“…The relatively low lipid concentrations in white muscle (<5% of wet mass) have been observed previously (Medina et al ., ; Saito et al ., ; Bodin et al ., ; Sardenne et al ., , ). Thus, K. pelamis can be defined as a lean fish.…”

The lipid composition of somatic and reproductive tissues was determined for female skipjack tuna Katsuwonus pelamis caught in the western Indian Ocean between latitude 10° N and 20° S and longitude 40° and 70° E. The highest total lipid (TL) contents were in the liver and gonads, with white muscle levels approximately three-fold lower. Three lipid classes dominated: triacylglycerols (TAG), sterol esters and wax esters (SE-WE) and phospholipids (PL). Collectively, these accounted for between 70 and 80% of TLs. Changes in lipid concentrations were evaluated over the maturation cycle. Immature fish had the lowest gonad and liver TL levels; concentrations of TL, TAG, SE-WE and PL accumulated from immature to mature (spawning-capable) phase, reflecting sustained vitellogenic activity of the liver and a transfer of lipids to developing oocytes from the onset of vitellogenesis. Gonado-somatic and hepato-somatic indices were positively correlated with each other and positively related to TL in the gonads and liver. Fulton's condition index and lipid concentrations in muscle did not vary significantly over the maturation cycle; fat content in the main storage tissues was undepleted as the ovary developed. Hence, K. pelamis apparently supports reproduction directly from food intake over the breeding season. In the gonads, reserve lipids (SE-WE and TAG) and sterols were related to batch fecundity but this was not the case for somatic and hepatic tissues. These results suggest that K. pelamis utilizes an income breeding strategy.

“…From the moment they are caught till they are ready to be canned, marine species are submitted to varied handling and technological stages (Horner, 1997;Aubourg, 2001). Among them, brine immersion freezing (BIF) has widely been employed on-board after capture by large fishing vessels and by tuna canneries; in it, immersion in an aqueous solution with a low freezing point would lead to a fast freezing of fish pieces, thus allowing the storage of huge quantities of raw material (Aubourg & Gallardo, 2005;Bodin et al, 2014). To preserve the quality of marine species to be further employed for canning, different strategies are employed.…”

“…To preserve the quality of marine species to be further employed for canning, different strategies are employed. In spite of these advantages, the application of the method may undergo temperature variations and negative effects during handling; as a result, physical, chemical and microbiological changes may occur, these leading to microbial activity and lipid oxidation development (Aubourg & Ugliano, 2002;Bodin et al, 2014). The preservative effect of salt has been attributed to less availability to microbial attack, enhancement of functional properties and decrease in water activity (Chiralt et al, 2001).…”

Summary The present research focused on the biogenic amines (BAs) formation in skipjack tuna (Katsuwonus pelamis) throughout the whole canning process. In agreement with its wide employment on this species, on‐board brine immersion freezing (BIF) was tested as post‐mortem processing. The study included fish samples corresponding to different stages of the canning process such as frozen, thawed, cooked and canned; after cooking, two kinds of tuna muscles were considered, that is, whole fillets (main product) and grated muscle (off‐product arising from small pieces). For the BAs (tryptamine, putrescine, cadaverine, histamine, spermidine and spermine) assessment, an HPLC‐DAD method was developed and validated in skipjack tuna samples, in agreement with different parameters such as suitability, linearity, limits of detection and quantification, precision, accuracy and robustness. Tuna submitted on‐board to BIF procedure provided low levels of spermine and spermidine (up to 27.6 mg kg−1), while contents on the remaining BAs maintained below the limit of detection. Throughout the different stages of the canning process, skipjack tuna showed a low formation of most BAs; interestingly, histamine content was found below 10.6 mg kg−1 level. The highest values were obtained for spermidine, these related to cooked grated tuna (from 22.6 to 66.7 mg kg−1) and canned grated tuna (from 70.6 to 104.4 mg kg−1). Values for pH assessment in all kinds of tuna samples corroborated the results obtained for BAs determination. BIF procedure proved to be an amenable post‐mortem processing to guarantee the quality of canned skipjack tuna.

Models using published estimates for parameters from other species cannot be used. Based on a range of lipid content that do not exceed 45%, we recommend the linear model to correct the bulk δ(13)C values in the investigated tissues but the parameters have to be estimated from a proportion of the original data for which chemical extraction is required and the isotopic values of bulk and lipid-free tissues are measured.
