The name shellfish is misleading because they are not actually fish
Despite the name, shellfish are not a kind of fish, but are simply water-dwelling animals.

Shellfish Association of Great Britain
The Shellfish Association of Great Britain (SAGB) is a historic association that was founded as the Oyster Merchants’ and Planters’ Association in 1903, it was renamed the SAGB in 1969. They cover a wide range of topics within the shellfish industry, from trading to advice on nutritional standards and also the sustainability of the industry. The SAGB is the Shellfish industry’s trade body with the director and staff based at Fishmongers’ Hall which is also home to the Worshipful Company of Fishmongers and can be found in the City of London. The SAGB consists of a wide range of members located within the Shellfish farming and fishing industry, within commercial companies and traders of Shellfish products, the Seafish Industry Authority and the major Sea Fisheries Committees.
Shellfish
Shellfish is a culinary and fisheries term for exoskeleton-bearing aquatic invertebrates used as food, including various species of molluscs, crustaceans, and echinoderms. Although most kinds of shellfish are harvested from saltwater environments, some kinds are found in freshwater. In addition, a few species of land crabs are eaten, for example "Cardisoma guanhumi" in the Caribbean. Despite the name, shellfish are not a kind of fish, but are simply water-dwelling animals. Many varieties of shellfish (crustaceans in particular) are actually closely related to insects and arachnids, making up one of the main classes of the phylum Arthropoda.
Fish as food
Many species of fish are consumed as food in virtually all regions around the world. Fish has been an important source of protein and other nutrients for humans from time immemorial. In culinary and fishery contexts, "fish" may include shellfish, such as molluscs, crustaceans and echinoderms. English does not distinguish between "fish" as an animal and the food prepared from it, as it does with "pig" vs. "pork" or "cow" vs. "beef". Some other languages do, as in the Spanish " versus ". The modern English word for fish comes from the Old English word "fisc" (plural: "fiscas") which was pronounced as it is today.
Aquaculture
Aquaculture is the farming of fish, crustaceans, molluscs, aquatic plants, algae, and other aquatic organisms. Aquaculture involves cultivating freshwater and saltwater populations under controlled conditions, and can be contrasted with commercial fishing, which is the harvesting of wild fish. It is less commonly spelled aquiculture), and is also known as aquafarming. Mariculture refers to aquaculture practiced in marine environments and in underwater habitats. According to the Food and Agriculture Organization (FAO), aquaculture "is understood to mean the farming of aquatic organisms including fish, molluscs, crustaceans and aquatic plants.
Harmful algal bloom
A harmful algal bloom (HAB) are organisms that can severely lower oxygen levels in natural waters, killing marine life. Some HABs are associated with algae-produced toxins. Blooms can last from a few days to many months. After the bloom dies, the microbes which decompose the dead algae use up even more of the oxygen, which can create fish die-offs. When these zones of depleted oxygen cover a large area for an extended period of time, they are referred to as dead zones, where neither fish nor plants are able to survive. HABs are induced by an overabundance of nutrients in the water. The two most common nutrients are fixed nitrogen (nitrates, ammonia, urea) and phosphate.
Maritime history of California
In the California coast, the use of ships and the Pacific Ocean has historically included water craft (such as dugouts, canoes, sailing ships, and steamships), fisheries, shipbuilding, Gold Rush shipping, ports, shipwrecks, naval ships and installations, and lighthouses. The maritime history of California can be divided into several periods: the Native American period; European exploration period from 1542 to 1769; the Spanish colonial period, 1769 to 1821; the Mexican period, 1821 to 1847; and United States statehood period, which continues to the present day. In the northwest coast of California near the redwood forests several Indian tribes developed large dugout canoes they used for fishing, trade and warfare.
Seafood
Seafood is any form of sea life regarded as food by humans. Seafood prominently includes fish and shellfish. Shellfish include various species of molluscs, crustaceans, and echinoderms. Historically, sea mammals such as whales and dolphins have been consumed as food, though that happens to a lesser extent in modern times. Edible sea plants, such as some seaweeds and microalgae, are widely eaten as seafood around the world, especially in Asia (see the ). In North America, although not generally in the United Kingdom, the term "seafood" is extended to fresh water organisms eaten by humans, so all edible aquatic life may be referred to as seafood.

That's a lovely name you got-Shellfish.Since they are no fish ,what are they then?

Marine life
Marine life, or sea life or ocean life, refers to the plants, animals and other organisms that live in the salt water of the sea or ocean, or the brackish water of coastal estuaries. At a fundamental level, marine life helps determine the very nature of our planet. Marine organisms produce much of the oxygen we breathe. Shorelines are in part shaped and protected by marine life, and some marine organisms even help create new land. Most life forms evolved initially in marine habitats. Oceans provide about 99 percent of the living space on the planet. The earliest vertebrates appeared in the form of fish, which live exclusively in water.
Aquaculture
Aquaculture is the farming of fish, crustaceans, molluscs, aquatic plants, algae, and other aquatic organisms. Aquaculture involves cultivating freshwater and saltwater populations under controlled conditions, and can be contrasted with commercial fishing, which is the harvesting of wild fish. It is less commonly spelled aquiculture), and is also known as aquafarming. Mariculture refers to aquaculture practiced in marine environments and in underwater habitats.

Arthropod
An arthropod (from Greek ἄρθρον "arthron", "joint" and πούς "pous", "foot") is an invertebrate animal having an exoskeleton (external skeleton), a segmented body, and paired jointed appendages. Arthropods form the phylum Euarthropoda, which includes insects, arachnids, myriapods, and crustaceans. The term Arthropoda as originally proposed refers to a proposed grouping of Euarthropods and the phylum Onychophora. Arthropods are characterized by their jointed limbs and cuticle made of chitin, often mineralised with calcium carbonate. The arthropod body plan consists of segments, each with a pair of appendages.
Pain in crustaceans
The question of whether crustaceans experience pain is a matter of scientific debate. Pain is a complex mental state, with a distinct perceptual quality but also associated with suffering, which is an emotional state. Because of this complexity, the presence of pain in an animal, or another human for that matter, cannot be determined unambiguously using observational methods, but the conclusion that animals experience pain is often inferred on the basis of likely presence of phenomenal consciousness which is deduced from comparative brain physiology as well as physical and behavioural reactions.
Mollusca
Mollusca is a large phylum of invertebrate animals whose members are known as molluscs or mollusks (). Around 85,000 extant species of molluscs are recognized. The number of fossil species is estimated between 60,000 and 100,000 additional species. Molluscs are the largest marine phylum, comprising about 23% of all the named marine organisms. Numerous molluscs also live in freshwater and terrestrial habitats. They are highly diverse, not just in size and in anatomical structure, but also in behaviour and in habitat. The phylum is typically divided into 9 or 10 taxonomic classes, of which two are entirely extinct.
Ambush predator
Ambush predators or sit-and-wait predators are carnivorous animals or other organisms, such as some nematophagous fungi and carnivorous plants, that capture or trap prey by stealth or by strategy (typically not conscious strategy), rather than by speed or by strength. In animals, ambush predation is characterized by an animal scanning the environment from a concealed position and then rapidly executing a surprise attack. Animal ambush predators usually remain motionless (sometimes hidden) and wait for prey to come within ambush distance before pouncing. Ambush predators are often camouflaged, and may be solitary animals.
Aquatic locomotion
Aquatic locomotion is biologically propelled motion through a liquid medium. The simplest propulsive systems are composed of cilia and flagella. Swimming has evolved a number of times in a range of organisms including arthropods, fish, molluscs, reptiles, birds, and mammals. Swimming evolved a number of times in unrelated lineages. Supposed jellyfish fossils occur in the Ediacaran, but the first free-swimming animals appear in the Early to Middle Cambrian. These are mostly related to the arthropods, and include the Anomalocaridids, which swam by means of lateral lobes in a fashion reminiscent of today's cuttlefish.
