Practical Fishkeeping

Practical Fishkeeping is a science 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 Practical Fishkeeping rather than just read about it. In short: Practical Fishkeeping (also known as PFK) is a United Kingdom-based aquarium magazine. It is published every four weeks by Warners Publications Plc.

Key takeaways

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

Reference excerpt

Practical Fishkeeping (also known as PFK) is a United Kingdom-based aquarium magazine. It is published every four weeks by Warners Publications Plc. The title covers the entire aquatic market from tropical freshwater and tropical marine fishkeeping throughout the year to small amounts of pond and coldwater fish coverage during the summer months.

History and profile Originally called Pet Fish Monthly, the title launched in April 1966. The title changed its name to Practical Fishkeeping in 1981. The magazine is edited by Nathan Hill, who took on the role as of January 2018. Regular contributing authors include, Nathan Hill, Julian Dignall, Ad Konings, Max Pedley, Ivan Mikolji, Keith Naitby, Chris Sergeant, Tim Smith, Heiko Bleher, Gabor Horvath, Steve Baker, Tristan Lougher, Dave Wolfenden, Bob Mehen and George Farmer. Former editors of the title include Steve Windsor, Nick Fletcher, Karen Youngs, Matt Clarke, Jeremy Gay and Angela Kenny. The headquarters is in Bourne, Lincolnshire. Practical Fishkeeping also has a very successful website, regularly covering fish related news. Until 2018 it also hosted a popular web forum with over 190,000 members. The Forum expanded even further on the printed magazine and the online articles that were found on the main site.

Worked examples

Example 1 — a first encounter with Practical Fishkeeping

Start with the simplest possible case. Write down what Practical Fishkeeping claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, 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 Practical Fishkeeping 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 Practical Fishkeeping 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 Practical Fishkeeping

In research: Practical Fishkeeping appears in science 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 Practical Fishkeeping 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: Practical Fishkeeping is common in secondary-school and first-year university syllabi. It links to neighbouring topics Animal and pet magazines, Fishkeeping, Fishkeeping stubs, so understanding it makes those chapters shorter.
In everyday life: Look for Practical Fishkeeping 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.
