Unit: 2. Aquatic and Land-Based Production
Agribusiness
Learning Outcome: 1. I can understand the morphology and nutritional requirements of different fish species.


Types of fish:
Ornamental Fish:
- Cold water: goldfish or mosquitofish or
- Tropical: cichlids or Siamese fighter fish;- Edible fish: tuna or seabream or tilapia; Pangasius.
Morphology:
- Exterior: fins; head; lateral line; scales;
- Interior: skeleton; swim bladder; heart; gills; brain; reproductive organs.


Nutrients:
- Proteins;
- Carbohydrates;
- Fat;
- Fibre;
- Vitamins: A;B;C;D;E;K
Minerals: calcium; phosphorus; sodium; potassium; iron; zinc.


Life Stages: larva/fry; juvenile; adult; reproductive/broodstock.
Nutritional Requirements: proteins; carbohydrates; fats.
Different fish species: tuna; goldfish.
Learning Outcome: 2. I can care for fish in order to prevent and cure diseases and correct disorders.


Fish diseases:
- Fin rot;
- White spot (ich);
- Fish pop-eye;
- Lateral line disease;
- Parasites: e.g. lice;
- Virus: e.g. nodavirus;
Fish disorders: bloat; genetic disorders caused by inbreeding.




Tank requirements: size; temperature; salinity; pH; filtration (ammonia, nitrite, nitrate); light; aeration; water source; decor;
Cage requirements: size; location; materials used.


Routine tasks: water change; cleaning; feeding; water testing and amendments; record keeping;
Health and Safety: switch off electrical components before cleaning; be aware of sharp edges; wear rubber sole shoes; wash hands; handle chemicals with care.
Learning Outcome: 3. I can describe the main processes of plant physiology.


Structure and Function of plant organs of monocots and dicots: xylem; phloem; roots; leaf.


Plant physiological processes: e.g. transpiration, translocation, photosynthesis, osmosis, germination, tropisms (photo- and geo-), respiration.


Flower control: photoperiodism; vernalisation; artificial lighting; blackouts; heating; cooling.
Learning Outcome: 4. I can cultivate and care for a range of vegetables from field to market.


Types of records: date and field number; type of pathogens; weather condition; pesticide name and active ingredient; nutrient content of fertiliser; quantity/dose of chemical, method of application; type of crop.


Vegetable Species: potatoes or onions.
Symptoms of diseases:
- Potatoes: early blight; late blight;
- Onions: rust; downy mildew;
Symptoms of deficiencies:
- Potatoes: nitrogen; potassium;
- Onions: nitrogen; phosphorus;


Cultural practices: choice of resistant/tolerant propagative material; crop rotation; intercropping; solarisation; traps; field burning; tillage;
Biological practices: biological control; manure;
Chemical practices: sterilisation; pesticides; artificial fertiliser.


Main Factors: species and cultivar; weather conditions, fertility, overall care.


Range of vegetables: e.g. potatoes, spring onions, lettuce, cabbages.
Post-harvest practices: Cleaning; grading; packaging; labelling; storage.
Learning Outcome: 5. I can explain the propagation, care and harvesting requirements for different crops.


Propagation techniques: seeding; grafting; cuttings; runners; bulb; rhizome; division; layering.


Growing objectives: good water drainage; aeration; pathogen/pest free; nutrient dynamics and control.
Growing media: peat; compost; coconut fibre; soil; perlite; vermiculite; rockwool; expanded clay.


Propagation techniques: e.g. seeding, grafting, cuttings, runners, bulb, rhizome, division, layering.
