Grade 4

Food production in south africa

Module 25

The fishing industry

When you look at a map of South Africa, you'll see that the sea on three sides borders the country. South Africa has a very long coastline reaching from Alexander Bay in the Northwest to Kosi Bay on the northeasterly coast of KwaZulu-Natal. Many South Africans therefore also make a living from fishing.

FISHING AREAS in South Africa

  • Larger fish like barracuda (snoek) and cob (kabeljou) are caught with hand lines from boats, while other deep-sea types like sardines and hake are caught in nets trailed from behind boats.
  • The sea is a large source of food and approximately 30 000 people annually make a living from the fishing industry in South Africa. Many people also angle for sport. Besides the sea fish that are caught, smaller quantities of fresh water fish also appear in delicious dishes on many tables.

Can you find three reasons for the importance of the fishing industry to south africa in the above paragraphs?

Activity 1

To fill in as many examples as possible in a table [lo 1.2]

Fish as Food
Sea fish Fresh water fish
Activity 2: To complete a flow diagram on the processing of fish [LO 1.1]
  • Study the following sketches and complete the diagram.

Processing of fish

(flow diagram)


Learning outcome 1: geographical enquiry

The learner will be able to use enquiry skills to investigate geographical and

environmental concepts and processes.

Assessment standard

We know this when the learner:

1.1 identifies information from various sources (maps, atlases, books) [finds sources].

1.2 organises information under given headings [works with sources].


The processing of fish

  • Fish is caught in different ways e.g. dragnets; hand lines.
  • Fish is weighed, cleaned and sold.
  • Fish is transported to factories (industrial) where it is processed.
  • Fish is processed to products such as fish oil, fishcakes, fish fingers, and fresh fish for frying or braaiing.

Yes, Nanotechnology has a very fast field of applications and their is always something new to do with it...

good afternoon madam
what is system testing
what is the application of nanotechnology?
In this morden time nanotechnology used in many field . 1-Electronics-manufacturad IC ,RAM,MRAM,solar panel etc 2-Helth and Medical-Nanomedicine,Drug Dilivery for cancer treatment etc 3- Atomobile -MEMS, Coating on car etc. and may other field for details you can check at Google
anybody can imagine what will be happen after 100 years from now in nano tech world
after 100 year this will be not nanotechnology maybe this technology name will be change . maybe aftet 100 year . we work on electron lable practically about its properties and behaviour by the different instruments
name doesn't matter , whatever it will be change... I'm taking about effect on circumstances of the microscopic world
how hard could it be to apply nanotechnology against viral infections such HIV or Ebola?
silver nanoparticles could handle the job?
not now but maybe in future only AgNP maybe any other nanomaterials
I'm interested in Nanotube
this technology will not going on for the long time , so I'm thinking about femtotechnology 10^-15
can nanotechnology change the direction of the face of the world

At high concentrations (>0.01 M), the relation between absorptivity coefficient and absorbance is no longer linear. This is due to the electrostatic interactions between the quantum dots in close proximity. If the concentration of the solution is high, another effect that is seen is the scattering of light from the large number of quantum dots. This assumption only works at low concentrations of the analyte. Presence of stray light.

the Beer law works very well for dilute solutions but fails for very high concentrations. why?
