List of commercially important fish species

List of commercially important fish species is a biology topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand List of commercially important fish species rather than just read about it. In short: This is a list of aquatic animals that are harvested commercially in the greatest amounts, listed in order of tonnage per year (2012) by the Food and Agriculture Organization. Species listed here have an annual tonnage in excess of 160,000 tonnes.

Key takeaways

  • List of commercially important fish species belongs to biology; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect List of commercially important fish species to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of List of commercially important fish species from memory before moving on to harder problems.

Reference excerpt

This is a list of aquatic animals that are harvested commercially in the greatest amounts, listed in order of tonnage per year (2012) by the Food and Agriculture Organization. Species listed here have an annual tonnage in excess of 160,000 tonnes. This table includes mainly food fish species, but also listed are crustaceans (crabs and shrimps), cephalopods (squids and cuttlefishs), bivalves, and a reptile (softshell turtle). Note that Oreochromis niloticus and Penaeus monodon appear twice, because substantial amounts are harvested from the wild as well as being extensively raised through aquaculture.

Summary The 70 wild species shown in this table total 41,925,250 tonnes. Other wild species total 49,410,980 for a world total of 91,336,230 tonnes of wild, captured animals. The 31 cultivated species shown in this table total 45,252,999 tonnes. Other cultivated species total 21,380,254 tonnes for a world total of 66,633,253 tonnes of animals cultivated through aquaculture.

Worked examples

Example 1 — a first encounter with List of commercially important fish species

Start with the simplest possible case. Write down what List of commercially important fish species claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In biology, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to List of commercially important fish species before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about List of commercially important fish species ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of List of commercially important fish species

In research
List of commercially important fish species appears in biology research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses List of commercially important fish species in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
List of commercially important fish species is common in secondary-school and first-year university syllabi. It links to neighbouring topics Commercial fish, Fishing industry, Lists of fishes, so understanding it makes those chapters shorter.
In everyday life
Look for List of commercially important fish species outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
