Inland saline aquaculture

Inland saline aquaculture 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 Inland saline aquaculture rather than just read about it. In short: Inland saline aquaculture is the farming or culture of aquatic animals and plants using inland (i.e. non-coastal) sources of saline groundwater rather than the more common coastal aquaculture methods. As a side benefit, it can be used to reduce the amount of salt in underground water tables, leading to an improvement in the surrounding land usage for agriculture.

Key takeaways

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

Reference excerpt

Inland saline aquaculture is the farming or culture of aquatic animals and plants using inland (i.e. non-coastal) sources of saline groundwater rather than the more common coastal aquaculture methods. As a side benefit, it can be used to reduce the amount of salt in underground water tables, leading to an improvement in the surrounding land usage for agriculture. Due to its nature, it is only commercially possible in areas that have large reserves of saline groundwater, such as Australia.

Systems

Extensive culture Extensive culture aquaculture systems are simple and with low levels of intervention. An example of this would be a salty dam, lake or pond stocked with trout, where no food is needed to be added as the fish can feed off what naturally occurs in the water. While they required little capital investment or management time, their productivity is relatively low.

Intensive culture Intensive culture requires more capital outlay and greater management time. Often they use purpose-built facilities (e.g. tanks), artificial food and aeration and constant monitoring of water quality. It has much higher productivity rates, but associated high levels of feeding, labour, water pumping and capital costs.

Semi-intensive culture Semi-intensive culture is in between extensive and intensive culture. It may range from adding some artificial feed to an extensive system or some aeration and waste management. Costs rise as more inputs are added.

Suitable species

Fish Rainbow trout - robust, fast growth, require low water temperatures, may be limited to winter production Brown trout - robust, fast growth, require low water temperatures, may be limited to winter production Barramundi - needs higher temperatures, tolerant in a large range of salinity levels Macquarie perch - wide tolerance over range of salinity and water quality levels, not suitable for commercial quantities Silver Perch - suitable for extensive and intensive systems, prefers warmer water Snapper

Other species Crustaceans - brine, shrimp, prawns - these can be included as part of a wastewater treatment program as some have the capacity to quickly clean water Molluscs - mussels Algae - both unicellular and "seaweeds" can be used to extract a range of high-value products, including pharmaceutical chemicals.

Mixing species

Chain system Some inland aquaculture systems involve using a range of separated species to increase its productivity. An example of this would be where water is used to culture a fish specifies, which is then diverted to tanks of shellfish which feed on the fine particles left by the fish, which then is diverted to algae species which remove the dissolved nutrients, and then last of all the water is sent to a horticultural system.

Polyculture

Separate from this type of system is polyculture, where two or more species are cultured in the same water, possibly multiple fish species or a fish and mollusc species.

Worked examples

Example 1 — a first encounter with Inland saline aquaculture

Start with the simplest possible case. Write down what Inland saline aquaculture 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 Inland saline aquaculture 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 Inland saline aquaculture 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 Inland saline aquaculture

In research: Inland saline aquaculture 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 Inland saline aquaculture 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: Inland saline aquaculture is common in secondary-school and first-year university syllabi. It links to neighbouring topics Aquaculture, so understanding it makes those chapters shorter.
In everyday life: Look for Inland saline aquaculture 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.
