Right choice and proper operation of farm equipment contribute to the success in operating a fish capture. Fishermen should familiarize themselves with the uses of different fishery tools and equipment including safety measures to be observed in operating a farm. Keeping new equipment working at its top condition would make you work in the farm more effective and efficient. The easiest way to ensure your equipment is working at top performance is to completely understand its operations and maintenance.

Gasoline-powered Water Pump

[illustration: gasoline-powered water pump in a metal frame]

[illustration: labeled diagram of a gasoline-powered water pump showing its parts. Labels: FUEL TANK, THROTTLE LEVER, ENGINE SWITCH, MUFFLER, STARTER CORD, FUEL VALVE, SPARK PLUG CAP, AIR CLEANER, OIL FILLER]

Parts of Water Pump

A. Before Starting

Engine Oil

The pump has a low oil sensor and will not start or, if running, will cut out when the oil level drops too low.

1. Check the engine oil level on a flat, level surface before each use of the pump.
2. Fill to upper level mark with oil classified as SE or SF (SD if SE/SF not available).
3. Use SAE 10W-30 for general temperature operation.
4. Other viscosities may be used when the average temperature falls within the indicated range.

Engine Fuel

Avoid repeated or prolonged contact with skin or breathing of vapor

Do not overfill the fuel tank; make sure to leave an air gap between the fuel and top of the tank to account for fuel expansion. Use unleaded fuel only (octane rating of 86 or higher) and never use contaminated gasoline or an oil/gasoline mixture!

1. If the engine has been running, allow it to cool before adding fuel. Refill the tank outdoors.
2. Remove the gas cap slowly to relieve any pressure inside the tank.
3. Keep sparks flames, heat and other ignition sources away while adding or storing fuel.
4. Do not light a cigarette or smoke when refueling.
5. Wipe up any fuel spills.

Suction Hose

Must be of a type rated for suction so that it will not collapse when lifting water.

Hose Connections

1. Insert adapters (included in the package) into one end each of the suction and discharge hoses (not included in the package) and attach O-rings to the adapters.

   
   

2. Tighten the hose clamp around the discharge hose until the connection is airtight.

   
   

3. Insert a strainer into the suction hose (not included in the package) and tighten the hose clamp around the suction hose until the connection is airtight. Priming will be faster if you install a check valve (foot valve) near the strainer. An air leak may prevent priming and will reduce the output. Make sure the strainer won’t quickly become blocked with foreign material, such as small stones or sediment.

   
   

4. Screw the adapters into the appropriate pump fittings. Avoid sharp bends in the hoses, and don’t allow heavy objects to compress the hoses.

   
   

B. Priming

Remove the upper priming tank plug and fill the tank with water, replacing the plug afterward. Pumps are only self-priming when priming tanks have water and the suction head (lift to the pump) is 20 feet (6 meters) or less. The maximum pressure head (lift above the pump) is 80 feet (24 meters) for the GTP50Y or 90 feet (27 meters) for the GTP80Y.

Operation Guidelines

1. Ensure that the engine has the appropriate liquid to be pumped which comply to all applicable codes and regulations.

   
   

2. When the pump is used for the first time, break in the engine by operating it with the throttle half open (light load) for the first 24 hours before it goes into full speed operation. This will prolong the service life of the engine.

   
   

3. Install a check valve in suction lines to prevent liquid fall back when the pump is shut off. It may be necessary to vent the top of the pump in order to blow out air during repriming.

   
   

C Starting the Engine

1. Place the pump on a level surface.
2. Switch the engine’s fuel valve lever to the “on” position.

[illustration: close-up of the engine with the FUEL VALVE LEVER labeled]

3. Turn the choke lever to the position shown.

[illustration: close-up of the engine with the CHOKE LEVER labeled]

4. Turn the throttle lever slightly to the right.

[illustration: close-up of the engine with the THROTTLE LEVER labeled]

5.Switch “on” the engine.

[illustration: engine switch panel labeled SWITCH ENGINE]

6. Pull slowly the starter cord until it engages. Then pull hard.

[illustration: engine with the STARTER CORD labeled and an arrow showing the pull direction]

Caution. Do not allow the starter cord to snap back. Return it slowly by hand.

7. As the engine warms up, return the choke lever to its original position and set the throttle lever in the desired position—move it right to increase engine speed and left to decrease engine speed.

[illustration: close-up of the engine with the CHOKE LEVER labeled]

Pump Operation Guidelines

1. Clean the machine and check the condition of its parts.

   
   

2. Make sure the connections are tight and no fuel is leaking after each use.

   
   

3. Save fuel and engine life by reducing engine speed for shallow lifts or small water volumes.

   
   

ATTENTION: Never Operate the pump without water for an extended length of time

1. After pumping corrosive water, such as seawater, hot spring water or water containing chemicals/pesticides, operate the pump with fresh clean water for three minutes to avoid pump corrosion.
2. In cold weather, completely drain (using the lower priming tank plug) any remaining water inside the pump after each use to prevent damage from water freezing.

D. High Altitude Operation

The standard carburetor air-fuel mixture will be too rich at high altitude (5,000 feet or 1,500-m and above), decreasing performance and increasing fuel consumption.

E. Stopping the Engine

Switch off the engine and turn the fuel lever to “off” position.

F. Transport

1. Make sure the engine switch and fuel lever are in the “off”.
2. Keep the unit level to prevent fuel spillage. Fuel vapor or spillage may ignite.

WARNING: Contact with a hot engine or exhaust system can cause serious burns or fired. Let the engine cool before transporting the unit.

1. Take care not to drop or strike the pump while transporting.
2. Do not place heavy objects on the pump.
3. Never operate a damaged or defective motor! When adjusting or making repairs to your pump disconnect the spark plug wire from the spark plug and place it away from the spark plug.
4. Do not use a garden hose to clean the pump because water can enter the fuel system and cause problems.

Generators

[photo: grey generator unit with a white control panel and gauge; small printed text “Onyx” on the base]

Our AirSep Oxygen Generators are a proven alternative to any other source of oxygen supply and are the most cost effective and safest oxygen source available for use in aquaculture/fish farming.

Sprayers

[photo: self-propelled sprayer with a boom spraying a plowed field]

While sprayers were once a niche product, today sprayers have become an essential piece of farm equipment for effective crop production. By properly applying chemicals to control weeds, insects, and diseases, you give your crop the best chance for high yields.

The uptick in self-propelled sprayer ownership started in 2005 when there was an increase in Asian soybean rust and farmers needed to have a sprayer available to make timely fungicide applications. Guidance systems and advanced controls have also made sprayers much easier to operate, contributing to the acceleration of on-farm sprayers.

Pre- operation check-up

1. Check your tires – Not only should you check the air pressure but also make sure that the lug nuts are tight and look at the condition (e.g., tread) of the tires. If you notice that you have low tire pressure, look for air leakage from around the valve stem
2. Brake Fluid – Look for any fluid leaks on the ground beneath the tractor. Also check fluid levels for coolant, engine oil, and hydraulic oil levels as well.
3. Fuel – You always want to make sure you have sufficient fuel in the tank.
4. Battery – Make sure that the battery terminals are not corroded.
5. Oil or hydraulic leaks on the ground beneath the tractor
6. Water – prevent the walls from cracking when exposed under the sun.

V. OTHER AQUACULTURE FACILTIES

A. Fishpond

A. Fishpond is a pond walls or dikes which hold in water; pipes or channels, which carry water into or away from the ponds. It is different from a river or a stream because it does not have moving water and it differs from a lake because it has a small area and is no more than around 1.8m deep.

[illustration: drawing of terraced fields or fish ponds separated by dikes, with trees and a small structure at the lower right]

B. Fish Tank a tank or pool or bowl filled with water for keeping live fish and underwater animals. The size of the tank varies from 0.5 – 0.1hectare with a water depth of about 1.5- 2.0m. The recommended characteristics for fish raising in tanks are as follows; the interior surface in tanks should be smooth to prevent abrasion. The surfaces should be nontoxic.

[illustration: drawing of a round fish tank connected by pipes to a filter unit and other equipment]

C. Fish Pen and Cages

Fish cage and fish holding pens farming is attractive to many individuals because a large crop can be raised tended and harvested in a small area. Since the fish are in concentrated area, problems can be quickly recognized and address.

Fish cage farming are made from either a hard plastic mesh or wire webbing. Flexible cages are made by building a frame, then covering it with netting made from nylon or a similar material.

[illustration: drawing of a square net enclosure with posts and floats set in water]

What is It

Cage’ refers to the type of culturing units consisting of a framed net open at the top and floating on the surface, or when completely enclosed, the cage is kept below the water surface by adjustable buoyancy or suspending from the surface. Pen’ refers to that type of culturing unit where one part of the natural water body is enclosed by a fence-like wall resting on the bottom.

The increasing popularity of cage culture world-wide can be attributed to the following advantages: The applicability of cage culture is extremely varied. Rivers, backwaters, reservoirs, lakes, strip-mine lakes, irrigation canals etc., are all suitable for culture without any alteration in their state or function. The production in small units (cages) as well as their quick and simple harvest render the method capable both for flexible adaptation to the actual market demands and for continuous supply.

Cages are a convenient means of wintering, thus they save the vast investments for separate wintering ponds. Due to the high stocking density of enclosures, the direct observation of fish and immediate intervention, if necessary, are possible. By producing seed for stocking natural waters in cages, building nursery ponds can be avoided. An indirect advantage is that by utilizing existing natural waters, land areas for fish ponds can be used for other rural activities. Cage culture can be well associated with sport fishing.
