Being a Low Impact Fuel Efficient (LIFE) fishing method, fish aggregating device is a (FAD) is a renowned technology in the climate change era to reduce carbon emission from the mechanized fishing sector. In India fishing system for the fishery of high value cuttlefishes and squids is practiced in the southern maritime state of Kerala. Fishers of Vizhinjam fishing village in Kerala use a traditional FAD called "Akkadi" made of coconut peduncle for harvesting cephalopods from the rocky continental areas of Wadge bank, where modern fishing technologies did not yield good results. A participatory survey was conducted in Vizhinjam fishing village during December 2018 to February 2019 for evaluating the design, operational performance and economics of "Akkadi". The fishers use 7 to 10 m long plank built/ FRP boat known as "Vallam" for the fishery. The "Akkadi" made of rope tied to 4 to 6 m long manacles of coconut peduncle, moored with the help of sand filled plastic gunny bags and buoyancy is maintained with the help of empty plastic kerosene cans. Similarly small FAD covered area made by inter-connecting 10 to 20 manacles while maintaining one meter distance between the two adjacent manacles. The fishers use 3 to 5 mm thick polypropylene (PP) ropes for making each manacle and 1 to 2 cm PP ropes to rig float and sinker. After installation, fishers mark the location with help of phone GPS. The biodegradable manacles start to degrade within two days, which establish a good diversity of periphyton and plankton thereby increasing the productivity of the region.  Cephalopods are attracted towards "Akkadi" for shelter, breeding and food. One week later fishers start to use hand jigs near the "Akkadi" at night hours with lights and harvest good qualities of large squids and cuttlefishes and this FAD has a maximum life of six months and fishers earn an average net profit of about 35000 Indian rupees per month from a single FAD system. The traditional FAD of the village is a good example of resource management through species specificity along with environmental friendly green fishing technology that could be tried in other parts of the country using locally available material for enhancing fish production while maintaining sustainability.
