RECOMMENDATIONS FOR HASTENING DEVELOPMENT OF GELATINOUS MUD AT NGOMENI PILOT FISH FARM
A. Slightly acid to slightly alkaline pond soils (pH 6.5–7.5)
B. Acidic soils (pH 5.0 to 6.0)
C. Acidic soils (pH 4 to 4.5)
2 Consultants' additional recommendations to Mr. Padlan's procedures.
CULTURE OF LABLAB AFTER FORMATION OF 5–10 CM LAYER OF HYDROPHILIC MUD
A. January to March (before long rains)
B. August to September
Note: In all operations A and B, pond may be stocked as soon as water has reached a depth of 25 to 30 cm. Ensure proper acclimatization measures, however, before releasing fish into the pond. Shrimps may be stocked if salinity is within growing range.
To do a correct sampling a castnet is used in many countries, but it cannot be used in Ngomeni due to the presence of branches in the pond to discourage poachers. A square trap net (60 × 60 cm) mounted on a frame can be used. It is left lying on the bottom of the pond with some bait for one hour; it is then suddenly pulled out of the water with all the shrimps that have been attracted. Such trap catch will give a more accurate evolution of the growth. The results of the sample as well as of the other parameters must be typed immediately and distributed to the staff. They can then be discussed and the programme adjusted during the following staff meeting.
The form is to be filled everyday; it must give a detailed report of what is happening in each pond.
Environmental data
Weather: it can be reported as sunny, cloudy or rainy.
Water exchange
The water exchange will be done automatically as soon as an improved gate design will be put in service. The water exchange will be noted as + on the day of exchange and O when there will be no exchange. The level must be recorded just after closing the gate and just before opening it. The salinity must be read with the refractometer every other day and just before opening the gate.
Lablab
The pond manager will appreciate the growth of lablab as none, little, normal or excess.
Comments
In this column will be specified the activity developed every day in each pond such as drying, elimination of crabs, fertilization with the type of fertilizer and the amount used in kg, preparation of lablab, stocking with the exact number, sampling, harvesting, etc.
Any additional intervention or unusual observations must be specified such as an anormal colour of the soil or the water, problems at the gate or maintenance of the pond (tilling, reinforcement of the dike, etc.).
