Note on a bumper catch of Threadfin sea catfish in shore seine

For past several years catfish did not form a fishery at Karwar located in the Uttara Kannada District of Karnataka. However, during the routine observations on the fish landings at Aligadda Fish Landing Centre, Karwar, an unusual bumper catch of about 3 tons of cat fish Arius arius was recorded from shore seine (Yendi bale) in the early hours of 28th July 2018. locally known as "Billi Shade", the catch was so heavy that it was difficult to drag the net to the shore and the haul was partially harvested at sea itself. The net operated by around 40 fishers at a depth of less than 8 metres, was 400 m in length

Incidence of whale strandings in Uttara Kannada, Karnataka

Two instances of the whale strandings were observed in the Uttar Kannada district of Karnataka recently. The first one occurred on 06.05.2017 at Mungodlu, Kumta and the second at Karwar on 18.02.2018. The whale stranded at Mungodlu, near Vannalli village of Kumta Taluk, Uttara Kannada district, Karnataka (14° 26' 034" N and 74° 23' 005" E) was washed ashore in highly decayed condition with its dorsal portion upside down and species could not be identified. The total length of the whale was approximately 9 metres. The vertebrae were found exposed in the beach and a few numbers were collected and preserved in the museum of Karwar Research Centre of ICAR- CMFR

First report on induced spawning of Siganus vermiculatus in India

Siganids are widely distributed to Indo-West Pacific region and the Siganus vermiculatus (Maze rabbit fish/Vermiculated spinefoot) can reach sizes that weigh up 2.3 kg each. It is a species of great aquaculture importance and hence breeding and seed production protocols are necessary. A major breakthrough in the seed production of Siganus vermiculatus by inducing the fishes to spawn under controlled conditions with Human Chorionic Gonadotropin (hCG) during the first quarter of the lunar cycle is reported. The hatchery processes and early larval stages are described

G × E interactions in QTL introgression lines of Spanish-type groundnut (Arachis hypogaea L.)

Multi-environment testing at five locations for rust and late leaf spot (LLS) resistance with 41 introgressed lines (ILs) bred using marker-assisted backcross breeding in the genetic background Spanish- type groundnut varieties identified significant genotype, and genotype 9 environment interactions (GEI) for LLS disease resistance and yield parameters. Significant GEI effects suggest the need to identify location specific breeding lines to achieve gains in pod yield and LLS resistance. The observed variable LLS disease reaction among the ILs in part suggests influence of background genotype on the level of resistance. A breeding scheme with early generation selection using molecular markers followed by phenotyping for LLS, and multi-location testing of fixed breeding lines was optimized to enhance selection intensity and accuracy in groundnut breeding. The ILs, ICGVs 14431, 14436 and 14438 with pooled LLS score at 90 DAS of 3.5–3.7 were superior to respective recurrent parent for pod yield, with early maturing similar to recurrent parents. The pod yield advantage in ILs is attributed by more number of pods, besides resistance to LLS that contributes to better filling

Molecular breeding tools improved drought tolerant groundnut variety for resistance to foliar fungal diseases

A largely rainfed crop in India, drought tolerance, particularly mid- and end-season tolerance, is a key trait in groundnut varieties. A combination of both empirical and trait-based approaches was used in breeding programs of ICAR and ICRISAT, resulting in release of few tolerant varieties that have superior pod yield under drought stress and/or have enhanced water-use-efficiency. There is a need to breed varieties with drought tolerance, disease resistance and quality traits that suit different production ecologies as well as meet the needs of the farmers, consumers and industries. ICRISAT has released an early-maturing (90-95 d) and drought- tolerant variety ICGV 91114 for the drought-prone Ananthapur district of Andhra Pradesh, India, where about 0.7 m ha area is under groundnut cultivation and has low (300 mm) and erratic (30-40 rainy days) rainfall. On-farm studies conducted with ICGV 91114 during 2008-10 showed 30% reduction in yield variability over the years. Following screening in hot-spots of both rust and LLS disease during 2014 rainy season, a total of 27 introgression lines derived from ICGV 91114 were selected and advanced for evaluation in multi-location trials at six locations in 2015 under rainfed conditions. Based on the pod yield under rainfed conditions and disease resistance, three superior introgression lines (ICGV 14410, ICGV 13189, ICGV 14421) were proposed for the first-ever NILs trial (near-isogenic lines trial) along with eight others conducted under All India Coordinated Research Project on Groundnut (AICRP-G) at national level
