Vulnerability of Coastal Fisher Households to Climate Change: A Case Study from Gujarat, India

Vulnerability of Coastal Fisher Households to Climate Change: A Case Study from Gujarat, India - CMFRI Repository

The impacts of climate change are invariably seen on agriculture, aquatic ecosystem, energy, and economics. The fishery sector on which livelihood of world’s 36 million fishers depends is also not untouched but a little attention has been given to study the vulnerability of fisherfolk population to climate change programs. Therefore, the present study was envisaged to assess the vulnerability of fishers to the climate change in Junagadh district of Gujarat, India. The vulnerability of 1500 fisher household was assessed using PARS (parameter, attribute, resilient indicator, score) methodology, in four coastal villages namely Old light house, Bhidiya, Navabunder and Rajpara in Junagadh district. Five parameters viz., fishery, economy, social, environmental and development drivers have been assessed as indicators of sensitivity, exposure and adaptive capacity. ‘Economy’ was found to be the most impacted parameter consequent to climate change followed by the ‘social’ and ‘environmental’ parameters. The results obtained reflect low adaptive capacity of fishers that could be attributed to lack of awareness, preparation, and mitigation option. Thus, the finding of the study could be used as a vital input while developing the policy and suitable action plan to combat the impacts of climate change minimizing the risk to fisheries sector.

Grouper Culture - A New Venture for Indian Aqua Farmers

Grouper Culture - A New Venture for Indian Aqua Farmers - CMFRI Repository

Groupers are carnivorous reef fishes; belonging to the subfamily Epinephelinae with 15 genera and 159 species. They are available globally but are predominant in the tropical and sub-tropical waters including the Indo- Pacific region (110 species), the East Atlantic and Mediterranean regions (14 species) and the inter-tropical American zone (35 species) (Pierre et al., 2007). They mainly inhabit coral reefs, rocky areas, sea grass bed and estuaries. Groupers are popular carnivorous fishes with a high market demand in many parts of the world and form the mainstay in the world Live Reef Food Fish (LRFF) trade (Koesshendrajan & Hartono, 2006). In coral reef ecosystems, a diversity of species is harvested worldwide and the major groups of fishes traded include snappers, surgeon fishes, unicorn fishes, parrot fishes, emperor breams and groupers.

An Assessment on Economic Impact of Growth Over Fishing of Commercially Important Marine Ariids Along Mumbai, Northwest Coast of India

An Assessment on Economic Impact of Growth Over Fishing of Commercially Important Marine Ariids Along Mumbai, Northwest Coast of India. - CMFRI Repository

The economic assessment on juvenile landings of four dominant marine catfishes at New Ferry Wharf (NFW) landing centre, Mumbai, Northwest coast of India was carried out during January to December, 2013. The dominant catfishes viz. Nemapteryx caelata (19.7 %), Plicofollis dussumieri (21.5 %), P. tenuispinis (24.8 %) and Osteogeneiosus militaris (27.5 %) together contributing 93% of total marine catfish landings of the state. Among four species, the juvenile landings of N. caelata contribute maximum (93.17 %) followed by P. dussumieri (57.14 %), O. militaris (36.11 %) and P. tenuispinis (21.43 %) with the maximum landing during November to March . The bioeconomic model reveals that if juveniles are allowed to grow up to length at first maturity (Lm); an estimated total annual economic gain will be Rs. 13.15 crores with an estimated biomass gain of 1222 t per annum. The estimated total annual biomass is increased by 2.07 times with an increase in additional revenue by 3.7 times would have been realised. The results of present study suggest that sustainable harvest of these resources would have been yielded maximum economic return to the fishers. With the help of stakeholders participatory approach, management measures such as strict mesh size regulation, effort restriction on bottom trawl up to 50 m depth and awareness campign on catching juveniles and adult in particular to the oral incubated male ariids, would have been implemented during November to March to avoid growth overfishing.

First report of two new antioxidative meroterpeno 2H-pyranoids from short-necked yellow-foot clam Paphia malabarica (family: Veneridae) with bioactivity against pro-inflammatory cyclooxygenases and lipoxygenase - CMFRI Repository

Two new meroterpeno 2H-pyranoids were isolated from the EtOAc:MeOH extract of yellow-foot clam Paphia malabarica. The structures of these newly reported compounds were elucidated based on spectroscopic interpretations. This is the first report of biogenic 2H-pyrans bearing decadienyl and allyloxy-(isopentanyl)-cyclohexene skeletons from marine biota.

Vulnerability Assessment of Coastal Fisher Households in Tamil Nadu, India: A Climate Change Perspective

Vulnerability Assessment of Coastal Fisher Households in Tamil Nadu, India: A Climate Change Perspective - CMFRI Repository

The coastal district vulnerability index was derived for different coastal districts of Tamil Nadu based on the Patnaik and Narayan model. The selection of the district was based on assessment of coastal district vulnerability index estimated for different coastal districts (Table 1) of Tamil Nadu. Based on these parameters vulnerability index was analyzed and Ramanathapuram had the highest vulnerability followed by Kanyakumari and Nagapattinam.

Assessing the Socioeconomic profile of a vulnerable coastal fishing village in India

Assessing the Socioeconomic profile of a vulnerable coastal fishing village in India - CMFRI Repository

Fisheries sector attained immense importance around the globe with augmenting income and employment generation. Indian fisheries sector provide dependency for over 14.5 million people across the country with Gujarat, Tamil Nadu, and Kerala, being the top three marine fish producing states of the country. Even possessing the highest literacy rate in the country, the irony exists that the fishers of Kerala are marginalized far way behind with comparatively higher level of literacy rate and educational attainment which limits them with minimal alternative livelihood options.This study is an attempt to examine the socio-economic profile of the fishing community in the Poonthura fishing village of the Thiruvananthapuram district of Kerala, where fishing is the most important economic activity. Among the 222 fishing villages of Kerala, Thiruvananthapuram has the maximum number of marine fishing villages (19 per cent) where in fishermen reside. Poonthura village is one of the major fishing villages from the South West hotspot regions of India, situated in the suburbs of Thiruvananthapuram district, the capital of Kerala. The study analyzed various socioeconomic aspects such as thefishing activity, basic household data, economic as well as historic and cultural dependence on fishing, gender equity, employment and occupational structure, community infrastructure, income distribution and assets, physical capital, financial capital, social capital, and exposure of the fishermen families by taking 500 samples from the study area. Even though the village is having a century old fishery culture and a strong emotional attachment to the fishing job, people are not ready to direct their young generation into this sector which indicates the higher level of vulnerability prevailing in the sector. The study as the first of its kind conducted at one of the most vulnerable marine hotspot of Kerala and which explains the problems, prospects of the inhabitants in the sector has its own relevance as a basis to develop proper adaptation mitigation strategies for the fisher folks.
