On the occurence of 'wahoo' Acanthocybium solandri in the hooks and line catches off Lawsons Bay, Visakhapattinam

The occurrence of Acanthocybium solandri in the hooks and line catches off Lawsons Bay was noticed in1988 and 1990. The specimen was infested with the parasitic copepod of the genus Lernaeenicus, almost similar to L. seeri. The occurrence of A. solandri off the north coast of Andhra as reported now confines to the period October - March. This is the period when a strong surface current from the Malasian region enters the south-east corner of Bay of Bengal,bringing the equatorial Indo-Pacific waters.Wahoo' probably enters the Bay of Bengal along with this current and moves along with the prevaling currents on the east coast of India during October – March

Pollution from fishmeal plant discharge at Mukka beach, north of Mangalore

Effluents from various industries are major source of pollutants in the coastal areas. The type and pollution and the impact magnitude of on coastal environment depends on the physical and chemical characteristics of the effluent, the mode of discharge and the hydrodynamics of the receiving body. While several chemical manufacturing industries produce toxic effluents which need special treatment and disposal, the process wastewater from fish/food processing units have high organic content which can be removed by simple methods

Influences of nutrition information on fast food consumption among undergraduates

© 2018 The Authors. This study was carried out to determine the influences of providing nutrition information on fast food restaurant menus, especially among Malaysian undergraduates, who often eat outside the campus during the semester. A validated questionnaire, adapted from previous studies was used to determine the general perception of nutrition information and nutrient intake when eating at fast food restaurants. A total of 185 undergraduates from three different schools participated-medical sciences (n=54, 29.2%), dentistry, (n=54, 29.2%), health sciences (n= 77, 41.6%) in a university. In general, the majority of the undergraduates ate fast food at least once a week (n= 105, 56.8%) and most of them preferred to eat outside on weekends (n=156, 84.3%). Majority perceived that it was important to provide nutrition information at fast food restaurant (n=183, 98.9%). The mean for calorie, fat and sodium composition of their food choices were significantly different between before and after providing nutrition information of food items that they intended to purchase (p<0.001). Student’s intention to purchase definitely differed when they were well informed about the nutrition value of food

Optimization of certain physical parameters for the mariculture of Gracilaria edulis (Gmelin) Silva in Minicoy lagoon (Laccadive Archipelago)

Mariculture of the agar-yielding, red seaweed, Gracilaria edulis (Rhodophyta) was conducted in Minicoy lagoon during 1990–1992. Experiments were conducted on dry matter accumulation, effects of planting density, depth of water above culture nets, periodic cleaning for removal of epiphytes, grazing and the yield as well as regeneration of G. edulis after successive harvests to understand the optimum requirements of this seaweed. Six culture methods were tested and the yields obtained were compared to arrive at a culture method suitable for Minicoy lagoon

Rhodamine B Adsorption- Kinetic, Mechanistic and Thermodynamic Studies

Adsorption of rhodamine B from aqueous solution on the surface of Moringa oliefera bark carbon was accomplished under the optimize conditions of temperature, concentration, pH, contact time and quantity of adsorbent. Spectrometric technique was used for the measurements of concentration of dye before and after adsorption. The percentage removal of rhodamine B was calculated. The values of % adsorption data for Moringa oliefera bark carbon system show better adsorption capacity. The experimental data are fitted to the Langmuir and Freundlich isotherm equations. The values of their corresponding constant were determined from the slope and intercepts of their respective plots. Thermodynamic parameters like ΔG0, ΔH0 and ΔS0 were calculated. Rhodamine B-Moringa oliefera bark carbon system shows spontaneous and endothermic behaviour. The results of these investigations suggested that natural adsorbents can be utilized as adsorbent materials, because of their selectivity's for the removal of dyes

Fecundity and viability of eggs in wild breeders of spiny lobsters, Panulirus homarus (Linnaeus, 1758), Panulirus versicolor (Latrielle, 1804) and Panulirus ornatus (Fabricius, 1798)

Berried lobsters collected from landing centres and lobster holding centres were used for larval rearing of the spiny lobsters, Panulirus homarus (Linnaeus, 1758), Panulirus ornatus (Fabricius, 1798) and Panulirus versicolor (Latrielle, 1804). Fecundity of the lobsters used for larval rearing was calculated as the number of eggs deposited on the ovigerous setae on the pleopods. The number of eggs in a single brood ranged from 1,20,544 to 4,49,585 in P. homarus. 5,18,181 to P.ornatus 1,979,522 and that of P. versicolor as 1,70,212 to P.versicolor 7,33,752. The tropical lobsters are reported to and therefore breed two times or more in a year. The absolute (annual) fecundity of these lobsters is expected to be higher. The phyllosoma larvae released, as percentage of fecundity, was maximum in P. homarus 85.7, 49.7 in P. ornatus and 74.0 in P. versicolor. Handling of lobsters at the landing and holding centres and aerial transport resulted in high percentage of eggs in arrested development, complete or partial shedding of eggs and release of weak phyllosoma larvae. Severe bacterial infection leading to complete shedding of eggs was recorded in a few breeders collected from holding centres

Growth, maturity and mortality of Upeneus sulphureus from Andhra - Orissa coast

The length weight relationship, relative condition factor, growth, maturity, mortality and exploitation ratio of Upeneus sulphureus (cuv.) from Andhra-Orissa coast were studied. Growth parameters estimated from von Bertilanfly's growth function were: La, 20.22 cm; K, 0.65846/year; and to, —0.284 years. The fish attained maturity at 131 mm and had a longevity of 4.56 years. The total mortality Z and the fishing mortality F wore estimated as 2.318/year and 0.826/year respectively. The exploitation ratio E at 0.356 indicated under-exploited state of the stock

“We want more”: perspectives of sarcopenic older women on the feasibility of high-intensity progressive resistance exercises and a whey-protein nutrition intervention

This qualitative study is nested within a 12-week pilot randomized-controlled, two-arm trial involving high-intensity progressive resistance training (PRT) or PRT with a multi-nutrient, whey-protein supplementation (PRT+WP) in sarcopenic older adults (trial registration no: TCTR20230703001). The aim was to investigate sarcopenic participants' perceptions and barriers to this multi-modal intervention strategy that may accelerate “real-world” implementation. Eighteen older adults (one man) with possible sarcopenia were invited to join the study, of whom 16 women were randomized to a thrice-weekly PRT (n = 8) program (80% of 1-repetitive maximum, six resistance band exercises) only or PRT plus daily weekday milk-based WP supplementation (PRT+WP, n = 8). Muscle strength (handgrip and 5-times sit-to-stand), mass (dual-energy X-ray absorptiometry), performance (Short Physical Performance Battery and stair ascent-descent), and nutrition status (Mini Nutritional Assessment) were assessed for changes. We randomly selected eight women for the semi-structured interview. Post-intervention, eight (50%) women were sarcopenia-free, six (38%) remained in possible sarcopenia, one (6%) improved to sarcopenia, and one (6%) deteriorated from possible to severe sarcopenia. There were no significant between-group differences, but significant within-group improvements (p &lt; 0.05) were detected for handgrip strength (PRT+WP 5.0 kg, d = 0.93; PRT 6.1 kg, d = 0.55), 5-times sit-to-stand time (PRT 2.0 s, d = 1.04), nutrition score (PRT+WP 3.44, d = 0.52; PRT 1.80, d = 0.44), and stair ascent time (PRT+WP 0.97 s, d = 0.77; PRT 0.75 s, d = 0.97). Our thematic analyses identified four main themes, namely, (1) perceived benefits, (2) sustaining behavior changes, (3) challenges in participating, and (4) improved wellbeing. Participants expressed how they initially were skeptical and doubted that they could complete the exercises or tolerate the milk-based WP supplements. However, they reported positive experiences and benefits felt from strength gains, increased confidence, and better physical abilities. Participants were surprised by the zero adverse effects of WP supplements. The women wanted more nutritional information and structured, guided exercise programs and suggested a community-based implementation. In conclusion, our findings showed PRT was well received and may support reduced risks of sarcopenia. No added benefits were seen with the addition of WP supplementation, but a larger sample is required to address this question. Overall, older (previously sarcopenic) Malay women indicated that they want more multi-modal programs embedded in their community

Fishery resources of spiny lobsters in the Andaman Island, India

The Andaman and Nicobar (A&N) Islands is the largest archipelago in the Bay of Bengal. In spite of availability of diverse lobster resources, there is no organised lobster fishing in the Islands. The main objective of the study was to collect baseline data on the lobster resources of the Andaman Island. Periodic field surveys were carried out at 33 landing centres in the Andaman and data were collected by direct observation and questionnaires. Mechanised and non-mechanised fishing crafts are engaged in lobster fishing in the Island. Lobsters are manually caught by spears, gillnet, shoreseine and handpicking. Six commercially important species of spiny lobsters, Panulirus penicillatus, P. versicolor, P. homarus, P. ornatus, P. polyphagus and P. longipes are present in the island. Among them, P. penicillatus dominated the landings throughout the study period (1999-2000), with maximum catch in January, followed by P. versicolor. The total lobster landings in Andaman during the study period were estimated as 3.16 tonnes with maximum landings in south Andaman (Port Blair)
