Unprecedented heavy landings of juvenile Kiddy shrimp, Parapenaeopsis stylifera along Karnataka coast

Parapenaeopsis stylifera is one of the most abundant and highly valued shrimp species in India. It forms about 20% of the penaeid shrimp catch of Karnataka with the period from January to June contributing the majority of the catch. In general, the post-monsoon months of August to December is considered as a lean period for P. stylifera. During this period single day fishing trawlers land catch of a mixture of fish, prawns, stomatopods and other crustaceans. The contribution of prawns in the catch is around 10 to 20%

Heavy landings of Sardinella longiceps by purseseiners at Malpe Fisheries Harbour, Karnataka

Malabar coast is well known for oilsardine and mackerel fishery. The oilsardine fishery along the coast is characterised by annual fluctuations in landings (Fig.1). Mangalore and Malpe fisheries harbours are the major oilsardine landing centres of Karnataka. Malpe Fisheries Harbour contributes 40-65% to the total oilsardine landings in Karnataka

Cutting remains from Fish Cutting Centres - A feed source for fish farming in estuaries of Karnataka

Demonstration of small scale cage culture of finfishes in coastal waters initiated by Mangalore Research Centre of ICAR- CMFRI during 2008- 2009 period has resulted in large scale adoption of the technology (Fig.1). The fish production through finfish culture in small cages in Uppunda village of Udupi district in Karnataka increased from an estimated 1.2 tonnes (t) during the 2009-10 period to 14 t in 2013-14. The success of cage farming in estuarine areas which was launched as a pilot project in Uppunda village of Udupi district has extended to other estuaries

Experimental studies on Macro fouling communities on net panels at marine cage farm of Karwar, India

A study was undertaken on the fouling pattern, monthly settlement and species dominance at marine cage culture during the year 2014-2015. The net panels deployed at three different depths during December 2014 and the study was carried out for seven months. The study revealed wide variations in colonization of the bio-foulers, the density varied between 2-260/cm2. The overall density was found to be more in bottom panels (6mt) compared to the top (1mt) and middle panels (3mt). The overall dominant species were hydroids and barnacles throughout the culture period. In the top panels, hydroids were dominant (91.67%) during December, followed by barnacles and amphipods. Additionally, complete dominance of barnacles was observed in the middle panel during May. Barnacles were found dominant (93.75%) on the bottom panels during March, followed by hydroids and crabs. The study underscored that barnacles formed a major contribution of the fouling organisms throughout the culture period. Significant variation in the occurrence and abundance of fouling organisms was observed, between the depths at cage sit

Heavy landing of Charybdis smithii and need for proper utilization

Heavy landings of Charybdis smithii during the January to March, 2020 was documented in Mangalore fisheries harbour. These crabs were the part of trawl discards as geo-coded in situ data collection on trawl discards showed that C. smithii was available along Karnataka coast during August to December and in May as pelagic or semi-pelagic shoals from a depth range of more than 100 m. Landing of this species in Fisheries Harbours was generally rare since there was very limited market demand for these crab

Seasonal and annual variations in fish and macro-crustacean fauna in the shore seine fishery of Karwar, Karnataka

Karwar coast of Karnataka is known for sandy beaches, and these beaches apart from providing the aesthetic beauty, are supporting traditional fishermen of the coast for finding their livelihood avenues. Traditionally the beaches of Karwar is known for shore-seine operations, known as rampani fishery. Rampani nets were made of coir ropes and the nets were operated from October to March, exclusively targeting mackerel and sardines

Exploitation of the non-conventional bullseye fishery resource in Karnataka

The estimated average all India marine fish landings during 2012-2016 was 36,71,651 t. Of late, the catch of priacanthids has increased in commercial landings all along Indian coast. The bullseye contribution to the total production which was 0.3% in 2011 increased to 3.6% during 2016 and increased by two times from an annual average 23,031 t (2007-2011) to 45,544 t in 2012-2016. Nearly 94% production was from the west coast

Shift in diet composition of Indian mackerel Rastrelliger kanagurta - an analysis in relation to climate change

The feeding regime of organisms depend on the plankton community structure which is being studied worldwide to assess the changes in marine ecosystem structure due to climate change or anthropogenic activities. An attempt is made here to study the seasonal and long term variation in feed composition of Indian mackerel over a period of 40 years and its relationship with sea surface temperature to elucidate structural changes in food composition if any over period of time and its relationship to the primary and secondary productivity in eastern Arabian Sea marine ecosystem. The diet study during 2011-2014 reported the domination of phytoplankton consisting of Coscinodiscus sp. consistently and the presence of macroplankton and fish larvae whereas the diet during 1960-1961 showed the dominance of zooplankton and copepods. It could be assumed that increase in sea surface temperature which resulted in dominance of phytoplankton community as reported elsewhere in the world is also observed in eastern Arabian Sea which is reflected in the diet regime of Indian mackerel. The results also indicate its facultative feeding behaviour by compensating the low value phytoplankton with high value macroplankton and hence can be considered as a resilient species with regard to climate change
