Seasonal Variation of Groundwater Quality for Irrigational uses in Gadilam River Basin, Tamil Nadu, India
The present research work pertains to the Gadilam river basin groundwater quality for irrigation uses with respect to the Archaean formation, the Quaternary formation, the Tertiary formation and the Cretaceous formation. Experiments were carried out for two seasons (rainy season and summer season) for two successive years (November 2018 and June 2019). Overall, 120 groundwater samples were collected from the Gadilam river basin, excluding the reserved forest area. The 50 samples were collected from the Archaean formation, 34 samples from the Quaternary formation, and 35 samples from the Tertiary Formation. The remaining sample is from the Cretaceous formation. Based on the obtained analysed data, the following agricultural water quality parameters were calculated using the following expressions: The irrigational quality parameters are used, such as sodium percentage (Na%), sodium adsorption ratio (SAR), KellyтАЩs ratio (KR), permeability index (PI), magnesium ratio (MR), residual sodium carbonate (RSC), and potential salinity (PS) are calculated and assessed for irrigation purposes
CMFRI establishes a Pilot Farm in the outfall channel of the Coastal Gujarat Powers Ltd., Mundra, Kutch District, Gujarat
A customized
sea cage for the running waters of the
outfall channel was designed and
fabricated by the scientists of the Regional
Centre, Veraval. Two square cages of 5m
size made of Galvanised Iron pipes of 1.5"
size, with base collars and hand rails was
fabricated at the site and mounted with
the square shape culture nets of suitable
size procured
Fishery and stock assessment of the three-spot swimming crab Portunus sanguinolentus (Herbst, 1783) off Veraval, Gujarat
The fishery and stock characteristics of Portunus sanguinolentus was studied during 2009-2010 from Veraval waters. The average annual landing was 322 t, which constituted about 40% of the total edible crab landings at Veraval. Length-weight relationship showed isometric growth. LтИЮ, K and t0 estimated were 178.7 mm, 1.2 yr-1 and -0.08 yr, respectively. Total mortality rate (Z), fishing mortality rate (F) and natural mortality rate (M) were estimated to be 4.69 yr-1, 2.85 yr-1 and 1.84 yr-1, respectively. The estimated length at capture (L50) and length at maturity (LM50) were 101.33 mm and 96.89 mm, respectively, indicating that the crabs enter into peak exploitation phase after attaining sexual maturity. The species is a continuous spawner and shows peak recruitment during May and August. The current exploitation rate (Ecur) was found to be 0.61 which is equal to E0.1 estimated by Beverton and Holt yield per recruit analysis. Thompson and Bell bio-economic analysis showed that species can be exploited at the present level to maintain the revenue from the fishery at economic level
Improving child survival under National Health Mission in India: Where do we stand?
India contributes to around one-fifth of the global under-five mortality and also maternal mortality besides one-third of the neonatalmortality. Since any reduction in child mortality in India is crucial for the global decline, therefore, the Indian Government decidedto undertake massive correction of the health system. This led to the launch of National Rural Health Mission in the year 2005. Sincethen, significant progress has been made and child mortality rates have shown a sharp decline. On comparing the progress made by theworld toward Millennium Development Goals, India fares better by showing a decline of 46.5% in comparison to 41% for the entireworld during the same period. In order to assess the state-wise reduction, data from sample registration system of the Registrar Generalof India which is available for most of the States/Union Territories (UTs) have been analyzed. States such as Maharashtra, Tamil Nadu,and Kerala have shown an impressive decline but some states such as Himachal Pradesh, Punjab, Mizoram, and Delhi still have a longway to go to reach the state specific goals and targets. Any further decline would only be possible by addressing inter-district variationsthat are still lagging behind and focused efforts need to be made, in order to reach these desired goals. This analysis would be valuablein planning future program implementation plans
Capture based aquaculture of spiny lobster in sea cages: A new livelihood opportunity for the 'sidi' adivasi tribal people in Gujarat, India
Gujarat is one of the most important
maritime states of the country having
the longest coast line of about 1,640 km
and a very broad continental shelf. The
state has been bestowed with highly
productive and diversifi ed ecosystems
and considered as one of the leading
marine fi sh producing states of India,
with fi sheries providing livelihoods for
more than 400,000 people directly and
indirectly. However, over the last few
years the marine fi sh production of the
state has been relatively static at around
half a million tonnes and has been
showing signs of being fully exploited.
However, as the state has a wide
continental self it also has significant
potential for mariculture. Owing to the
economic importance and availability
of seeds of spiny lobster, an open sea
cage culture demonstration of Panulirus
polyphagus was carried out involving
Sidi tribes as a major stakeholder
Experimental cultivation of seaweed Kappaphycus alvarezii using net-tube method
Kappaphycus alvarezii an economically
important red tropical seaweed, is used as
significant source for carrageenan that is used in
various food, pharmaceutical, industrial and
biotechnological applications. The commercial
cultivation of K. alvarezii was initiated in the
Philippines in the year 1960 and later it was
introduced in many countries including India for
experimental or commercial cultivation. The rapid
growth rates, easy dispersal and ways to cultivate
K. alvarezii makes the species adaptable and
flourish in new habitats. It is reported that the
species can double its biomass in 15-30 day

CMFRI establishes sea cage farm off Veraval waters for the "Sidi" tribals of Gujarat
The CMFRI, through the Regional Centre, Veraval have established the first of its kind Sea Cage Farm in the sea off Veraval for the Primitive Tribal Group of Gujarat 'Sidi' as a livelihood development programme under the institutes Tribal Sub Plan Outlay 2012-13
Occurrence of the snapper Paracaesio sordida Abe & Shinohara, 1962 from north-west coast of India
Paracaesio sordida Abe & Shinohara 1962, the
dirty ordure snapper (Family: Lutjanidae), has a wide
