Results of the Austrian-Ceylonese hydrobiological mission 1970 of the 1st Zoological Institute of the University of Vienna (Austria) and the Department of Zoology of the Vidyalankara University of Ceylon, Kelaniya. Pt. 4. List of reptilia and amphibia collected in the mountains of south-west Ceylon, with notes on finding localities

Sri Lanka is a comparatively small island (65.584 km²) within the equatorial belt of calms. There are only slight seasonal variations in temperature, air humidity and day length. A description is given of the amphibian and reptile material brought back from the Austrian Indo-Pacific expedition, 1970-71. Some notes on the habitat of the animals are included.

Voluntary guidelines for securing sustainable small-scale fisheries in the context of food security and poverty eradication: summary

The Voluntary Guidelines for Securing Sustainable Small-scale Fisheries in the Context of Food Security and Poverty Eradication (SSF Guidelines) were adopted by member countries of the Food and Agriculture Organization of the United Nations (FAO) and were officially approved as an international instrument in June 2014. What is very special about the SSF Guidelines is that it was created as a result of a very long history of the struggles of small-scale fishworkers around the world appealing for greater recognition of their status and their role in the fisheries sector of their countries. These Guidelines have 100 paragraphs which are distributed across 13 sections. This document is only a summation of the contents of the Guidelines. It was produced for ICSF by John Kurien, founder Member of ICSF, who has worked for the last four decades with small-scale fishing communities in many areas around the world, particularly in Kerala, India.

Eyes on their fingertips: some aspects of the arts, science, technology and culture of the fisherfolk of Trivandrum, India

Eyes on Their Finger Tips deals with the traditional marine wisdom of a set of people and the rarest of rare experiences they have had at sea. Through these numerous chapters he takes us into the seas of the fishers. It is a voyage which we cannot make in reality. But through the heroic deeds of his father, the riddles of oldman Sebesti, the shark story of brother Kamalappan, and the rituals of his mother, we get a fascinating peep into the wisdom of the watery world of the small-scale fishers of Trivandrum, Kerala, India.

Smoke curing of mussels

Substantial quantities of green mussels are available on the Kerala coast particularly from Calicut to north. But these are not properly exploited at present. Simple and economic methods of processing like drying and smoking can go a long way towards market promotion and better returns to the fishermen. This paper reports the method of preparation of smoked mussels which have a great potential for export as well as local marketing.

A review on oil sardine 3. Oil and meal industry

The author reviews the advances in the oil and meal industries related to the oil sardine fishery (Sardinella longiceps) since the 1920s. Data on the production of by-produced produced in Kerala over the period 1964- 69 are tabulated. Details of the properties of the commercial oil are given, and the values compared to those for other similar oils. The use of oil sardine for industrial purposes - the oil has been used to cure leather, temper metals and as fungicides or insecticides - and the production of fish meal and fish protein concentrate is considered.

Canning of Lactarius

Though not a sizable fishery on national level, landings of lactarius (Lactarius lactarius) is considerable in the states of Kerala and Tamil Nadu. Apart from a note (Anon, 1965) no published work is available on its preservation by canning. Fish processed by this method on storage loses its flavour and the lustrous skin is peeled off. The present note describes a method in which these factors also are taken care of.

Ecology of Indian estuaries-XI. A preliminary survey of the fishery resources of the Ashtamudi estuarine system

The fish fauna of the Ashtamudi, the second largest estuarine system in Kerala (8°53'-9°02' N Lat. and 76°31'-76°41' E Long.) is listed. 97 species belonging to 39 families have been recorded, ofwhich69 are commercially important contributing to the fisheries of the Ashtamudi Estuary. Mullets, cichlids and the glassy perchlets are the most abundant groups and contribute appreciably to the landings. Results revealed that the estuarine system supports a good capture fishery which is seasonal. Majority of the fish fauna in the estuary are marine elements recruited from the adjoining Arabian Sea. An inventory of the craft and gear employed is presented and the sources of pollution in the estuarine system are described, aquacultural prospects of this area are discussed.

Mercury toxicity in two intertidal tropical marine molluscs

Lethal and sub-lethal effects of mercury have been studied in Perna viridis and Modiolus carvalhoi. For P. viridis LC30 is 1.0 p.p.m. at 48 h and 0.23 p.p.m. at 96 h. Recorded LC50 values for M. carvalhoi are 0.5 p.p.m. and 0.19 p.p.m. at 48 h and 96 h respectively. The results document that these two species, although inhabiting the same area in the tidal belt, exhibit clear differences in mercury resistance. It is further shown that the duration of exposure affects mortality rates. In sub-lethal concentration, between 0.01 and 0.10 p.p.m. decrease in pedal-gland activity is conspicuous in P. viridis. At concentrations much below LC50 values (at 96 h), although some animals are alive, pedal-gland activity is totally suspended, supporting the assumption that shell closure ability plays a minor role in byssus thread production. In M. carvalhoi total cessation of pedal gland activity occurred at 0.09 p.p.m. of mercury.
