Area = Length x Breadth
Area = 130 x 70

A fish pond is an artificial lake or retention basin stocked with fish and used in aquaculture for fish farming, recreational fishing, or ornamental purposes.
(1aiii)
(i) Suitable land area
(ii) Availability of water supply
(iii) Quality of water
(iv) Soil characteristics
(1bi)
(i) Selection of ingredients
(ii) Grinding
(iii) Feed formulation
(iv) Mixing
(v) Pelleting
(1bii)
(i) De-weeding:
This is the removal of weeds from the field. It is an effective pre-harvesting method of crop protection and crop production management.
(ii) De-slitting:
This is the removal of fine silt and sediment that has collected in a river to restore its natural capacity, without widening or deepening the river.

(2ai)
(i) It serves as sources of food
(ii) It serves as sources of fuel
(iii) It provides job opportunities
(iv) It reduces trade deficit
(v) It reduces wild stock pressure
(vi) It helps in biodiversity conservation
(2aii)
Clarias gariepinus species are cultured in areas with a tropical climate. It is a hardy fish that can be densely stocked in low oxygen waters making it ideal for culture in areas with a limited water supply. Its air-breathing ability, high fecundity, fast growth rate, resistance to disease and high feed conversion efficiency makes clarias gariepinus the culturable.

Artificial breeding is the use of technologies such as artificial insemination and embryo transfer.
(4aii)
(i) Both natural selection and artificial selection are two methods involved in the breeding of organisms.
(ii) Both natural selection and artificial selection allow selected characters to pass to the next generation.
(4aiii)
(i) Creation of genetic variation by various means (ii) Selection
(iii) Evaluation and Release as a variety
(iv) Seed multiplication and distribution among farmers.

ORGANIC FERTILIZER
(i) Compost
(ii) Manure
INORGANIC FERTILIZER
(i) Phosphorous Fertilizers
(ii) Nitrogen Fertilizers
RECOMMEND VALUES OF APPLICATION FOR ORGANIC
• To be applied in bulk, more quantity has to be supplied to fulfill recommended rate of NPK application. For example, if we need to apply 120 kg N per hectare by FYM (1.5% N in general), then
1.5 kg N is supplied by 100 kg FYM
Then 120 kg N will be supplied by adding 100×120/1.5= 8000 kg or 8t/ha.
FOR INORGANIC
• The manure rate will depend on your initial soil fertility status and production goal (yield). There is no standard recommendation rates. It should be based on the soil test report.
(4bii)
(i) It provides cheap feedstuffs and organic manure for the fish ponds.
(ii) It Leads to proper management of the farm and better utilization of resources.

(5ai)
aquatic weed is a plant that grows (usually too densely) in an area such that it hinders the usefulness or enjoyment of that area.
(5aii)
{CHOOSE ANY TWO}
(i) Physical removal of weeds: It involves cutting, pulling, or raking weeds by hand. It is time-consuming and labor-intensive and is most suitable for small areas or for locations that cannot be reached by machinery.
(ii) Mechanical removal: It is accomplished by specialized harvesting machinery equipped with toothed blades and cutting bars to cut the vegetation, collect it, and haul it away. It is suitable for off-shore weed removal or to supplement chemical control.
(iii) Biological control: These methods generally involve the introduction of weed-eating fish, insects, competing plant species or weed pathogens into an area of high weed growth. While there are individual success stories (for example, stocking lakes with grass carp).
(5aiii)
CONCRETE POND
(i) Concrete ponds are Constructed on Land.
(ii) Concrete Ponds Are not Easy To Set up
FIBER TANK
(i) Fibertank can only be Constructed
Using a fiberglass tank to raise fishes
(ii) They are easy to set up
(5bi)
(i) All catfish, except members of Electric Catfish family, possess a strong, hollow, bony leading ray on their dorsal and pectoral fins
(ii) Catfish have a sweet, mild flesh which makes them important as food fish throughout the world
(iii) Catfish have no scales
(5bii)
(i) Salting the fish removes water and lowers the water activity
(ii) Salting of fishes prevent foul smell
(iii) Salting of fishes makes the fishes preserve for longer time
(5biii)
(i) DECAPITATION involves direct loss of brain function due to ischemia.
(ii)DEGUITING: A mixture of delight and guilt felt when a colleague, whom you despise, suffers a misfortune.
