A code list of common marine living resources of the Indian Seas (Revised Edition)
The Central Marine Fisheries Research Institute,
Cochin is the pioneer national establishment primarily engaged
in marine fisheries research in the country. As a programme of
dissemination of information the Institute published a code list
of common marine living resources of the Indian seas in 1983.
However, considerable changes have since occurred in the
nomenclature of many of the genera, families and species of
fishes. Hence it is felt that there is an urgent need to revise the
code list incorporating these changes. The present publication
is a result of this exercise
Code list of common marine living resources of the Indian Seas (With Revised Version)
The Central Marine Fisheries Research Institute has
been estimating marine fish landings along the Indian Coast
for the past three decades and the data are being furnished
to Central and State Governments, Industry, and national
and international agencies. The Institute is also involved
with the assessment of our marine fishery resources and
management of multispecies harvested by diverse fishing
gears. In the years to come, our commercially utilised
marine animal and plant resources may cover not only
conventional fin-and shell-fishes.but also non-conventional
groups, such as mesopelagics, sponges, corals and seaweeds.
There are endangered groups, such as marine
mammals and turtles, which are protected under Wildlife
Act. They occur as incidental catches or are 'occasionally
stranded and these need monitoring
Evaluation of response to combination therapy with enalapril and torasemide in dogs with mitral valve disease
The present study was carried out with the objective of evaluating the response to a
combination therapy of enalapril and torasemide in dogs with mitral valve disease (MVD). Dogs
diagnosed with stage C of MVD as per the American College of Veterinary Internal Medicine
guidelines were included in the study. Treatment was initiated with enalapril at 0.5 mg/kg BID
and torasemide at 0.2 mg/kg OD orally on 0th day. Detailed clinical examination with special
reference to the cardiovascular system including measurement of blood pressure, radiographic,
electrocardiographic and echocardiographic parameters of the animals were performed on 0th and
30th day of treatment. The treatment was well tolerated by all the animals. Amelioration of clinical
signs with a noticeable reduction in cough was noticed in all the animals. On 30th day of treatment,
a significant decrease was noticed in the vertebral heart score and left ventricular internal diameter
during diastole and a non-significant decrease was noticed in left atrium to aortic root ratio, left
ventricular internal diameter during systole, with a considerable reduction in severity of mitral
regurgitation. Post- treatment clearing of lung fields was noticed in dogs with radiographic evidence
of pulmonary oedema on 0th day. In addition to this, ventricular premature complexes noticed in
three animals pre- treatment was not noticed post treatment
Haemato-biochemical and trichographic studies on mucocutaneous lesions in dogs
The present study was carried out with the objective of assessment of haematobiochemical and trichographic features of mucocutaneous lesions in dogs. Dogs presented with mucocutaneous lesions associated with various dermatological conditions were included in the study. Mange, atopic dermatitis, dermatophytosis, juvenile cellulitis, pyoderma and hypothyroidism with secondary Malassezia dermatitis were presented with mucocutaneous lesions in the perioral, periorbital and in the nostrils with least involvement of anogenital region. Haemato-biochemical analysis revealed anaemia, non-significant increase in total leucocyte count, neutrophilia, eosinophilia, elevated platelet count, hyperproteinaemia and hypoalbuminaemia. Elevated serum C-reactive protein was evident in all cases. Trichographic features revealed that highest number of hairs were included in the telogen phase of hair cycle with greater number of primary hairs. Hair fractures were evident in 20.8 per cent of hairs and trichoptilosis of hair tip was observed in 50.8 per cent of hairs studied. Demodex mites could be detected by hair pluck examination in all cases of demodicosis
Evaluation of oxidative stress and efficacy of antioxidant therapy in dogs with haemorrhagic gastroenteritis
The present study was conducted to evaluate the alterations in oxidative stress parameters in dogs suffering from haemorrhagic gastroenteritis (HGE). Dogs presented with vomiting and diarrhoea were screened and fifteen animals with signs suggestive of HGE were included in the study. The oxidative stress parameters, serummalondialdehyde (MDA) level, total antioxidant status (TAS) and plasma glutathione peroxidase (GSH-Px) activity were studied. The values were compared with the values from six apparently healthy dogs. A significant increase was noticed in the mean values of serum MDA and TAS of diseased animals at the time of presentation when compared to healthy animals whereas the activity of plasma GSH-Px was found to be lower than in healthy dogs. Supplementation with N-acetyl cysteine @ 70 mg/kg or five days was found effective in managing the oxidative injury in the affected animals
Evaluation of electrocardiographic and serum biochemical changes in arrhythmias associated with renal diseases of dogs
The present study was conducted to investigate electrocardiographical (ECG) and
haemato-biochemical changes in arrhythmia associated with renal diseases in dogs. The dogs with
renal affections confirmed through appropriate diagnostic methods were selected and screened
for arrhythmia. The ECG and haemato-biochemical parameters of twenty dogs with arrhythmia
were compared with that of the control group and ECG parameters were statistically correlated
with the haemato-biochemical parameters for correlation studies. It was found that the occurrence
of arrhythmia was 51.2 per cent in renal diseases. Arrhythmia was more predominant in dogs with
chronic kidney disease (CKD) followed by acute kidney injury (AKI). Sinus arrhythmia followed by
first-degree AV block and wandering pacemaker were the common types of arrhythmias observed.
A significant increase in R-R interval and a decrease in heart rate was noticed in comparison.
The haemato-biochemical analysis revealed anaemia, leukocytosis with neutrophilia, elevated
blood urea nitrogen (BUN), creatinine and magnesium level. A significant positive correlation was
noticed between haemoglobin, volume of packed red cells (VPRC) and red blood cell count (RBC)
with T amplitude and, creatinine and BUN levels with corrected Q-T interval. A significant negative
correlation was noticed between VPRC, RBC and haemoglobin with the corrected QT interval. The
present study revealed ECG and haemato-biochemical parameters had a significant role in renal
diseases in dogs which might help in the early diagnosis and proper management of arrhythmia
associated with renal diseases
Endocrine Autoimmunity in Association with Female Infertility
Infertility is the inability to conceive after a year of regular unprotected sexual intercourse, affecting 10-15% of couples. Advanced age, obesity, and certain medications can hinder fertility. Endocrine autoimmunity is increasingly recognized as a significant contributor to female infertility, often complicating various gynecological conditions. Autoimmune issues involving the hypothalamus, pituitary gland, thyroid, adrenal glands, and ovaries can impact fertility. A multidisciplinary approach is essential for diagnosing infertility, with a crucial focus on identifying potential endocrine disorders. Here we discuss how to identify endocrine autoimmune patients with ovulatory dysfunction. Women must be advised about limiting factors to be avoided, to protect their fertility. A comprehensive understanding of the underlying mechanisms, coupled with appropriate diagnostic and therapeutic approaches, is crucial for effectively managing this complex condition and helping women achieve their reproductive goals
Saga of inshore prawn fishery of Kerala
The marine shrimp fishery in Kerala existed even before the advent of the Indo-Norwegian project. (INP), but
the genesis of a commercial-scale fishery happened due to the INP. Earlier fished by artisanal crafts and gears,
the introduction of trawlers saw the establishment of shrimps as the major marine fishery commodity. The
penaeid shrimps Metapenaeus dobsoni, Parapenaeopsis stylifera, Penaeus indicus, Metapenaeus monoceros
and Metapenaeus affinis are prominent in the inshore shrimp fishery of the state. Many developmental changes
which happened from time to time in craft and gear technology and the extension of fishing grounds brought
considerable changes in the fishing pattern have influenced the inshore shrimp fishery of Kerala which can be
classified into five phases – primary, growth, declining, enhanced growth and stagnant
Status of marine fisheries of Kerala
Kerala with a coastline of 590 km is a significant
contributor to the total marine fish landings of the
country. A picture of the marine fisheries sector in
Kerala during the years 2005 and 2010 is presented
below (Table 1). With a continental shelf of about
40,000 km2 marine fisheries plays a vital role in
the livelihood of the people
