(2019) A Review on Techniques and Challenges in the Harvest of Mesopelagics. Fishery Technology 56: 243 - 253

Harvesting of underutilized mesopelagic resources is among the possible solutions to increase capture fish production, which will also facilitate recovery of overexploited fish resources. Mesopelagics can be a source for fish meal, which is in great demand from the growing aquaculture and animal feed industry and will find applications in areas like nutraceutical and cosmetic industries. Recent estimates based on acoustic data, put the biomass of mesopelagic fishes between 11,000 and 15,000 million tonnes in the world oceans. Even though there is a large potential for developing a fishery for mesopelagics, very little information is available on the appropriate commercial harvesting systems. About 75% of total global catch of small mesopelagic fishes is accounted by myctophids. Average world annual production of myctophids between 1970 and 2015 has been 10,640 tonnes, with a maximum of 74,751 tonnes in 1990. Aimed midwater trawling and pair trawling with appropriate trawl designs have been considered suitable for harvesting meso-pelagic resources. An overview of the study is the mesopelagics in the Indian Ocean and its availability in the deep sea shrimp trawl bycatch. Sampling gears and commercial fishing techniques targeting mesopelagics are discussed along with details of experimental aimed midwater trawling conducted in Arabian Sea, targeting mesopelagic resources.

(2006) Report of the Committee of Experts on Ecological and Environmental Impact of Dredging at Vaduthala Kayal and Vaikam Kayal, Kerala. Submitted to The Government of Kerala, Thiruvananthapuram, 47 p.

Shell deposits in the proposed area lies roughly between 3m to 8m from the estuarine bottom. Overburden is about 3m to 6 m. Deep dredging operations required for mining the shell deposits will have impact on benthic community in the area of dredging. The impact of increased suspended solids, turbidity levels and nutrients is seen in near-field (< 1 km) from the dredging location which do not constitute an hazard. The impact of dredging is observed to be localized. The recovery of the benthic community is expected to take place within 1.5 to 3 years, after completion of the dredging activity. As regards heavy metals, impact of contaminated sediments was observed to be minimal, as no major industrial establishments have been historically operating in the dredging area. This is substantiated by the present observations in the Vaikam Kayal. Hydrographic studies at dredging site have revealed that turbidity, dissolved oxygen, pH, nutrients, heavy metals etc. do not shootup to a hazard level and in most cases the parameters are at normal level as for a dynamic estuary. In view of this, dredging could be permitted with a proper environment management plan. Good environmental management practices are recommended while pasturing on new areas: Formulation of an environment management plan and implementation of an environment monitoring plan. Base line status of the diversity and population of biota of economic significance in the proposed dredging site is to be determined. Monitoring of the area and immediate environs spanning about 1 km upstream and downstream may be arranged under the supervision of competent persons, during the pre-dredging, dredging and post-dredging periods if dredging operations continue for months. Livelihood alternatives may be provided for fishermen dependent on the dredged area and immediate environs, affected by dredging. The major impact is on the livelihood of persons and families (project affected persons - PAP) who are depending on the site for livelihood: fishing, clam harvest etc. The proponents have to identify PAPs and formulate a plan to rehabilitate them during the impact period. Affected stakeholders to be made beneficiaries for mussel culture, cage culture, ornamental fish culture, sea weed culture and freshwater and brackishwater fish culture; value addition to fish products, under Kerala government schemes. Measures for conservation of clam beds are given in the Report.

Abstract
Aspects of population dynamics of Spinycheek lanternfish Benthosema fibulatum (Gilbert and Cramer 1897), caught off the south-west coast of India were studied. The asymptotic length (L∞) and growth constant (K) were estimated at 108 mm and 0.460 yr-1 respectively while tmax was worked out as 6 years. Benthosema fibulatum grows faster initially and attains a total length of 101.22 mm over 6 years. The coefficients of total mortality (Z), instantaneous natural mortality (M) and fishing mortality (F) were estimated as 2.32 yr-1, 0.51 yr-1 and 1.81 yr-1 respectively. The exploitation rate (E) was estimated as 0.78 yr-1. Size at first capture (Lc) was estimated as 62.84 mm TL. The relative yield per recruit reached maximum at an exploitation rate (Emax) of 0.772. Though there has been no targeted fishery for myctophids in the area of study, they constituted a significant proportion of bycatch of deep sea shrimp trawlers. Benthosema fibulatum stock may be unsustainable when fishery intensifies in future to meet demand from fish meal industry, unless proper action is taken to manage the stocks.

As a source of food it contributes about 20 percent of animal protein supply. At present the total world capture fishery production is around 95 million tonnes. About 70 percent of the fish production is directly utilised for human consumption while the balance 30 percent is reduced fish meal and used in animal feed production. In this paper presented during UGC sponsored Seminar on Emerging Trends in Aquaculture, Harvesting and Post Harvesting Technology, 7-8 March 2012, Department of Zoology, Marthoma College, Tiruvalla, modern trends in Fishing Technology are briefly discussed.
