Eight-hundred forty seven specimens measuring 7.4 to 22.8 cm TL, and weighing between 15.0 -216 g total weight were analysed for the study. The length-weight relationships were found to be significantly different between the sexes (P<0.001). The coefficients ‘ a’, ‘b’ of the length-weight relationship were estimated as 0.0333, 2.7919 (r 2 = 0.961) for females and 0.0194, 2.9791 (r 2 = 0.962) for males and the species follows a negative allometric growth pattern (b<3). The fish attains maturity (TL 50 ) at 12.5 cm TL for females and 11.5 cm TL for males. P. aspinosa was found to breed throughout the year with peak spawning during August-September and January. The overall sex ratio (M:F) favoured females at the rate of 1:1.15. A seven-stage maturity was found and a progressive increase in the size of the ova was traced to advanced stages of maturity. The total fecundity of P. aspinosa ranged from 45,823 (12.3 cm TL; 41g body weight) to 1,56,308 (22.8 cm TL; 216 g body weight) with an average fecundity of 84,367 eggs. Analysis of the stomach contents (%IRI) revealed that P. aspinosa mainly fed on Saurida tumbil (%IRI=18.2), followed by Penaeus indicus (%IRI=16.7), Loligo spp. (%IRI=15.2), Squilla (%IRI=6.4), and Acetes spp (%IRI=2.7). Other detailed biological observations such as the length composition, sex ratio, and length at maturity (TL 50 ) of P. aspinosa are also provided in the study. Since the species has been poorly studied and assessed as Least Concern (LC) in the IUCN red list criterion, it is expected that the biological information from the present study will support the ongoing data generation and help in arriving at management decisions for the species in the future.","PeriodicalId":93791,"journal":{"name":"Journal of the Marine Biological Association of India.

The mono-algal diets were Chaetoceros calcitrans, Isochrysis galbana, Chlorella marina and Nannochloropsis oculata. Present work was carried out in a Completely Randomized Design (CRD) with four treatments and three replicates. After feeding O. similis with the 4 algal diets for 25 days, population density of adults, copepodites, nauplii and egg bearers were determined. Density and population growth rate of all stages were the maximum when fed with C. calcitrans and it was confirmed as an excellent diet for O. similis. Growth performance as indicated by population density and growth rate was significantly (P<0.05) higher for all stages when fed with C. calcitrans compared to the rest of the diets. The biochemical profile of O. similis showed superiority in protein (55.6%), and lipid (33.4%) contents on feeding with C. calcitrans. Since the strain is cultivable with good nutritional profile and high survival rate, it gives an immense scope of high value larval feed for use in marine hatcheries. Based on the current results, it is suggested that among the diets tested, the diatom C.calcitrans was the best for enhanced production of all stages of O. similis in controlled conditions followed by I. galbana","PeriodicalId":93791,"journal":{"name":"Journal of the Marine Biological Association of India.

Shifts of species distribution towards the northern latitudes are evident in many seas. The Northern Indian Ocean is warming at an alarming rate as compared to the other oceans. The increased rate of warming will cause substantial responses in the distribution of the pelagic fish species. Many fishes of the family Clupeidae form the mainstay of the marine fisheries of the countries bordering the Northern Indian Ocean. Nematalosa nasus is one of the important pelagic fish found in the region. This study tries to understand the distributional shifts of this species from the region in two future climate scenarios (RCP 6.0 & 8.5). The results indicate a higher influence of the current vector and mean temperature on the distribution of this species. A northward shift in the distribution range is observed in both the future scenarios as compared to the predicted current distribution.","PeriodicalId":93791,"journal":{"name":"Journal of the Marine Biological Association of India.

A total of 26 species belonging to 9 orders and 20 families were recorded from the Kali Estuary and the order Perciformes with 16 species dominated the group (62%) followed by order Mugilliformes and Pleuronectiformes (8%). Maximum abundance was observed during the pre-monsoon season in all the stations. Excluding Ambassis ambassis which was abundant in all the stations, Caranx ignobilis dominated in all the stations. Truly marine and estuarine species of fishes recorded dominated than the freshwater estuarine ones like Etroplus suratensis, Scatophagus argus, Aplocheilus lineatus. Number of species recorded at each station during the study ranged from 11 to 25 and it was significantly different between stations. The Shannon- Wiener diversity index ranged from 2.0 to 4.6, the minimum in station 1 and maximum in station 3. The seasonal analysis of diversity also showed minimum value during the monsoon season in station 1 and maximum value in station 3. The minimum value (2.2) of Margalef richness index was also recorded in Station 1 during monsoon season and maximum value (4.2) in Station 2. When comparing the relative abundance using Pielou’s evenness index (J’) the values were in the range of 0.92 to 0.99 which was closer to one, indicating evenness in distribution. There was similarity in species composition according to different seasons except for monsoon season in Station 1. The same pattern was also evident in the MDS plot where seasonal aggregation was observed between the stations. In addition to the diversity studies, the surveys also threw light on the abundance and seasonality of candidate species suitable for mariculture like C. ignobilis, Lutjanus spp., Etroplus spp., etc. Judicious exploitation of the species could help brackishwater fish farmers.","PeriodicalId":93791,"journal":{"name":"Journal of the Marine Biological Association of India.
