Landings of Penaeus vannamei at Kalamukku Fish landing Centre, Kerala

Penaeus vannamei Boone, 1931 commonly known as the white legged shrimp was observed along with Penaeus indicus in the landings at Kalamukku fish landing centre Ernakulam,on 15.11.20 18. The catch was from a single day trawler whose depth of operation was 15 m. Distributed along the Pacific coast of Mexico, central and south America up to Peru, the shrimp was introduced in India on a pilot scale for culture in 2003 and later in 2009 large scale production began. However, it was not recorded in the wild capture fisheries for shrimps. In the landings at Kalamukku, the females measured 109 to 146 mm in total length and weighed 8.9 to 26.6 g. The males measured 100 to 145 mm in total length and 7.5 to 24.4 g in weight. Among the sample analysed 51% were P. vannamei and 49% were P. indicus based on numbers. Its appearance in the landings is most likely due to the recent floods in Kerala during August, 2018

A brief note on portunid crab, Charybdis (Goniohellenus) omanensis septentrionalis from southwest coast of India

Crustacean Fisheries Division of ICAR-CMFRI, has recently taken up a two year programme on experimental trawling using fishing vessel F.V. Silver Pompano. Samples were collected from different bathymetric stations off Kochi and Alappuzha during fortnightly intervals. Samples in the last fortnight of August 2016, collected at a depth of 65m off Alappuzha, included a good number of Charybdis (Goniohellenus) smithii along with fishes and other crustaceans. While segregating the samples of swarming crab C. (G.) smithii, approximately 5 kg of small sized Charybdis sp. was also collected. This species was not included in the earlier samplings of the programme as well as in the commercial fishery landings. Hence detailed studies were carried out and found the species is C.(G.) omanensis septentrionalis, a new record in the Indian seas

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

Note on the shoal of Priacanthus hamrur caught during experimental trawling

During the experimental fishing conducted by F V Silver pompano on 10th November 2016, a shoal of bullseye Priacanthus hamrur, weighing 1.5 t, was caught at 65-70 m depth off Alappuzha coast (90 25' 51'’ N, 750 58' 49'’ E). The shrimp trawl net with cod end mesh size of 20 mm was operated for an hour and the total catch comprised of P. hamrur (99%) and Uroteuthis (Photololigo) duvaucelii (1%)

Brief note on the ribbonfish Tentoriceps cristatus from the southwest coast of India

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

Saga of inshore prawn fishery of Kerala

The marine shrimp fishery in Kerala existed even before the advent of the Indo-Norwegian project. (INP), but the genesis of a commercial-scale fishery happened due to the INP. Earlier fished by artisanal crafts and gears, the introduction of trawlers saw the establishment of shrimps as the major marine fishery commodity. The penaeid shrimps Metapenaeus dobsoni, Parapenaeopsis stylifera, Penaeus indicus, Metapenaeus monoceros and Metapenaeus affinis are prominent in the inshore shrimp fishery of the state. Many developmental changes which happened from time to time in craft and gear technology and the extension of fishing grounds brought considerable changes in the fishing pattern have influenced the inshore shrimp fishery of Kerala which can be classified into five phases – primary, growth, declining, enhanced growth and stagnant

Effect of angiotensin-converting enzyme inhibitor and angiotensin receptor blocker initiation on organ support-free days in patients hospitalized with COVID-19

IMPORTANCE Overactivation of the renin-angiotensin system (RAS) may contribute to poor clinical outcomes in patients with COVID-19. Objective To determine whether angiotensin-converting enzyme (ACE) inhibitor or angiotensin receptor blocker (ARB) initiation improves outcomes in patients hospitalized for COVID-19. DESIGN, SETTING, AND PARTICIPANTS In an ongoing, adaptive platform randomized clinical trial, 721 critically ill and 58 non–critically ill hospitalized adults were randomized to receive an RAS inhibitor or control between March 16, 2021, and February 25, 2022, at 69 sites in 7 countries (final follow-up on June 1, 2022). INTERVENTIONS Patients were randomized to receive open-label initiation of an ACE inhibitor (n = 257), ARB (n = 248), ARB in combination with DMX-200 (a chemokine receptor-2 inhibitor; n = 10), or no RAS inhibitor (control; n = 264) for up to 10 days. MAIN OUTCOMES AND MEASURES The primary outcome was organ support–free days, a composite of hospital survival and days alive without cardiovascular or respiratory organ support through 21 days. The primary analysis was a bayesian cumulative logistic model. Odds ratios (ORs) greater than 1 represent improved outcomes. RESULTS On February 25, 2022, enrollment was discontinued due to safety concerns. Among 679 critically ill patients with available primary outcome data, the median age was 56 years and 239 participants (35.2%) were women. Median (IQR) organ support–free days among critically ill patients was 10 (–1 to 16) in the ACE inhibitor group (n = 231), 8 (–1 to 17) in the ARB group (n = 217), and 12 (0 to 17) in the control group (n = 231) (median adjusted odds ratios of 0.77 [95% bayesian credible interval, 0.58-1.06] for improvement for ACE inhibitor and 0.76 [95% credible interval, 0.56-1.05] for ARB compared with control). The posterior probabilities that ACE inhibitors and ARBs worsened organ support–free days compared with control were 94.9% and 95.4%, respectively. Hospital survival occurred in 166 of 231 critically ill participants (71.9%) in the ACE inhibitor group, 152 of 217 (70.0%) in the ARB group, and 182 of 231 (78.8%) in the control group (posterior probabilities that ACE inhibitor and ARB worsened hospital survival compared with control were 95.3% and 98.1%, respectively). CONCLUSIONS AND RELEVANCE In this trial, among critically ill adults with COVID-19, initiation of an ACE inhibitor or ARB did not improve, and likely worsened, clinical outcomes.
