Assessing changes shoreline in Dayyer city using the landsat satellite data, sensor TM and OLI 1991 and 2014 years
Get PDFCoastal environments are considered the most sensitive system environments. In terms of environmental Coastal areas because of the sensitive and productive ecosystems have high importance and value. Having knowledge of the coastline’s behavior can help of the coastal better management. The aim of this study is to assessing the application of the OIF utility index factor in the assessment of coastline changes in Dayyer city, Using Landsat satellite images sensor TM and OLI 1991 and 2014 and the software are 2013®MATLAB and ArcGis 9.3. For the separation of land and water, OIF index value for all different band combinations in the application MATLAB® 2013 was calculated and then high-pass Sobel filter with 3 × 3 masks was applied to the images. Then digitization process during different periods in application environments ArcGis 9.3 was done manually and with high precision. The results of the survey the coastline from 1991 to 2014 show moving the coastline to the sea side (sedimentation) and landward (erosion), Which totals 33/784 square kilometers sedimentation and 9/132 square kilometers erosion shows from 1991 to 2014, in Dayyer city occurred because of the construction of piers, installations manmade and natural factors
Nitrogen and phosphorous budgets for integrated culture of whiteleg shrimp Litopenaeus vannamei with red seaweed Gracilaria corticata in zero water exchange system
Get PDFIn this study, a 2×3 factorial design with two levels of shrimp density (25 and 50 shrimp per m2) and three levels of red algae density (0, 200 and 400g per m2) was applied to calculate nitrogen and phosphorous budgets in the integrated culture of Litopenaeus vannamei with Gracilaria corticata during 45 days in a zero water exchange system. Juveniles of L. vannamei (5.82±0.11 g) and G. corticata were cultured in 18 round 1 m3 poly ethylene tanks. Water temperature, dissolved oxygen (DO), pH and salinity were measured once every 3 days. Results indicated that shrimp density had a significant effect on pH and DO in the morning and in the afternoon. The algal density didn’t have a significant effect on pH and DO in culturing tanks (p> 0.05). According to the results of this study, the main source of nitrogen and phosphorus input to the tanks during a 45-day culturing period was from feeds. Shrimp and algal densities significantly affect the concentration of total ammonia, nitrite, nitrate and phosphate in water and an increase in shrimp density led to an increase of these compounds whereas, increasing the algal density led to the reduction of these compounds. Results indicated that increasing the density of G. corticata in all treatments, led to an increase in biomass of harvested shrimp and the co-culture of G. corticata with L. vannamei decreased the amount of nitrogen and phosphorus in both water and sediments and improved the water quality of L. vannamei culture

New host record for parasitic copepod, Lamproglena chinensis Yü, 1937 from marine fish Pampus argenteus
Get PDFA copepod parasite, Lamproglena chinensis Yü, 1937 was recorded first time from its new marine host Pampus argenteus captured from the coastal waters of Pakistan. This is the first report on the occurrence of Lamproglena chinensis in marine fish in the World. Lamproglena chinensis was reported to parasitize only freshwater fishes in many countries of the world. This species was reported previously to parasitize freshwater fish from Pakistan. The present paper provides the description of Lamproglena chinensis collected from the gill filaments of Pampus argenteus
Report of the national workshop on small-scale fisheries, Cyclone Ockhi and disaster risk management 29 to 30 May, 2018, Thiruvananthapuram, Kerala, India
Get PDFNational Workshop on Small-scale Fisheries, Cyclone Ockhi and Disaster Risk Management was held on 28 to 29 May, 2018 at Thiruvananthapuram. The workshop was organised by the International Collective in Support of Fishworkers (ICSF) Trust with the support of the Food and Agriculture Organization of the United Nations (FAO). The workshop was attended by a large number of distinguished participants, including fishworker organisations, government officials, academics, non-governmental organisations, civil society organisations and the disaster affected community. Representatives from FAO and the Bay of Bengal Programme Inter-Governmental Organisation (BOBP-IGO) also attended the programme. On 29 November 2017, a deep depression, detected in the Indian Ocean southwest of Sri Lanka, rapidly intensified into a cyclonic storm off the coast of Tamil Nadu and Kerala and the Union Territory of Lakshadweep Islands. Cyclone Ockhi, as it was named, took the life of a number of fishers, injured many and destroyed fishing vessels and gear
COFI: not a small focus
Get PDFWith a record participation, the Thirty-third Session of the FAO Committee on Fisheries (COFI) managed to integrate small-scale fisheries issues into almost all agenda items. The Thirty-third Session of the Committee on Fisheries (COFI) of the Food and Agriculture Organization of the United Nations (FAO), held in July 2018, saw a record participation. There were 760 delegates representing member countries, and many representing non-governmental organizations (NGOs) and intergovernmental organizations (IGOs). Small-scale fisheries issues were integrated into almost all agenda items of the meet
