Impact of the Covering Vegetable Oil on the Sensory Profile of Canned Tuna of Katsuwonus pelamis Species and Tuna’s Taste Evaluation Using an Electronic Tongue

The impact of the covering vegetable oil (sunflower oil, refined olive oil and extra virgin olive oil, EVOO) on the physicochemical and sensory profiles of canned tuna (Katsuwonus pelamis species) was evaluated, using analytical techniques and a sensory panel. The results showed that canned tuna covered with EVOO possesses a higher content of total phenols and an enhanced antioxidant capacity. This covering medium also increased the appreciated redness-yellowness color of the canned tuna, which showed a higher chromatic and intense color. Olfactory and kinesthetic sensations were significantly dependent on the type of oil used as covering medium. Tuna succulence and adhesiveness were promoted by the use of EVOO, which also contributed to decreasing the tuna-related aroma sensations. The tuna sensory data could be successfully used to identify the type of vegetable oil used. Moreover, a potentiometric electronic tongue allowed discriminating between the canned tuna samples according to the vegetable oil used (mean sensitivity of 96 ± 8%; repeated K-fold cross-validation) and the fruity intensity of the EVOO (mean sensitivity of 100%; repeated K-fold cross-validation). Thus, the taste sensor device could be a practical tool to verify the authenticity of the declared covering medium in canned tuna and to perceive the differences in consumers’ taste.

A Bayesian Multilevel Ordinal Regression Model for Fish Maturity Data: Difference in Maturity Ogives of Skipjack Tuna (Katsuwonus pelamis) Between Schools in the Western and Central Pacific Ocean

The maturity ogive is vital to defining the fraction of a population capable of reproduction. In this study, we proposed a novel approach, a Bayesian multilevel ordinal regression (i.e., Bayesian continuation ratio model), to model the maturity ogive. The model assumes that the observed maturity stage originates from the categorization of latent continuous variables. We demonstrated this approach by testing whether there are differences in the maturity ogive of skipjack tuna (Katsuonus pelamis) in the western and central Pacific Ocean between two school types, i.e., free-swimming and floating-object-associated schools. The model results show that K. pelamis, given the same fork length, are more likely to have a higher maturity stage in a free-swimming school than those associated with floating objects. The gonadosomatic index revealed the same conclusion. Our results indicate that fish aggregation devices (FADs) could negatively affect the maturity of K. pelamis and consequently reduce the population reproductive potential. This study provides (1) an alternative approach to analyze fisheries ordinal data; (2) important quantitative evidence to evaluate the existing ecological hypotheses; and (3) implications for tuna fisheries management.

Research of parasites with zoonotic potential for humans in skipjack tuna (Katsuwonus pelamis)

The skipjack tuna (Katsuwonus pelamis) is commonly found in the tropical waters of the oceans. It is a fishing resource of high economic value and available for national and international markets. Therefore, it is important to know the fish parasites for a correct sanitary inspection, as the pathogenesis in humans can occur through spoliative, toxic or mechanical action. This study aimed to identify the zoonotic parasitic fauna that infects the beautiful-striped using morphological methods. A total of 06 samples were analyzed. The fish were necropsied for parasitological evaluation of the musculature and internal organs. The samples were visually inspected and the structures with morphology combining with parasitic shapes were analyzed both in stereoscopic and microscope. The parasites found were fixed in 70% alcohol for later identification. All samples showed the presence of zoonotic parasites for humans. Two genera of zoonotic parasites have been found for humans that have beautiful tuna as their hosts, namely Anisakis sp. (Nematoda) and Trypanorhyncha (Eucestoda). A 100% of the infections occurred in the muscles and 66.6% in the liver. The results reinforced the importance of inspection by responsible organisms on the importance of evisceration as quickly as possible to avoid migration of larvae to the muscle.

Effects of preservation on chemical composition and sensory analysis of skipjack tuna (Katsuwonus pelamis) in Tema, Ghana

Although fish is an integral part of Ghanaian diets and play important nutritional role, much research has not been conducted with respect to the nutritional composition and sensory analysis of marine fishes in Ghana. This study evaluated chemical composition and sensory analysis of Skipjack tuna (Katsuwonus pelamis) sampled from Tema in the Greater Accra region of Ghana. Four different samples; very dry smoked (Sample A), dry smoked (sample B), moist smoked (sample C) and fresh (sample D) skipjack tuna were used for this study. Chemical composition (moisture, ash and protein) was analysed using standard laboratory methods whilst sensory parameters (colour, odour, flavour, texture and overall acceptance) were assessed using 20 trained panelists. There were significant differences in moisture and crude protein contents (P < 0.05). Ash content was however non-significantly different. Moisture content for very dry smoked skipjack tuna, dry smoked skipjack tuna, moist smoked skipjack tuna and fresh skipjack tuna were 49.79 ± 1.73 %, 60.22 ± 1.80 %, 59.32 ± 0.01 % and 68.65 ± 0.16 %, respectively whilst crude protein content were 90.83 ± 1.09 %, 73.32 ± 1.09 %, 88.15 ± 1.19 % and 91.72 ± 0.19 %, respectively for very dry smoked skipjack tuna, dry smoked skipjack tuna, moist smoked skipjack tuna and fresh skipjack tuna. It can be concluded that different methods of preservation (smoking) have significant influence on proximate composition as well as sensory analysis. It is suggested that further studies be conducted on sensory analysis and proximate composition of fish sold on Ghanaian markets. In addition, we recommend that the Food and Drugs Authority (FDA) conduct regular studies on fish to ascertain the quality.

Comparison of handline tuna catches in Indian Ocean and Banda Sea waters

There are two essential landing sites for handline tuna in Indonesia: Palabuhanratu (in the Indian Ocean) and Kendari (in the Banda Sea). This paper analyzes handline catches from the Indian Ocean and Banda Sea waters as the main fishing ground. The catch composition of the handline tuna landed in Kendari is more varied than Palabuhanratu. Several species commonly caught are yellowfin tuna (Thunnus albacares), skipjack tuna (Katsuwonus pelamis), bigeye tuna (Thunnus obesus) as a target species, and some billfish species as bycatch. Mean CPUE for handline tuna landed in Palabuhanratu is lower than Kendari. A significant difference is based on the monthly mean CPUE variation between Palabuhanratu and Kendari landing sites (p < 0.001). Handline catches in Palabuhanratu had a more comprehensive range of length sizes than Kendari, using a two-sample K-S test showed significant differences (p < 0.001). The fish size landed in Kendari is relatively smaller than Palabuhanratu. The average length of fish caught by handline is smaller than the length at first maturity (Lm) value in both landing sites. The use of large size hook for hand lines is recommended for catching tunas in this area.

Region Proposal and Regression Network for Fishing Spots Detection From Sea Environment

In this paper, a two-stage method is proposed for predicting the catch of skipjack tuna ( Katsuwonus pelamis ) from a 2D sea environmental pattern. Following the assumption that sea water temperature and sea surface height (SSH) which fishermen often use for finding fishing spots has a correlation with the skipjack tuna catch, a new approach of using Faster R-CNN in object detection is proposed. The proposed method consists of two part. In the first part, taking a sea temperature map as input, Faster R-CNN extracts the candidates of where skipjack tuna would be on the map in order to imitate the behaviors of fishers. In the second part, Support Vector Regression (SVR) estimates the catch amount in each candidate. Fater R-CNN is applied to several sea environmental patterns with three different loss functions and compares each performance. The proposed model is evaluated by comparing the result with average fishers’ ability on the skipjack tuna catches and several criteria for evaluating the proposed model. The results show that the proposed method is able to outperform the average fishers’ ability by an average of 3%.

Source-dependent compositional changes in coconut flavoured liquid smoke and its application in traditional Indian smoked fishery products

ABSTRACT Smoking is an age-old food preservation method. Intense smoking results in deposition of carcinogenic polycyclic aromatic hydrocarbons (PAH) in food. Replacing traditional smoking practices with application of liquid smoke or smoke flavouring is proven to reduce the PAH content without adversely affecting flavour of the products. This study explores source-dependant variations in composition of a coconut-flavoured liquid smoke. Liquid smoke produced from coconut husk (CH), coconut fibre (CF) and coconut fibre powder (CP) was analysed for total phenolic content, total carbonyls, titratable acidity, pH and PAH content. Resultant liquid smokes were also compared a commercial liquid smoke (CL) for composition. Total phenolic content in the liquid smokes ranged from 1518 ± 184 (CH), 1037 ± 110 (CF), 834 ± 48.23(CP) and 20047 ± 193 mg L−1 (CL). Commercial liquid smoke showed highest total PAH content 215 ± 15.45 ng ml−1 followed by 8.23 ± 1.47 (CP), 7.22 ± 1.44 (CF) and 0.64 ± 0.13 ng m−1 (CH). Further, process parameters for producing ‘masmin’ – a popular traditional smoked and dried ready-to-eat product – by replacing traditional smoking practices with liquid smoking were standardised using Response Surface Methodology. Spraying cooked skipjack tuna (Katsuwonus pelamis) loins with coconut husk liquid smoke containing 4% salt for 155 min at flow rate of 3 L hr−1 and chamber temperature of 60°C was found to give the product a matching flavour with traditional masmin.

Potential predictability of skipjack tuna (Katsuwonus pelamis) catches in the Western Central Pacific

The Pacific Island countries have a substantial socio-economic dependency on fisheries. Skipjack tuna is one of the most important species in the Western Central Pacific (WCP) and its catches in this region exhibit a spatio-temporal variability influenced by ocean conditions, mainly the El Niño-Southern Oscillation (ENSO). This study investigates the relationship between skipjack tuna catch amounts and environmental variables in the equatorial Pacific during 1990–2014, and evaluates the potential predictability of the catches based on their statistical relationship. A series of regressed and reconstructed spatial patterns of upper-ocean temperature, salinity, currents and precipitation represent ENSO-like variability, and their principal component time series are used to estimate the predictability of skipjack tuna catches in the Federated States of Micronesia (FSM). ENSO-like variability depicted from 100 m temperature and 5 m salinity in the equatorial Pacific exhibit a significant predictability for the annual catch amount in the FSM for several years with a training period of > 20 years. This suggests that the subsurface temperature or near surface salinity can be a better predictor of ecosystem variability than widely used sea surface temperature. Applications of this result to other species could have broad implications for the fishery industry in the WCP.

Vulnerability of Baitfishes of Handline and Lift Net Fishing Gear that Landed in Kendari, Bitung, Wakatobi and Larantuka Fishing Port

The high intensity of catching has an impact on decreasing stock, vulnerability, which has the potential affect to stock sustainability; such vulnerabilities include the baitfishs group in tuna fisheries. Vulnerability studies of baitfishs in Bitung, Wakatobi, Kendari and Larantuka in July 2013 were carried out to find out the pressure caused. The data collected is the parameter of productivity and perception of fish. The catches besides tuna are skipjack tuna (Katsuwonus pelamis), Indian Scad (Decapterus russelli), little tuna (Euthynuss affinis), Squid (Loligo loligo.), Anchovies (Stelophorus commersonii) and Sardinella (Sardinella fimbriata). Based on MSC (Marine Steward Council) Vulnerability Criteria, vulnerability index in Bitung (skipjack = 85.6; scad = 98.9; little tuna = 96.2), Wakatobi (scad = 97.9; squid = 98.5) and Kendari (skipjack= 85.6; anchovies = 98.5) and Sardinella fimbriata is about 96 in Larantuka. The conclusion of this research are the baitfishes state as low vulnerability and low risk and potential for sustainability

Growth Pattern of Skipjack Tuna (Katsuwonus Pelamis) Landed in PPI Kedonganan Bali

Skipjack Tuna (Katsuwonus Pelamis) is one of the big pelagic fish in fishery resources that has high economic value and plays an important role in export activity in Indonesia. Catch activities for consumption needs for people could threatened of Skipjack Tuna availability. The growth pattern of Skipjack Tuna is needed to used as references for the appropriate management plan to protect Skipjack Tuna. The research was conducted from February to April 2017 at PPI Kedonganan, Kuta District, Badung, Bali. The fish were collected by simple random sampling method. This study showed that gillnet and handline were used as fishing gears. The length frequency distributions were in the long-range of 315-337 mm means the catch fish is still young. The growth pattern of Skipjack Tuna was negative allometric means length growth was faster than weight growth. The growth parameters of Skipjack Tuna were obtained by the asymptotic length (Linf) of 875.2 mm, growth coefficient (K) of 0.09, and theoretical age (t0) of -0.78. Skipjack Tuna have small body size with condition factors were ranged from 0.8783-1.7269. It can be concluded that these methods can be used to determine the appropriate management efforts.

Developing an Abundance Index of Skipjack Tuna (Katsuwonus pelamis) from a Coastal Drifting Gillnet Fishery in the Southern Waters of Indonesia

Skipjack tuna is targeted by various types of fishing gear in coastal countries. Due to itsresilience, it has withstood heavy fishing pressure in the past few decades. Coastal drifting gillnetfleets also mark skipjack as their main target, but it is often overlooked in terms of stock assessment.This study provides new information on an abundance index based on fishery-dependent data from2010 to 2017. Generalized linear models (GLMs) were used to standardize the catch-per-unit-ofeffort(CPUE) using year, quarter, and gross tonnage as the prediction variables. Model goodnessof-fit and model selection were based on the Akaike Information Criterion (AIC), the pseudocoefficient of determination (R2), and model diagnostics with a residual analysis. The finalestimation of the abundance index was calculated by least square means or marginal means. Theresults showed that the index was heavily influenced by the year and quarter, but it did not relateto the vessel’s capacity. While the CPUE series fluctuated greatly, it showed a declining trend overthe years of observation.

Growth variability of juvenile skipjack tuna (Katsuwonus pelamis) in the western and central Pacific Ocean

We examined growth rates of juvenile skipjack tuna using otolith daily increment analysis to clarify geographic differences in early-life stage growth in the western and central Pacific Ocean (WCPO). We used a liner regression model to analyze the relationship between standard length (SL) and age (in days). The slope of growth model was significant difference between regions. There were rapid increases in the otolith mean daily increment width of juveniles at 7 days after hatching (DAH) and 10 DAH in the Western Pacific Warm Pool (WARM) and North Pacific Tropical Gyre area (NPTG), respectively. These periods correspond to the timing at which larvae complete their digestive-system development and start the piscivory. We found significant difference in logarithmic back-calculated SL between WARM and NPTG at 3 DAH (p < 0.01). Mean growth rates until 10 DAH, when the larvae metamorphose into juveniles, were positively correlated with sea surface temperature (r = 0.52). These results indicate that geographic difference in the growth of juvenile skipjack tuna caught in the WCPO in boreal winter cause in the larval stage, and that these differences are related to sea surface temperature.

Antihypertension Effect from Bakasang’s Peptide Extract Based on MDA Levels in Sera and iNOS Expression in Cardiac Tissue of Rats Hypertensive Model

Hypertension is an abnormality of cardiovascular condition, marked by high-blood pressure over normal condition. One of the factors that causes hypertension is altered equilibrium of Renin-Angiotensin-Aldosteron system, which commonly caused by genetic disorder, could produces excess of Angiotensin II which known as vasoconstrictor. Angiotensin II elevates body’s blood pressure and stimulates production of free radicals causes hypertension and oxidative stress. This research conducted to explore potential antihypertension effect from bakasang’s peptide extract made from fermented skipjack tuna (Katsuwonus pelamis L.) based on MDA levels in sera and iNOS expression in cardiac tissue from hypertension rats (Rattus norvegicus) induced by DOCA-salt. Rats were divided into five groups, they were: (1) negative control group, (2) hypertensive control group, (3) hypertension with captopril therapy with dose of 5 mg/kg of body weight (BW), (4,5) bakasang’s peptide extract therapy with dose of 200 mg/kgBW, and 300 mg/kgBW respectively. The results showed that bakasang’s peptide extract with dose of 200 mg/kgBW significantly decrease (p less than 0.05) MDA level in sera and iNOS expression in cardiac tissue. MDA level decreased up to 32.77%, and iNOS level of expression decreased up to 34.46 % after therapy using bakasang’s peptide extract on hypertension rats. It can be concluded that bakasang’s peptide extract has antihypertension effect (ACE-inhibitor), and capable to decrease MDA levels in sera and iNOS expression in cardiac tissue on hypertension rats induced by DOCA-salt.

The Antihypertension Effect of Fermented Skipjack Tuna (Katsuwonus pelamis L.)/Bakasang’s Peptide Extract Based on Cardiac’s Histopathology and Protease Activity on Hypertensive Rats Induced by Deoxycorticosterone Acetate (DOCA) -Salt

Hypertension is an abnormality of cardiovascular condition, marked by high-blood pressure over the normal condition. One of the factors that causes hypertension is altered equilibrium of Renin-Angiotensin-Aldosteron system (RAAS). This condition, which commonly by genetic could causes excess production of Angiotensin II, which known as vasoconstrictor, carried out by Angiotensin Converting Enzyme (ACE). Angiotensin II could increases the body’s blood pressure, and stimulates the production of free radicals, causing hypertension and oxidative stress. One of the common medication for hypertensive patient are using ACE inhibitor pills. Consumption of commercial pills, had a negative effect on the patient, such as skin iritation, cough, allergic reaction, etc. This study was conducted to explore the potential peptide of bakasang extract isolated from fermented skipjack tuna (Katsuwonus pelamis L.) for antihypertensive therapy, based on the activity of protease and histopathology of cardiac tissue on hypertensive rats (Rattus norvegicus) induced by DOCA-salt. The rats were divided into five groups: (1) negative control group, (2) hypertensive control group, (3) hypertension with captopril therapy dose of 5 mg/kg of body weight (BW), (4) and (5) hypertension with bakasang’s peptide extract therapy dose of 200 mg/kgBW, and 300 mg/kgBW, respectively. The results showed that bakasang’s peptide extract dose of 200 mg/kgBW significantly (p less than 0.05) decrease protease activity and improve histopathology of cardiac tissue on hypertensive rats. Protease activity post-therapy decreased to be 39.27 % from positive hypertension group. It could be concluded that the peptide of bakasang’s peptide extract has antihypertension effect (ACE-inhibitors), which was able to improve histopathology and decrease protease activity of the cardiac tissue on hypertensive rats induced by DOCA-salt.

Nutritional attributes in the fillet of skipjack tuna (Katsuwonus pelamis) from the Arabian Sea near the south-west coast of India

Inter-annual and seasonal variability in the nutritional parameters of the edible portion of skipjack tuna (Katsuwonus pelamis) collected from the Arabian Sea were determined for a period of 4 years. Greater levels of long chainn-3 fatty acids (35% during pre-monsoon), critical in the human diet for their anti-inflammatory properties with greatern-3:n-6 fatty acid ratio (8:12) demonstrated that this species may serve as an alternative to balance the greater amount ofn-6 fatty acids. The present study demonstrated skipjack tuna as a significant source of protein, amino acids, minerals and vitamins. A balanced essential to non-essential amino acid ratio (1.2:1.4) in the fillets indicated that this species could provide well-balanced protein depositions. Vitamins A and K1demonstrated post-monsoon maxima, whilst vitamins D3and E showed pre-monsoon maxima. Greater calcium (172 mg 100 g−1) and phosphorus contents (923 mg 100 g−1) were recorded in the fillets of skipjack tuna during the pre-monsoon season. The chlorophyll-a concentration and sea surface temperature of its habitat were considered to understand their effect on the nutritional composition of skipjack tuna all through the study period. Significant correlation between long chainn-3 polyunsaturated fatty acids such as eicosapentaenoic acid and docosahexaenoic acid (r2~ 0.99) of skipjack tuna alongside chlorophyll-a concentration was observed, particularly during the monsoon. The lesser atherogenic/thrombogenicity indices (&lt;1), greater hypocholesterolaemic/hypercholesterolaemic ratio (&gt;1.0), and lesser cholesterol contents (&lt;50 mg 100 g−1) of the fillets in skipjack tuna contributed towards its parameters to be qualified as a high value, balanced nutritional source.
