Across the Global South, commercial development and technological innovations are transforming fish food systems in ways that significantly impact the livelihoods of small-scale producers and the food security of the poor. A crucial but understudied aspect of such transformations is the social relations in which fish food systems are embedded. Food system transformations change power relations and rework gendered economic roles and divisions of labour in ways that often marginalise women and other vulnerable groups. In this paper, we draw on feminist studies of gender and technology and feminist commodity chain analysis to investigate the impact of technological transformation on social relations in the ring seine fishery of Kerala, India. Kerala’s ring seine fishery specifically targets small pelagics like sardine, mackerel, and anchovies, which have been identified as important to the food security and nutrition of the poor. Since the mid-1980s, when the ring seine was first introduced to enable small-scale fishers to compete with mechanised trawlers, these fishing units have expanded both in terms of numbers and in size, largely as a result of locally-driven technological innovation and adaptation. Though traditional arrangements of labour deployment and wage sharing have remained, rising competition and differentiation between fishermen have ensued. At the same time, changes in processing, distribution, and trade have reworked women’s economic roles and position in the fishery, and questions about long-term profitability and sustainability have necessitated interventions in governance at various levels. Tracing the trajectory of technological innovation and changing social relations through the value chain, we assessed the gendered implications of fish food system transformations for livelihoods. We found that the increase in dimensions of the new gear increased both investments and operational costs of the fishing units rendering several of them uneconomical. Time-tested social norms have also changed as competition increased, which is much more pronounced between the smaller and larger fishing vessels. The traditional wage sharing pattern still remains ensuring income security for fishermen who cannot find work as crew on these fishing vessels. Women, however, have been most affected by the changes as they no longer are able to access the fish resource as earlier for engaging in post-harvest activities, such as marketing and fish drying.

The seasonal and sex-wise variations in fatty acid and mineral composition in the tissue of Odonus niger collected from the Karnataka coast, southeastern Arabian Sea, were evaluated for the first time. The fatty acid profile was assessed using gas chromatography, nutritional indices were employed to evaluate lipid quality, and standard methods were utilized to estimate mineral composition and heavy metals. Palmitic acid (20.2–45.9%), oleic acid (10.0–19.2%), and docosahexaenoic acid (10.9–36.7%) were found in the highest proportions. The amount of ω3 fatty acids was significantly higher than ω6 fatty acids indicating the healthiest food fish and a promising source for nutrient supplementation. The P/S (PUFA/SFA) and ω3/ω6 ratios of the species were greater than those recommended by the UK Dept. of Health. Index of atherogenicity (IA) and thrombogenicity (IT) was low, and hypocholesterolemic to the hypercholesterolemic ratio (HH), unsaturation index (UI), health-promoting index (HPI), fish lipid quality (FLQ), and polyene index (PI) were high. The relationship between the quantities of macronutrients and trace elements was calculated as K > P > Na > Mg > Ca and B > Fe > Zn > Ga > Al respectively. Heavy metals like Be, Bi, Co, and Hg were found below the detection level. Benefit-risk ratio value indicates that the species is safe for consumption.

The performance of the starter culture is a critical factor that decides the quality of fermented milk. Dahi is a fermented milk product popular in India made using a mixed starter culture of lactic acid bacteria comprising acid and flavour producers. The prevalence of bacteriophages in the dairy environment can critically affect the activity of these starter cultures resulting in starter failure. As there is little information available on the occurrence of bacteriophages in the dairy environment of Kerala, this research communication examines the presence of lytic bacteriophages acting against three potential flavour-producing strains of Lacticaseibacillus paracasei (Lc. paracasei). Dairy effluent samples were screened for the presence of phages against the strains of Lc. paracasei by the multiple host enrichment method. Plates showing clearance zone in spot assay were confirmed for the presence of phages by double-layer agar assay. The plaques obtained in the double-layer agar assay were purified for further identification by next-generation sequencing. A bacteriophage infecting one of the three strains of Lc. paracasei was detected by the plaque assay and the blast annotation of the bacteriophage sequence found 86.05% similarity of the phage to Siphoviridae family. The study endorses the need for monitoring phages in the dairy environment to control phage-related starter failure in the state of Kerala.
