Enhancing capacities of fishing communities: ICSF-BOBLME sub-regional dialogue on labour, migration and fisheries management. Report of the proceedings, 11 to 13 December 2013, Chulalongkorn University,Thailand

This report on the “Sub-regional Dialogue on Labour, Migration and Fisheries Management”, held at Chulalongkorn University, Bangkok, Thailand, from 11 to 13 December 2013, highlights the issue of migrant labour on board fishing vessels and the problems migrant workers face in their workaday lives. This report will be useful for students, researchers, activists and anyone else interested in matters related to fisheries and small-scale fishing communities.

On the design, operation and efficiency of 11 m dual purpose trawl for small machanised [i.e. mechanised] boats

Preliminary midwater fishing trials were conducted off Cochin with an 11m dual purpose trawl during the monsoon months when the prawns were available in the column layers. Further, with a view to assess its suitability as bottom trawl, the gear with suitable modifications in the rigging was towed in comparison with a 15m bottom trawl along the depth ranges of 5-10m and 10-20m and the fishing operations were found satisfactory.

细胞色素b基因序列与11种熊蜂的系统进化

通过比较一段357bp的细胞色素b的序列,分析了熊蜂属5亚属11种熊蜂系统发育关系。5亚属包括Bombus(5种)、Thoracobombus(3种)、Mendacibombus(1种)、Fervidobombus(1种)和Pyrobombus(1种)。该序列有65个单变异多态位点和71个简约信息多态位点,翻译成119个氨基酸序列后有45个氨基酸变异位点。根据P-距离构建的邻接树(NJ tree)和最大简约树(MP tree)都显示同样的结果:Mendacibombus(B. avinovielllus)分化最早;Fervidobombus(B. pensylvanicus)次之;Pyrobombus(B. impatiens)和Bombus形成姊妹群;Bombus亚属是单系群,其中B. ignitus在所研究的5个种中分化最早。

The effect of increase in the number of fishing trips on the economic efficiency of 9.82 m and 11 m fishing trawlers along Kerala coast

Cost-benefit analysis of a 9.82 m and 11 m fishing trawlers based on the number of fishing trips is presented. The number of fishing trips per year determines the profit and loss of the trawler. With the increase in the number of fishing trips, the profit also increase for both the sizes of trawlers. The minimum quantity of prawn and fish to be landed for 0-20% profit for varying number of fishing trips are worked out. The break-even for 9.82 and 11m trawlers was observed to be 185 and 210 fishing trips respectively during 1980-81.

Impact of plankton structure on primary productivity in two beels of West Bengal, India

Planktonic community in floodplain wetlands embodies the energy transfer through this phase and indicates trophic status of lake. Originally rich bottom coupled with a conducive physicochemical environment encourages fast colonization of the plankton population. Present investigation was carried out in two floodplain wetlands having characteristics of open (Amda beel) and closed (Suguna beel) system. The physicochemical parameters of water and soil of the investigated heels were by and large conducive for planktonic growth. The density of plankton population varied between 1,346 and 2,170 u/l in Suguna bed whereas in Amda beel it ranged from 1,030 to 1,802 u/l. Seasonal fluctuations in water column were conspicuous and mostly dependent on the replenished resources and volume, A mixed and balanced population of diversified fauna constituted the plankton population of the investigated ecosystems. Mostly the diversity was observed to be maximum during winter seasons with coincidence of favorable temperature, dissolved oxygen and other physico-chemical parameters of water besides optimum solar penetration. Richness of planktonic structure in closed system (Suguna) resulted in higher fish production (1,570,05 kg/ha/yr) than that of open system (Amda) (384.4 kg/ha/yr).

BOBLME Mergui Archipelago Stakeholder Workshop, Yangon, Myanmar, 11-12 October, 2010

Updating environmental baselines and information; identification of major gaps; promotion of environmental services; promotion of livelihood interests; systematic monitoring practices; and increasing public awareness

Report of the Marine Protected Areas Working Group meeting, Penang, Malaysia, 11-12 February, 2014

The objectives of the workshop were to review and update Marine Protected Area (MPA) data, finalise policy briefs for each country and recommend future actions and policies for sustainable management of MPAs.

Detour behavior changes associated with prenatal morphine exposure in 11-day-old chicks

The central nervous system exhibits remarkable plasticity in early life. Prenatal morphine exposure may induce adverse behavioral effects on the neonate and the developing offspring. In the present study, we investigated the effect of prenatal morphine exposure (daily from embryonic days 12-16, 20 mg/kg) on 11-day-old chicks using two forms of spatial paradigms: one trial detour behavior task in which animals must bypass an obstacle to reach the desired goal without any training and detour learning task which required several trials of training to reach the detour criterion. The results showed that, on the condition that chicks could successfully detour in the first trial, morphine exposed chicks exhibited longer detour latency to finish the task, coupled by a preference for turning right versus turning left. In contrast, no significant difference in learning and memory was found in detour learning task between morphine exposed chicks and saline chicks. These findings suggest specific behavioral changes associated with prenatal exposure to opioids during mid to late gestation, also raise attention to the possible health hazard from pregnancy drug use in everyday life.

Report of the training programme on Essential Ecosystem Approach to Fisheries Management (EAFM): developing capacity in the EAFM, Chennai, India, 11-16 August, 2014

Participants were exposed to concepts and information about EAFM using a structured, participatory method of delivery. The learning strategy involved specifically designed exercises, using real examples, to consolidate learning. Daily monitoring and reviews were conducted together with pre-and post-course assessment.
