“…Atlantic mackerel (Scomber scrombrus) are extensively targeted by the pelagic purse seine fishing industry throughout Europe [35]. Considering that catch value for this species depends on quality [36,37], knowledge related to the determinants of flesh quality may facilitate economic benefits for an important industry. Although studies indicate that a wide variety of post-mortem storage and handling procedures can affect quality [38], there is currently a lack of knowledge related to the quality implications of capture stress in this species.…”

Physiological and flesh quality consequences of pre-mortem crowding stress in Atlantic mackerel (Scomber scombrus)

In commercial wild capture pelagic fisheries it is common practice to crowd catches to high densities to allow efficient pumping onboard. Crowding during the final stages of purse seine capture for small pelagic species often results in intense and sustained behavioural escape responses. Such a response may trigger a shift in energy production from aerobic to anaerobic pathways and result in metabolic acid accumulation and exhaustion of intracellular reserves of ATP. Where there is insufficient time or opportunity to recover to physiological equilibrium before death, pre-mortem stress may be an important determinant of fillet quality, as has been shown for a variety of farmed fish species. However, there is currently a lack of knowledge related to the flesh quality implications of capture stress for wild captured species in European waters. Here we show that crowding results in a physiological stress response that has consequences for flesh quality in the wild captured species Atlantic mackerel (Scomber scombrus). Using small schools in tanks and aquaculture net pens in three separate experiments, we found crowding results in physiological changes in mackerel consistent with an acute stress response and anaerobic metabolism. Consequently, we found crowded fish had more acidic pre-and post-mortem muscle pH as well as indications of faster onset and strength of rigor mortis and increased cathepsin B & L activity. We examined fillet flesh quality after two and seven days of ice storage and found reduced green colouration, increased gaping (separation of muscle myotomes) and reduced textural firmness associated with fish which had been crowded. However, the effects on quality were dependant on experiment and/or storage time. These results indicate the potential of crowding capture stress to influence the flesh quality of an economically important species and may have important implications for the wild capture pelagic fishing industry.

“…The most efficient purse seiners are the ones who use the shortest time to fill their quotas, as long as the product quality is not impaired, and thereby affect the market price obtained. The market prices are set in electronic auctions with no product inspections and conducted on a first-price, sealed-bid basis (Sogn-Grundvåg et al, 2019). Furthermore, a vessel is expected to have large catch capacity and modern capture and storage technology.…”

It is an established "truth" in the literature that a company which restricts itself to utilize existing resources without exploring new business opportunities is doomed to fail in the long run. An underlying premise for the claim is that the competition arena is dynamic and organized according to free competition principles. This study, however, examines whether it is more profitable for a fishing vessel to primarily exploit existing resources when the quota shares of the players are institutionally protected so that there is no real competition between them. The context is Norwegian seagoing purse seiners, which in 2005 experienced the introduction of a more market oriented individual transferable quota (ITQ) system with some distinct modifications. The vessels in the study were classified into strategic groups based on their exploitation versus exploration approaches. Financial accounts covering the period 2003-2017 were collected and analyzed to empirically address the issue. Some vessels did considerable explorative activities in the period studied by fishing related species, investing in quotas, and in new vessel technology. The findings suggest that firms which did not explore, but instead exploited their existing resource base performed relatively better than their peers except for EBITDA (earnings before interest, tax, depreciation and amortization) margin. Finally in the paper, the findings are discussed and implications outlined.

“…Another reason for using ecolabels is given by Roheim and Zhang (2018), who report that the ecolabel of the Marine Stewardship Council (MSC) reduces substitutability in Germany, making products with this label less exposed to competition. Finally, Sogn-Grundvåg et al (2019) argue that ecolabels may also reduce costs in the supply chain associated with new product development and marketing by extending product longevity. Their findings indicate that in the UK market, whitefish products with MSC and "line-caught" labels have a longer lifespan than products without these labels.…”

“…Farmed salmon is the most important seafood product consumed in the UK (Anderson, Asche, & Garlock, 2019;Asche et al, 2018), and differs from the whitefish studied by Sogn-Grundvåg, et al (2019) in several important aspects. Unlike wild fish on the European market, the "farmed" status is a prerequisite for consideration for any organic claim, but also precludes the use of the MSC ecolabel which applies exclusively to wild fish.…”

“…In contrast to wild fish, farmed salmon is mostly sold fresh, a highly perishable product form (Landazuri-Tveteraas, Asche, Gordon, & Tveterås, 2018). This makes coordination in the supply chain especially important (Kvaløy & Tveterås, 2008), and has led to the use of risk reducing instruments, such as contracts (Larsen & Asche, 2011) and futures (Asche, Misund, & Oglend, 2016), and avoiding auctions-a transaction mechanism that is much more common for wild fish (Sogn-Grundvåg, Zhang, & Iversen, 2019). On the other hand, the control over the production process allows salmon farmers to have product available year round, with minimal exposure to seasonality in production as is the case in wild fish production (Bertheussen & Dreyer, 2019;Birkenbach, Cojocaru, Asche, Guttormsen, & Smith, 2020).…”

In recent years, the number of ecolabels and country-of-origin labels has grown substantially in seafood markets globally. This makes it more difficult for retailers and producers to communicate and demonstrate their differentiating claims to consumers. In addition, it has recently been suggested that there are both costs and supply chain benefits associated with labeling. This paper uses duration analysis to investigate factors that influence product longevity for salmon in grocery retailing. Product longevity influences cost as a prolonged product lifetime reduces costs related to product development and marketing. As has been found for wild-caught whitefish, different retail chains appear to vary in their product labeling strategies. However, in contrast to wild fish, farmed salmon with ecolabels or domestic country-of-origin labels appear to have shorter product life cycles compared to products without ecolabels or with foreign country-of-origin labeling. This is most likely due to the higher control of the production process found in aquaculture.
