, but stays in a straight line.
Types of freshwater fishes Catfish. Characins and other characiformes. Cichlids . Cyprinids . Loaches and related cypriniformes. Live-bearers and killifish. Labyrinth fish. Rainbow fish .
How many freshwater fishes are there..? It has been estimated that the total number of all fishes is 32,500 species. Considering that freshwater may constitute less than 0.3% of available global water, it is remarkable that there are more than 15,000 freshwater fish species
Most common freshwater fish There are more than 800 known freshwater fish species in North America alone. Worldwide , the number is over 10,000 species. Some species of freshwater fish, such as salmon and trout, are called anadromous . They hatch in fresh water , head out to sea, where they live until they return to fresh water to reproduce.
Most dangerous freshwater fish Vampire fish prey primarily on smaller fish, especially piranhas, which they impale with their long, sharp fangs . The intimidating teeth can grow up to six inches long . Perhaps the most feared freshwater species of all, candiru are parasitic catfish in the family Trichomycteridae.
MERCURY IN A FISH Fish and shellfish concentrate mercury in their bodies, often in the form of methylmercury , a highly toxic organomercury compound. Fish products have been shown to contain varying amounts of heavy metals, particularly mercury and fat-soluble pollutants from water pollution.
Do freshwater fish have mercury..?? The freshwater fish most likely to contain harmful amounts of mercury include smallmouth bass, walleye, largemouth bass, lake trout and Northern pike.
MERCURY LEVELS IN COMMERCIAL FISH AND SEAFOOD SPECIES MERCURY CONCENTRATION MEAN (PPM) MERCURY CONCENTRATION MAX (PPM) TILAPIA 0.013 0.084 SALMON (CANNED) 0.014 0.086 ANCHOVIES 0.016 0.049 SALMON (FRESH/FROZEN) 0.022 0.19

Most of the popular species of fish and shellfish consumed in the U.S. have been shown to have low mercury levels . Seafood choices that are very low in mercury include: salmon, sardines, pollock, flounders, cod, tilapia, shrimp, oysters, clams, scallops and crab.
What kinds of fish does not have mercury That amounts to about 2 to 3 servings of fish per week, which can be eaten in place of other types of protein . Make sure to choose a variety of fish lower in mercury, such as salmon, tilapia, shrimp, tuna (canned-light), cod, and catfish. Consumption of white (albacore) tuna should not exceed 6 ounces per week.

shellfish Shellfish is a colloquial and fisheries term for exoskeleton-bearing aquatic invertebrates used as food, including various species of mollusks, crustaceans, and echinoderms. Although most kinds of shellfish are harvested from saltwater environments, some are found in freshwater
difference between fish and shellfish Seafood includes fish (like tuna or cod) and shellfish (like lobster or clams). Even though they both fall into the category of "seafood," fish and shellfish are biologically different . C rustaceans , like shrimp, crab, or lobster. mollusks, like clams, mussels, oysters, scallops, octopus, or squid.
Types of shellfish They can be divided into two groups: C rustaceans and M ollusks . Crustaceans include shrimp, crayfish, crab, and lobster, while clams, scallops, oysters, Mussels are examples of mollusks . Most shellfish live in saltwater, but the name also refers to species found in freshwater
Crustaceans Crustaceans form a large, diverse arthropod taxon which includes such familiar animals as crabs, lobsters, crayfish, shrimps, prawns, krill, woodlice, and barnacles.
CHARACTERISTC OF Crustaceans A hard exoskeleton made of calcium - no internal skeleton. The head has two compound eyes, two pairs of antennae, and three pairs of mouthparts. A pair of green glands excrete wastes near the base of antennae. The abdominal segments have swimmerets (swimming legs)
MAIN FEATURES OF Crustaceans The four main features of a crustaceans body are : Two distinct body sections, a hard exoskeleton, two pairs of antennae, & one pair of appendages on each segment.
Where do crustaceans live? Most crustaceans live in the ocean—although some species live in freshwater, and woodlice and a few crabs live on land . Prawns and shrimp swim freely in open water . Barnacles live attached to rocks, harbor walls, or the sides of ships.
Do crustaceans have organs? Two different excretory organs are found among crustaceans: the antennal gland and the maxillary gland . In most adult crustaceans only one or the other gland functions .
What is the largest crustacean? The world largest crustacean is the Japanese Spider Crab. It can weigh up to 20kg (45 lb). If it stretches out its legs, they can reach up to 4 metres (13 feet ) from tip to tip!
How do crustaceans reproduce? Most crustaceans reproduce sexually with a separate male and female . Most females lay eggs that hatch into free-swimming larvae, though some crustaceans such as shrimps hatch into tiny versions of adults.
WHAT DOES Crustaceans EAT..?? Many crustaceans are scavengers, feeding on scraps and dead creatures. Crabs , shrimp, and prawns search for food mainly at night and hide in crevices by day. Some crabs and lobsters are active predators, seizing prey in their powerful claws. Barnacles filter tiny creatures from the water using their hairy legs.
Do crustaceans eat coral? Shrimps , crabs, lobsters, and other crustaceans find protection from predators in crevices or between coral branches . Crustaceans are also predators. The coral crab crushes sea urchins and clams with its strong claws.
MOLLUSKS Mollusca is the second-largest phylum of invertebrate animals after the arthropoda. The members are known as mollusks or mollusks . Around 85,000 extant species of mollusks are recognized. The number of fossil species is estimated between 60,000 and 100,000 additional species
TYPES OF MOLLUSKS There are several subgroups of mollusks , but only three major ones: - The Gastropods , made up mostly of snails and slugs. T he Bivalves , a group including clams, scallops, mussels, and oysters. The Cephalopods , a group including octopus and squid.
characteristics of mollusks Unsegment soft body with bilateral symmetry. Presence of an internal or external shell. A toothed tongue (made mostly of chitin) called the radula . A mantle which is a fold in the body wall that lines the shell.
What foods are mollusks? Mollusks include many of the most important seafood's such as abalone, clams, mussels, octopus, oysters, squid, and scallops as well as terrestrial snails . Marine mollusks and crustacean (shrimps, prawns, crabs, crayfish and lobsters) are both known as shellfish.
How do mollusks reproduce? Mollusks reproduce sexually. Slugs and snails are hermaphrodites (possessing both male and female organs), but they must still mate to fertilize their eggs. Most aquatic mollusks lay eggs that hatch into small, free-swimming larvae called veliger.
example of a mollusk without a shell Bivalves are mollusks with two shells such as clams and oysters. Univalves are animals with one shell such as a snail. Mollusks without shells include squid, banana slugs, and octopi
