Role of Krishi Vigyan Kendra (KVK) In Fisheries Extension
The Krishi Vigyan Kendras (KVK) in the country was established in 1974 with the first one at Pondicherry subsequent to the detailed discussions and studies followed by the recommendation of the Education Commission (1964-66), Govt. of India. The initial objective was to establish specialized institutions to provide vocational education in agriculture and allied fields at the pre and post matriculate levels to cater the training needs of a large number of boys and girls coming from rural areas. Thus Krishi Vigyan Kendras (Agricultural Science Centres) were established as innovative institutions for imparting vocational training to the practicing farmers, school dropouts and field level extension functionaries

Evaluation of Anabas testudineus Farming in Natural Ponds and Impact on Subsequent Crop
The climbing perch ( ) is a species of amphibious freshwater fish in the family Anabantidae and is widely found across the globe. This fish can survive without water for a short period by resting under the mud during dry seasons. They do aerial respiration
using paired suprabranchial labyrinthiform organs. This fish was used as a biocontrol agent against mosquitoes in confined water bodies,
including rice fields, as they can feed on insects at the water surface. The performance of monoculture Anabas in natural ponds and impacts on
the consecutive carp culture in the same pond are evaluated in the present study. The average production of Anabas recorded was 1.39 Kg per
m area of the pond with survival of 57.33%. The significant reduction survival percentage of carps was observed in the second crop. The 2
reduction in carp stock was observed due to the predation by retained Anabas of the previous culture. They resist the toxicity of sea seed cake
once hidden in the pond bottom. They might have survived inside the deep layer of clay with the help of respiratory support of the labyrinth and
were established later. The study confirms the opportunistic carnivore feeding behavior without other feeds. The study concludes that Anabas
is a good candidate fish for places where water availability is an issue. Proper fencing around the ponds needed to check its movement out and
through the land. When a different candidate species is planned for the subsequent crop, complete harvest, even from the deeper portions of
the pond bottom, must be ensured to prevent surviving Anabas from feeding on the fingerlings of the next crop
Pokkali: An Exquisite Climate Resilient and Organic Rice-Prawn Production System for Future
The globe is facing
faster climatic changes
in the 21st century
than in the past.
The world’s average
temperature is rising
and is accompanied by flooding,
drought, and erratic rainfalls. The
change in soil and water salinity is
a peripheral impact of this utmost
weather conditions. These climatic
changes have a significant effect
on agricultural production, making climate -adaptive crops
extremely valuable at this time.
Pokkali is the oldest indigenous
rice variety that has 3000
years of organic cultivation
and climate resilience history.
The journey of Pokkali rice
began from a flood, where
earlier Pokkali was wild rice that
was seen in the western ghats
of India and was carried by
the flood to low-lying coastal
saline areas. All the climatic
stress was overcome in this
great journey and it developed
resistance to flood and salinity.
It is grown in the water-logged,
coastal regions of Ernakulam,
Thrissur, and Alappuzha
districts in Kerala and is well
known for its flood, saline
tolerance, and high nutritional
value. The rice got its name
Pokkali, because of its notable
height, which can grow up to
6 feet. In Malayalam, Pokkali
is a term used to describe
someone who dominates in
height over others. Pokkali
rice cultivation alternated with
extensive aquaculture is known
as Pokkali farming
Accelerated seed production of pearl spot using modified hatchery method
Pearl spot (Etroplus suratensis), popularly known in Malayalam
as karimeen is an indigenous fish extensively found along
the east and south-west coasts of Peninsular India (Jhingran
and Natarajan, 1969,1973). Pearl spot is popular in Kerala for
its taste and appearance. It is an elegant and exotic dish during
the festivals of all occasions in Kerala. It is also inevitable in the
non-vegetarian dishes of both foreign and native tourists in the
house boats and resorts located along the coastal line of Kerala
