Dr Trilochan Mohapatra releases ICAR-CMFRI’s nutraceutical product to combat hypertension
Dr Trilochan Mohapatra, Secretary, DARE and Director General, Indian Council of Agricultural Research (ICAR) in the presence of Dr J K Jena, Deputy Director General (Fisheries), ICAR released CadalminTM Antihypertensive extract (CadalminTM AHe), a nutraceutical product developed by ICAR-Central Marine Fisheries Research Institute (CMFRI), as a natural remedy for hypertension on 25th May 2019.
CadalminTM AHe was developed from seaweeds, which are commonly available in the Indian coastal waters. Seaweeds are the natural bounty of the Sea, and are known for their extraordinary medicinal properties. Bioactive pharmacophore leads from seaweeds were used to develop this nutraceutical product, which can be administered orally to regulate hypertension that is one of the risk factors for strokes, heart attacks, heart failure, and arterial aneurysm, and is a cause of chronic kidney failure. CadalminTM Antihypertensive extract contains 100% natural marine bioactive ingredients from selected seaweeds by a patented technology, and would be made available in 400 mg capsules. This nutraceutical does not have any side effects as established by detailed preclinical trials. CadalminTM AHe is the only product made by 100% natural marine bioactive ingredients from seaweeds as a natural remedy of hypertension.
This is sixth in the series of the nutraceutical products developed by ICAR-CMFRI. Earlier, the Institute had developed two anti-arthritic, one each of anti-diabetic, antidyslipidemic, and antihypothyroid nutraceuticals. These technologies have been commercialized through pharmaceutical companies.
Addressing the scientists and staff of ICAR-CMFRI, the Director General said that development of technologies and knowledge system should be in a way of disruptive in nature. Giant leaps could be made through disruptive changes in technologies and innovations which will also bring in wider visibility across the spectrum nationally and globally.
Dr Mohapatra urged the young scientists to come forward to make constructive changes in their respective field by building their own ideas. The future leadership must spring from the young scientists. Change is essential and the youngsters should focus on bringing in novelty to the existing technologies, he added. Referring to the significance of the marine fisheries sector, the DG said ICAR-CMFRI is playing a major role in the development of the sector which is crucial for blue revolution.
He also released a book ‘The Enigmatic Indian Oil Sardine: An Insight’ authored by leading scientists of ICAR-CMFRI and posters on major edible and ornamental fishes of Lakshadweep Islands prepared by the Institute.

About 30 kg of the depurated meat was obtained and the same was sold at the rate of Rs.200/- per kg, and the proceeds were handed over to the women participants. On this occasion, a brochure highlighting the nutritive value of the bivalves, prepared in regional language (Tamil) was released by the Joint Director of Fisheries.
ICAR-CMFRI trains youth to become entrepreneurs through cage fish farming
In a major effort which is beneficial to hundreds of families in Kadamakkudy panchayat, the ICAR- Central Marine Fisheries Research Institute (CMFRI) conducted a three-day skill development programme to the youth in the panchayat to help them become small-scale entrepreneurs in cage fish farming from 23rd to 25th February 2019.
Jointly with the Korampadam Service Co-operative Bank, Kothad, the ICAR-CMFRI provided them training in various stages of cage fish farming such as cage fabrication, site identification, species selection, feed management, harvest and marketing. As many as 114 villagers attended the training that also included visits to cage farming sites and practical lessons. The collaborative programme has been linked with ICAR-CMFRI’s ongoing project launched last year aiming to train 5000 fishermen across the country in practicing cage fish farming with the financial assistance of the National Fisheries Development Board (NFDB).
In further step to promote the cage farming enterprises in the backwaters of the panchayat, the ICAR-CMFRI will offer all the technical guidance to the villagers while the Bank will give them loan as initial capital to those starting the cage fish farming. The CMFRI will extend technical support to the farmers on each phases of the cage farming to empower them becoming entrepreneurs in the field. Cage fish farming will act as a source for additional income to the fishermen and it will help increase the domestic fish production as well. Species such as cobia, seabass, snappers, mullet and pearl spot will be used for cage farming.
The ICAR- CMFRI has so far trained 2500 fishermen all over the country, and around 2500 cage fish farming units are currently operational across the coastal states under CMFRI’s technical guidance.
Tuticorin Research Centre Conducts Skill Development Programme on Open Sea Cage Farming

In a major effort to increase the marine production, the ICAR-Central Marine Fisheries Research Institute (CMFRI) released seeds of shrimp, cuttlefish and squid into the sea on 7th March 2019. The Mandapam Regional Centre of the ICAR-CMFRI released a total of 11 lakhs seeds of green tiger shrimp (Penaeus semisulcatus) was released at Villundi Theertham, Palk Bay, while the Tuticorin Research Centre of the Institute conducted the sea ranching of cuttlefish (Sepia pharaonis) and squid (Sepioteuthis lessoniana) at Tuticorin. A regular activity of the ICAR-CMFRI, the sea ranching is aimed at increasing the production of these species to ensure the livelihood of fishermen in the regions. This will also help conserving and maintaining the sustainability of the stocks in the wild.
Shri. K. Veera Raghava Rao I.A.S. District Collector of Ramanathapuram was the chief guest of the sea ranching programme by the Mandapam Regional Centre. The shrimp seeds were released in the presence of Shri. K. Muraleedharan, Member, Institute Management Committee of ICAR-CMFRI, leaders of fishermen associations, Dr. R. Jayakumar, Scientist-in-Charge, officials of State Fisheries Department, scientists and staff of Mandapam Regional Centre of ICAR-CMFRI. When the fishermen venture into the sea for fishing after fishing ban period, these shrimps will be available to support their livelihood. During 2017-18, the Mandapam Centre had released 1.7 million seeds of green tiger shrimp into the sea in Gulf of Mannar and Palk Bay region and 1.4 million seeds of the species in 2018-19 at Kunthukal (Gulf of Mannar) and Sangumal (Palk Bay).
Smt. N. Chandra, Joint Director of Fisheries (Regional), Tamil Nadu State Fisheries Department, Thoothukudi was present on the occasion of the sea ranching carried out by Tuticorin Research Centre of CMFRI.

Sea ranching of the hatchery reared cephalopod juveniles
In India, cephalopod fishery is gaining momentum day by day due to the increase in demand of squids and cuttlefishes from international export market leading to fishing pressure on cephalopod resources. At this juncture, attempt to supplement the existing fishery by means of regularly sea ranching will have a positive impact on replenishing the stock of cephalopods. Scientists while monitoring the cephalopod fishery and also enquiries from fishermen engaged in cephalopod fishery revealed that cephalopod egg masses are accidentally entangled in the fishing net and brought ashore and leading to destruction of egg masses. Hence, an attempt was made to collect possible numbers of viable eggs from the fishermen and transported them using aerated containers to Shellfish hatchery of TRC of CMFRI and reared to produce the juveniles from the egg masses and sea ranch them into fishing grounds.
The egg masses were collected and maintained in the hatchery species wise separately in well aerated 1 ton capacity FRP tanks and carefully monitored for hatching. In both Sepioteuthis lessoniana and Sepia pharaonis regular batch hatching is noticed in the hatchery. Newly hatched young ones were collected and stocked in rearing tanks and are fed with appropriate sized live-feed, i.e. mysids, ad libitum to the young cephalopods. The hatchlings of Sepioteuthis lessoniana and Sepia pharaonis were reared 30 and 40 days respectively. The hatchery grown juveniles were handed over to the fishermen in 10 litres aerated polythene bags for further release in the actual fishing ground. This programme is continuing since 2015 at Tuticorin.
