    Observations on the monsoon prawn fishery in Kerala

    The ban on trawling in Kerala from June 15th to July 30th coincides with the southwest monsoon. During the period fishermen venture into the sea with their traditional/motorised crafts and gears such as thermocol boats (Alapuzha) and Thanguvallom (Ernakulam and Thrissur). The latter is operated with outboard engines and operate up to 8 km from the shore. The thermocol boats fish very near the shore (up to 3 km). The gear operated are ring seines or thangu vala and gill nets. The unique phenomenon in the monsoon season known as mud-bank or ‘chakara’ is characterised by calm areas close to the shore

    Tentoriceps cristatus (Klunzinger, 1884) commonly called as crested hair tail is a monotypic genus of cutlassfish family Trichiuridae. During the experimental fishery survey conducted by FV Silver pompano on 28 September 2016, specimens were obtained in the trawl net operated off Alappuzha (09º 21'N, 75º 56'E and 09º 21'N, 76º 18' E) at a depth of 50- 60m along with other fishes and crustaceans

    Feeding spectra and activity of the freshwater crab Trichodactylus kensleyi (Decapoda: Brachyura: Trichodactylidae) at La Plata basin

    Background: In inland water systems, it is important to characterize the trophic links in order to identify the ‘trophic species’ and, from the studies of functional diversity, understand the dynamics of matter and energy in these environments. The aim of this study is to analyze the natural diet of Trichodactylus kensleyi of subtropical rainforest streams and corroborate the temporal variation in the trophic activity during day hours. Results: A total of 15 major taxonomic groups were recognized in gut contents. The index of relative importance identified the following main prey items in decreasing order of importance: vegetal remains, oligochaetes, chironomid larvae, and algae. A significant difference was found in the amount of full stomachs during day hours showing a less trophic activity at midday and afternoon. The index of relative importance values evidenced the consumption of different prey according to day moments. Results of the gut content indicate that T. kensleyi is an omnivorous crab like other trichodactylid species. Opportunistic behavior is revealed by the ingestion of organisms abundant in streams such as oligochaetes and chironomid larvae. The consumption of allochthonous plant debris shows the importance of this crab as shredder in subtropical streams. However, the effective assimilation of plant matter is yet unknown in trichodactylid crabs. Conclusions: This research provides knowledge that complements previous studies about trophic relationships of trichodactylid crabs and supported the importance of T. kensleyi in the transference of energy and matter from benthic community and riparian sources to superior trophic levels using both macro- and microfauna.Fil: Williner, Verónica.

    A training on Tropical Finfish Stock Assessment was conducted by the Finfish Fisheries Division (FFD), ICARCMFRI, for Fisheries Resource Management scientists at ICAR-CMFRI Headquarters, Kochi during 16-27 August 2022, in hybrid mode. The program was inaugurated by Dr. A. Gopalakrishnan, Director, ICAR-CMFRI on 16th August 2022, and was attended by Dr. Sanjay Pandey, Asst. Commissioner (Fisheries), Govt. of India, Heads of Divisions at ICAR-CMFRI Headquarters and scientists of Finfish and Shellfish Fisheries Divisions of ICAR-CMFRI. In the second phase, a training - workshop on 'Stock assessment of shellfish species' was organised from 9 -17 November 2022 by the Shellfish Fisheries Division (SFD), with focus on specific methods for shellfish species. Scientists from the Fishery Resources Assessment, Economics and Extension Division (FRAEED), FFD and SFD were participants and resource persons in the respective programme

    Twenty four species of Pandalid shrimps reported from the Indian waters, of which six genera (Chlorotocella, Chlorotocus, Chlorocurtis, Dorodotes, Heterocarpoides and Stylopandalus) are represented by single species each. The genera, Plesionika and Heterocarpus are represented by eleven and seven species respectively. Plesionika adensameri (Balss, 1914) a deep-sea shrimp hitherto unreported from Indian waters is recorded from west coast of India. Information on some biological aspects of few Pandalid shrimps from Indian waters is also reported in the present paper

    Kerala with a coastline of 590 km is a significant contributor to the total marine fish landings of the country. A picture of the marine fisheries sector in Kerala during the years 2005 and 2010 is presented below (Table 1). With a continental shelf of about 40,000 km2 marine fisheries plays a vital role in the livelihood of the people
