Knowledge
Aquaculture Knowledge
A comprehensive technical knowledge system covering the science, engineering, biology, production and future of aquaculture.
Domain 01
Foundations
What aquaculture is, the systems it is practised in, the species it works with and the animal itself.
- 01
Aquaculture Fundamentals
What aquaculture is, the forms it takes and the variables that decide whether it works.
11 topics
- 02
Aquaculture Systems
The families of culture system, what each one controls, and how to choose between them.
11 topics
- 03
Species Knowledge
How to read a species as a set of requirements, and how that reading decides the whole farm.
11 topics
- 04
Fish Biology
The physiology behind every water quality limit, feeding decision and stress response on a farm.
11 topics
Domain 02
Production
The production chain from broodstock and seed through nursery and grow-out to the feed that drives it.
- 05
Hatchery and Seed Production
Broodstock, spawning, incubation and larval rearing — the stage where survival is decided.
11 topics
- 06
Nursery Management
The intermediate phase that turns fragile hatchery output into stock a grow-out unit can use.
11 topics
- 07
Grow-Out Farming
The long feeding phase where most of the biomass, nearly all of the feed cost and the margin are decided.
11 topics
- 08
Feed and Nutrition
What farmed aquatic animals require, how feeds are formulated to deliver it, and why feeding is the largest lever on both cost and water quality.
11 topics
Domain 03
Water and Health
The water the animal lives in, the diseases that reach it, the barriers that keep them out and the genetics behind resilience.
- 09
Water Quality
The chemistry the animals live inside, how each parameter is generated and removed, and why they cannot be managed one at a time.
11 topics
- 10
Fish Health and Disease
How disease arises from the interaction of host, pathogen and environment, and how a farm builds diagnosis and response into normal operation.
11 topics
- 11
Biosecurity
The system of barriers and procedures that keeps pathogens out of a farm, contains them if they arrive, and prevents their spread onward.
11 topics
- 12
Breeding and Genetics
How genetic improvement works in aquatic species, what a breeding programme actually requires, and why most farms are consumers rather than operators of one.
11 topics
Domain 04
Farming Systems
Six ways of holding water and animals, each with a different exchange of control, capital and risk.
- 13
RAS Aquaculture
Recirculating systems: the treatment loop that replaces the river, the unit processes it is built from, and the engineering discipline it demands.
11 topics
- 14
Biofloc Technology
Growing a managed microbial community in the culture water so that waste nitrogen is converted in place.
11 topics
- 15
Pond Aquaculture
The earthen pond as a production system: how its soil, water and natural productivity are managed.
11 topics
- 16
Cage Aquaculture
Farming inside an existing water body, where the environment is borrowed rather than built.
11 topics
- 17
Raceway Systems
Flow-through channels that trade a large continuous water requirement for simplicity and control.
11 topics
- 18
Aquaponics
Coupling fish culture with hydroponic plant production so that dissolved waste becomes a crop.
11 topics
Domain 05
Aquatic Environments
Marine, brackishwater, freshwater and coldwater production, and what the water itself dictates.
- 19
Marine Aquaculture
Farming in full-strength seawater, where the chemistry, the species and the exposure are all different.
11 topics
- 20
Brackishwater Aquaculture
Farming in the zone between river and sea, where salinity moves and the site is the design.
11 topics
- 21
Freshwater Aquaculture
Carps, catfish and tilapia in inland ponds — the largest and most accessible part of the sector.
11 topics
- 22
Coldwater Aquaculture
Trout and hill-stream species in fast, cold, oxygen-rich water, where flow is the whole design.
11 topics
Domain 06
Specific Production
Two production types whose biology and economics diverge far enough from finfish to need their own treatment.
Domain 07
Future Aquaculture
Sustainability, engineering, automation and intelligence, and the economics that decide what gets built.
- 25
Sustainable Aquaculture
Producing at a rate the water, the feed supply and the surrounding system can carry indefinitely.
11 topics
- 26
Aquaculture Engineering
Tanks, pumps, pipework, aeration and structures — the physical plant that holds a biological process together.
11 topics
- 27
Automation and AI
Sensing, control, data and machine learning applied to farms — what the technology can do, and what it cannot.
11 topics
- 28
Aquaculture Economics
Cost structure, working capital, risk and the arithmetic that decides whether a technically sound farm is also viable.
11 topics
Domain 08
Value and Research
What happens to the animal after harvest, and where the field's open questions are.
