Exploitation of juveniles of the spinycheek grouper, Epinephelus diacanthus by multiday trawlers along Dakshina Kannada coast

The juveniles in the size range 9-24 cm are in sizeable quantities during October - May at Mangalore and Malpe landing centres of Dakshina Kannada coast. The present study is undertaken to highlight the magnitude of the exploitation of the juveniles of the Spinycheek grouper. Epinephelus diacanthus by trawlers along the Dakshina Kannada coast and its impact on the stock with a brief description on its biology. This species is known to grow to a large size and supports a fishery of some magnitude in other parts of the Indian coast. The results presented here are based on the data collected on the landing of the species at Mangalore and Malpe during 1988/'89 - 1993-'9

Migrant labourers in the marine fisheries sector

It is now recognised that migration is an integral part of the survival strategies of the poor; especially where local economics offer limited livelihood alternatives. Intervention strategies should, therefore, be directed at reducing the vulnerability of migrants, not at reducing migration itself. Migration has become a key facet of today’s world. Migrants living outside their country of birth are 191 million

High abundance of large sized rock cods (Epinephelus spp.) off Karnataka coast during the postmonsoon month of September

some of the multi-day units ventured into deeper waters (60-80 m) and obtained good catches of reef cods (Fig: 1) along with threadfin breams and cuttle fishes. Encouraged by this, more number of multi-day units were put into operation in September of the following year (1995) and got still better catches of reef cods

Catfish reappeared in Dakshina Kannada Coast

After a gap of several years catfish reappeared in Malpe during September, 1994. Three purse seiners together landed three tonnes of catfish Tachysurus serratus (90 per cent) and T. dussumieri (10 per cent

Whitefish

The whitefish, Lactarius lactarius, which is the only species in the Family Lactariidae has distribution all along the Indian coast. Though small in size, attaining a maximum of 330 mm, it fetches good price due to its good taste and consumer preference. It is also called false trevally and bigjawed jumper and is called katali in Gujarat, saundala in Maharashtra, adameenu in Karnataka, parava or adavu in Kerala, kuthippu or suthumbu in Tamil Nadu and sating in West Bengal. In recent years, the whitefish has caught the special attention of fishery biologists and conservationists since its landings has greatly decreased

Boat building at Malpe in Udupi District of Karnataka - an alternate livelihood option

An attempt was made to survey the boat builders of Malpe Fisheries Harbour and to analyse how boat building forms an alternate source of income generation and livelihood. There are two boat building yards at Malpe, one near Malpe Fisheries Harbour and another at Angarkatte, 5 km from Malpe. The boat-building yard at Malpe is 35 years old and the technology of boat building is a traditional profession and is the monopoly of the Aachari community

Primary, Secondary and Tertiary Sectors in Marine Fisheries of Karnataka, India: A Socio-economic Profile

Marine Fisheries sector is a conglomeration of different categories of stake holders. The present study was conducted at Malpe fisheries harbour of Udupi district of Karnataka. The major categories of stakeholders were identified in the primary sector, the secondary sector and the tertiary sector. The socio-economic characteristics of each of these categories have a major bearing on the fisheries economy of the country. The study was conducted among a sample of 300 respondents, consisting of 74 from the primary sector, 133 from secondary sector and 93 respondents from the tertiary sector. The findings of the study revealed that among primary sector stakeholders, 86.66 percent of the Purse-seine operating laborers had undergone high school level of education. With respect to the average monthly income, the purse-seine operating owners had the highest average monthly income of Rs. 3.63 lakhs. This was followed by mechanized multi-day trawler operating owners with an average monthly income of Rs. 60,000. The purse-seiner single day labourer had an average monthly income of Rs. 9316 followed by the multi-day trawler labourer who had an average monthly income of Rs. 6700. Majority (60 percent) belonging to mechanized multi-day trawler operating owner category had availed loans during the current year. The major sources of loans were public banks. Among the secondary sector stakeholders, the wholesalers (58.06%) had high school level of education. 70.00 % of the women fish vendors had undergone lower primary level of education. With respect to the average monthly income, wholesalers had the highest average monthly income of Rs. 21,096. Decision making with respect to investments in business were done largely by men among the secondary sector stakeholders. Among the tertiary sector stakeholders, it could be observed that, majority of the petty shop owners of landing centres (80.64%) had undergone high school level of education. The average monthly income was maximum for the suppliers of auxiliary items

Innovations in the trawl fisheries of Karnataka and its possible impact on fisheries sector

Mechanisation of fishing operation in Karnataka was initiated with the introduction of 30 to 43 feet trawlers in 1957 for exploiting inshore demersal resources including shrimps. Introduction of purse seiners in the 1970s extended the area of fishing operation and enhanced pelagic fish landings significantly. Motorisation of traditional crafts like gillnetters and longliners and encouragement of offshore fishing beyond 50 m depth using bigger vessels for duration of 12-15 days have effectively increased the range and effort of fishing operations. Further, financial institutions have extended loan facilities for acquiring fishing boats which helped to enhance the fleet strength

Unusual landing of catfish by purse seine at Malpe, Dakshina Kannada

For the last several years, cat fish did not form a fishery at Malpe in Dakshina Kannada in Karnataka. On 30-09-94, three purse seines landed about 3 tonnes of catfish. All the three units operated at a depth of 36 metres off Malpe. The catfish catch was comprised of Tachysurus serratus (90%) and T. dussumieri[10%)

Fall Armyworm (Spodoptera frugiperda)

The fall armyworm (FAW), Spodoptera frugiperda (J. E. Smith) (Lepidoptera: Noctuidae), originated from America but is reported recently from Africa and the Asia-Pacific. FAW has caused huge international concern since its outbreak in Africa since 2016 and in Asia since mid-2018. The chapter mainly reviews its global distribution, life cycle, identification characters, strains, host plants, nature of damage, economic damage, and integrated pest management strategies available. The pest completes its life cycle on maize in 30 days (in warm summer months); in cooler temperatures, it may extend up to 60–90 days. For effective management of fall armyworm, different tools, viz., cultural control, agronomic management, breeding for resistance, natural enemies, and eco-friendly insecticides, should be used in an integrated approach. As the insect is recently introduced to Africa and the Asia-Pacific, possible management strategies and future cases of action are discussed
