The technology comprises captive broodstock development, induced breeding and larval rearing in captivity.

ICAR-Central Institute of Fisheries Education, Mumbai developed the compressive package of captive seed production of peacock eel. The technology comprises captive broodstock development, induced breeding and larval rearing in captivity. In captivity, Peacock eel attain sexual maturity at the size of 18-25 g which is obtained after one year of rearing. Mature oozing males and gravid females were noticed in the mid of June 2024. The technology was developed by a team of scientists: Dr. Prem Kumar, Dr. S. Munilkumar, Dr. Rupam Sharma, and Dr. K.N. Mohanta.

Macrognathus aral (Peacock eel) is a commercially important fish species of mastacembelidae family. It is an important food fish of North-East India, Bihar and Jharkhand. Due to consumer demands and high nutritional value, it fetches a high market price between Rs. 500-600/kg. It also has very high ornamental value due to its attractive colour pattern, body shape and playful behaviour.

During the first week of July 2024, female fish (average body weight, 22 g) having the mean oocyte diameter of 1.45 mm and oozing males (average body weight, 14 g) in sex ratio of 2:1 (Male: Female) were selected and administered with an inducing hormone (a combination of LHRHa and domperidone) at the dose of 200 µl to female and half the dose to males. After an 18 h of average latency period, spawning was observed. The estimated functional fecundity of a female was around 3500. Fertilised eggs of Peacock eel were greenish, spherical, and adhesive in nature. The root of the Pistia plant was used as a substrate for the sticky eggs of the Peacock eel. Estimated fertilization and hatching rate were 45 and 20 per cent, respectively.

The larvae hatched out after an incubation period of 18 h at 28 0C water temperature. The newly hatched larvae measured from 1.65 to 1.85 mm with a large oval-shaped yolk sac. During nursery rearing, newly hatched larvae were transferred to outdoor tanks having floated aquatic plants (Pistia) as hideouts. The yolk sac was utilised after five days post-hatching (dph). Exogenous feeding was initiated after five dph with Artemia nauplii. which continued for 30 days. Weaning on a micro-particulate diet was started at 30 dph. Fry produced are being reared in outdoor tanks.

 It will facilitate microalgae biomass production throughout the year including rainy season when outdoor cultivation is hindered due to low light and rainwater.

ICAR-Central Institute of Fisheries Education, Mumbai transferred a technology for microalgae biomass production using a Photobioreactor developed by ICAR-CIFE to Phoenix Agrotech LLP, Mumbai.

The agreement was signed by Dr C.N. Ravishankar, Director/Vice-Chancellor, ICAR-CIFE and Vinit Rathod, CEO, Phoenix Agrotech LLP on behalf of the respective organizations. The technology was transferred in a non-exclusive mode.

The newly designed Photobioreator enables optimum utilization of natural light through a tubular module installed under outdoor conditions. The Photobioreactor also consists of an integrated harvesting module and LED light panels for illumination of indoor culture tank. The novel design of Photobioreactor facilitates microalgae biomass production throughout the year including rainy season when outdoor cultivation is hindered due to low light and rainwater accumulation in open culture systems.

A team of scientists will guide the industry for realizing the potential of technology and will provide necessary training and technical know-how.

The feed mill will look into different feed ingredients for the Fish Feed preparation

Jatindra Nath Swain, Secretary (Fisheries), Department of Fisheries, Ministry of Fisheries, Animal Husbandry & Dairying, Government of India inaugurated the Mobile Feed Mill (CIFE Model) developed by the FNBP Division, ICAR-Central Institute of Fisheries Education, Mumbai, Maharashtra. Swain stressed the capacity of Mobile Feed Mill and the use of the different feed ingredients for the Fish Feed preparation.

Dr Joykrushna Jena, Deputy Director General (Fisheries Science), ICAR; Dr C Suvarna, CEO, National Fisheries Development Board, Hyderabad; Dr Ravishankar CN, Director, ICAR-CIFE, Mumbai; Dr NP Sahu, Joint Director, ICAR-CIFE, Mumbai; Dr Parimal Sardar, HoD, FNBP Division, ICAR-CIFE, Mumbai and Principal Scientists, FNBP Division, ICAR-CIFE participated in the event.

Dr Sikendra Kumar, Scientist, ICAR-CIFE, Mumbai underlined the features of the Mobile Feed Mill having capacity of making 40 kgs Pelleted Feed per Hour. He stated that the Mill developed under the Tribal Sub Plan Scheme will cater to the need of the marginal farmers for making feed using the available ingredients with them at the pond site itself of the tribal farmers. This will enhance the aquaculture productivity of the farmers.
