Longtail Tuna

Longtail tuna (Thunnus tonggol, Bleeker, 1851), the largest growing species among neritic tunas have a unique distribution pattern globally. Northern Arabian Sea together with the Oman Sea and Persian Gulf in the north-western Indian Ocean is considered to be the major area where the species is abundant and form sizeable fisheries globally. India has an artisanal tuna fishery and contributes nearly 10% of the longtail tuna landing in the region, with Gujarat alone contributing nearly 80%. The paper updates on the longtail tuna fisheries in the region with focus on the north-west coast of India together with its spatial characteristics. Clues on the areas of abundance of the species along Gujarat coast over the seasons and temporal movements of different ontogenetic stages in the shelf areas are revealed. The study sets prelude to a cost effective and participatory collection of spatially referred data on the artisanal and small scale fisheries in the region.

The length at first maturity of cobia Rachycentron canadum (Linnaeus, 1766) was estimated from 292 specimens collected during exploratory surveys along the north-west coast of India and from fish landing centres in Mumbai, Maharashtra. Length and age at first maturity of male and female were estimated as 63 and 70 cm and 1.5 and 1.75 years respectively.

Dol net is traditionally used for fishing along the north-west coast of India. In this study, the operational as well as economic aspects of dol net operation off Navabandar, Gujarat was studied. Dol nets operations from mechanised boats locally called as Van along Navabandar coast were considered for the present study. The overall length (OAL) of the mechanised vessels were in the range, 10-12.8 m with 2.4-3.6 m breadth and 1-1.8 m height. The total capacity of vessels was in the range 15-20 t and average fish holding capacity was 2.5 t. The fishing vessels had six cylinder engines of 87 to 105 hp. Fishermen themselves fabricated the nets for the dol net, which had seven different parts with various lengths. Kaba-sus system using steel pipes was the method of dol net fishing off Navabandar. They were locally known as Bochi, Patiya, Aor, Trijo, Bangu, Chothi and Jalo. The study indicated that the profit of a dolnetter at Navabandar in a year was `2,88,122.

This paper uses customs figures to show that herring exports from the east and west coast lowlands expanded significantly in the last six decades of the sixteenth century. The paper argues that the rise was primarily due to the north-west Highland fisheries being opened up and exploited by east and west coast burghs. These ventures required greater capital supplies and more complex organisation than their local inshore fisheries and they were often interrupted by political hostilities. However, the costs were a fraction of those required to establish a deepwater buss fleet, enabling Scotland to expand production and take advantage of European demand for fish while minimising additional capital costs.

AbstractThe city of Essaouira is located along the north-west coast of Morocco, where groundwater is the main source of drinking, domestic and agricultural water. In recent decades, the salinity of groundwater has increased, which is why geochemical techniques and environmental isotopes have been used to determine the main sources of groundwater recharge and salinization. The hydrochemical study shows that for the years 1995, 2007, 2016 and 2019, the chemical composition of groundwater in the study area consists of HCO3–Ca–Mg, Cl–Ca–Mg, SO4–Ca and Cl–Na chemical facies. The results show that from 1995 to 2019, electrical conductivity increased and that could be explained by a decrease in annual rainfall in relation to climate change and water–rock interaction processes. Geochemical and environmental isotope data show that the main geochemical mechanisms controlling the hydrochemical evolution of groundwater in the Cenomanian–Turonian aquifer are the water–rock interaction and the cation exchange process. The diagram of δ2H = 8 * δ18O + 10 shows that the isotopic contents are close or above to the Global Meteoric Water Line, which suggests that the aquifer is recharged by precipitation of Atlantic origin. In conclusion, groundwater withdrawal should be well controlled to prevent groundwater salinization and further intrusion of seawater due to the lack of annual groundwater recharge in the Essaouira region.
