The present study investigated the effect of chitosan combined with lemon peel extract coating on the quality and shelf life of refrigerated yellowfin tuna meat using physicochemical, microbial and sensory assessments. Fresh yellowfin tuna meat as chunks were divided into five lots and coated with lemon peel extract (LPE) and chitosan (CH) at different concentrations viz., control, C (0%), LPE 1%, CH 1%, LPE+CH 1% and LPE+CH 2% (w/v). Sensory, biochemical and microbial quality of the samples were observed for 12 days during 4°C refrigerated storage. Sensory evaluation revealed that shelf life of yellowfin tuna under the study was 6 days for control, 8 days each for LPE (1%) and CH (1%), 10 and 12 days for LPE+CH (1%) and LPE+CH (2%) respectively. Significantly higher pH, total volatile basic nitrogen (TVB-N), tri-methyl amino nitrogen (TMA-N), peroxide value (PV) and thiobarbituric acid reactive substances (TBARS) values were recorded in control samples than coated samples (p<0.05). Significant reduction in microbial counts were recorded in CH+LPE treated samples (p<0.05) compared to the LPE or CH coating alone, in the later stages of storage. Coated samples with combination of LPE+CH 1% and 2% indicated better storage qualities compared to other treatments. The present study revealed that LPE along with chitosan edible coating enhanced the shelf life of yellowfin tuna meat.

Decline quality of Tuna as a result of abuse temperature and long shelf life time. Histamine, microbial and sensory odours become one of the global problems that can cause health problems. Large number of bacteria dominated in viscera area rather than other fish parts. This study was conducted to determine the effect of storage temperature on histamine, microbial and sensory odours on middle of Yellowfin Tuna. This study used descriptive explorative method, sampel were periodically taken for analyses at intervals 48 hours (0ºC), 8 hours (10ºC) and 4 hours (25ºC). Yellowfin Tuna was rejected earlier by the sensory odours than TPC and histamine. During storage at 0ºC for 720 hours histamine levels still acceptable for consumption however TPC already exceeded the limit after 672 hours and rejected by sensory odours for 624 hours storage. During storage at temperature 10ºC did not reached the limit for 120 hours while TPC value already reached 2x106 cfu/g for 88 hours storage and rejected by sensory odours for 72 hours storage. During storage at temperature 25ºC histamine reached 67.3 ppm for 32 hours, ALT reached 5.5x105 cfu/g for 24 hours and rejected by sensory odour for 20 hours of storage. Histamine formation correlates with the growth of microbial counts and decrease of sensory odours value. Suhu yang tinggi dalam waktu simpan lama berpengaruh terhadap penurunan kualitas ikan tuna. Histamin, mikroba dan bau busuk menjadi salah satu permasalahan global yang dapat menyebabkan masalah kesehatan. Bagian tengah ikan menjadi sumber bakteri paling tinggi dibandingkan bagian lainnya. Penelitian ini bertujuan untuk mengkaji perkembangan histamin, ALT dan sensori bau pada bagian tengah Tuna sirip kuning dalam penyimpanan suhu yang berbeda. Penelitian ini menggunakan metode deskriptif eksploratif, sample di analisis secara berkala pada suhu 0ºC (48 jam), 10ºC (8 jam) dan 25ºC (4 jam). Tuna sirip kuning mengalami pembusukan lebih awal berdasarkan parameter sensori bau, kemudian disusul ALT dan Histamin. Kandungan histamine pada suhu 0ºC masih layak untuk dikonsumsi setelah 720 jam, namun nilai ALT melebihi batas aman setelah 672 jam penyimpanan dan nilai sensori bau setelah 624 jam penyimpanan. Penyimpanan suhu 10ºC tidak menyebabkan peningkatan histamin melebihi batas limit setelah penyimpanan selama 120 jam, sedangkan nilai ALT mencapai 2x106 cfu/g setelah 88 jam dan nilai sensori bau menyatakan ikan busuk setelah penyimpanan selama 72 jam. Penyimpanan suhu 25ºC histamin mencapai 67,3 ppm setelah penyimpanan 32 jam dan nilai ALT 5,5x105 cfu/g pada penyimpanan ke 24 jam serta ikan dinyatakan busuk berdasarkan sensori bau setelah 20 jam penyimpanan. Peningkatan histamin berkorelasi dengan pertumbuhan jumlah mikroba dan penurunan nilai sensori bau.

Yellowfin tuna (Thunnus albacares) and bigeye tuna (T. obesus) were tagged and released in the north-western Coral Sea off northern Queensland in 1991 and 1992. Over the next five years, recaptures were reported by Australian longline vessels based in Cairns and fishing in the release area, and by industrial tuna fleets fishing in the adjacent western Pacific region, thus demonstrating clear links between the tuna stocks in these areas. Some southerly movements of yellowfin, in particular, further suggested links with stocks supporting the longline fishery in the south-eastern Australian Fishing Zone. Bigeye tuna tag returns and catch per unit effort by Cairns-based longliners showed a strong seasonal signal, peaking in mid year. Yellowfin tag-return data displayed a similar, but weaker, seasonal pattern. The data were analysed by use of tag-attrition models with seasonally variable catchability and with two assumptions regarding changes in targeting of the two species by longliners during the study. Under both assumptions, the local exploitation rates for yellowfin are low: about 0.07 in 1996. For bigeye, the local exploitation rate in 1996 may have been as high as 0.30, warranting a cautious approach to further fishery expansion in this area.
