Fish protein concentrate (FPC) is a healthy and highly nutritive product produced hygienically from fishes in which, protein and other nutrients are more concentrated than fresh fishes. In the present study an attempt was made to study the functional properties of FPC derived from ribbon fish, Lepturacanthus savala were investigated in HDPE packaging materials and their shelf-life. The changes in chemical analysis of FPC powder prepared by Canadian process and stored at room temperature were investigated. Moisture content was increased in the range from 10.78 to 12.72 per cent, whereas the ash content was decreased in the range from 1.87 to 1.08 per cent, protein content was decreased in the range from 86.80 to 83.04 per cent and also, the fat content was decreased in the range from 0.55 to 0.40 per cent during the storage period of 180 days. The changes in functional properties of FPC powder prepared by Canadian process stored at room temperature were also investigated. The viscosity was decreased in the range from 114.00 to 100.00cP; solubility was decreased in the range from 88.92 to 83.78 per cemt, emulsification capacity was decreased in the range from 67.66 to 65.08 per cent, emulsification stability was decreased in the range from 58.84 to 56.02 per cent foaming capacity was decreased in the range from 42.50 to 32.64 per cent foaming stability was decreased in the range from 26.50 to 22.56 per cent gelation was decreased in the range from 26.50 to 20.25g. cm and also, the water holding capacity was decreased in the range from 4.27 to 3.86ml/g during the storage period of 180 days. The TPC (Total Plate Count) of the FPC powder showed increasing trend throughout the shelf-life study. The TPC of the FPC powder in storage at ambient temperature was increased from 0.42x10 2 to 1.48x10 3 cfu/g. As per microbiological quality of FPC extracted from ribbon fish, TPC value was within the acceptable limit during storage period of 180 days. The sensory qualities of FPC powder during storage at ambient temperature for 180 days were observed. For the FPC powder gradual reduction in the scores were observed with increase in the storage period. But, during storage period the sensory evaluation score indicated that the FPC extracted from ribbon fish was within the acceptable limit.

Effect of gamma radiation on microbiological changes in dry salted ribbon fish (Lepturacanthus savala, Cuvier, 1829)

A study was conducted to determine the effects of gamma radiation on microbiological qualities of dry salted ribbon fish ( Lepturacanthus savala ) collected from fish drying yard. Results of microbiological analysis showed that total plate count in non-irradiated ribbon fish was 6.9±0.15 log cfug -1 which was significantly reduced by 1 logs at 1.0 kGy, 2 to 3 logs at 3.0 kGy and 3 to 4 logs at 5.0 kGy gamma radiation. Maximum staphylococci count was noted in non-irradiated ribbon fish (3.17±0.17 log cfug -1 ) compared to irradiated with 1.0 kGy (2.63±0.50 log cfug -1 ), 3.0 kGy (2.35±0.35 log cfug -1 ) and 5.0 kGy (1.95±0.50 log cfug -1 ) on 0 th day. At the end of experiment, the halophilic count was 4.98±0.40 log cfug -1 in control while in 5.0 kGy irradiated fish sample it was 1.49±0.49 log cfug -1 . Vibrio cholera, Salmonella and Shigella and E.coli were not detected in experimental fish samples during investigation. Total fungal count recorded was 2.48±0.03 log cfug -1 in non-irradiated ribbon fish but it was totally eliminated in 5.0 kGy irradiated fish samples. Gamma irradiation doses (1.0, 3.0 and 5.0 kGy) had no significant effect (P>0.05) on sensory properties (appearance, colour, odour and texture) of dry salted ribbon fish sample neither at zero time nor during nine month storage periods. It can be concluded that, gamma irradiation dose of 3.0 and 5.0 kGy had a significant (P<0.05) effects on decreasing microbial load and improve the microbiological safety of dry salted ribbon fish without any adverse effects on their sensory quality.

ABUNDANCE AND BIOMASS ESTIMATES OF COMMERCIAL FISH SPECIES USING HYDRO-ACOUSTIC METHOD IN JAKARTA BAY, INDONESIA

The Jakarta Bay is known as a fishing ground area for several traditional types of fishing gears. The fishery has important role to provide nutrition, sustainable livelihoods, and poverty alleviation around the area. Abundance estimation of commercial fish species in the Jakarta Bay is essential particularly comparable of series data in order to evaluate the potential changes in distribution and abundance. The purpose of this study is analyzing the distribution of commercial fish species in the Jakarta Bay and estimate their abundance and biomass. Fish assemblages were concentrated in the eastern and central part of bay. Apparently salinity and DO associated with rich density of phytoplankton and zooplankton may explain the spatial variability of short-bodied mackerel and pony fish, while assemblages pattern of spiny hairtail and croaker might be driven by the availability of small planktivorous fish as their diet. The most abundant commercial fish in the Jakarta Bay are Short-bodied mackerel (&lt;em&gt;Rastrelliger brachysoma&lt;/em&gt;), Ponyfish (&lt;em&gt;Leiognathus&lt;/em&gt; sp.), Croaker (&lt;em&gt;Johnius&lt;/em&gt; sp.) dan Spiny hairtail (&lt;em&gt;Lepturacanthus savala&lt;/em&gt;) respectively. Furthermore, biomass estimates for those species showed short-bodied mackerel has the highest biomass followed by spiny hairtail, croaker, and ponyfish.

Length Frequency, Length-Weight and Relative Condition Factor of Ribbonfish, Lepturacanthus savala (Cuvier, 1829) from Karwar Waters, Karnataka State

Length frequency, length-weight and relative condition factor of Ribbonfish, Lepturacanthus savala (Cuvier, 1829) from Karwar waters, Karnataka state was studied from December 2011 to December 2012 with the object of contributing additional information to the existing knowledge. Fish samples were collected monthly by random sampling method from fish landing centre Baithkol and Karwar fish market. Total 631 specimens ranging 100-630 were studied. Total length of fish was measured from tip of the lower jaw to the tip of the tail to the nearest mm; fish were weighed nearest to 0.1 grams by using, electronic weighing balance. The length measurements were converted in to length frequencies with constant class intervals of 50 mm. The mean lengths and weights were used for data analysis. Data for male and female fish were analysed separately. Values for 'a' and 'b' coefficients were calculated and the linear regression equations were obtained by using natural logarithmic transformations. The correlation r 2 was calculated by using linear regression analysis. The relative values for Kn was determined by using equation. Obtained values for Kn were ranged between 0.9 to 1.18 for males and 0.8 to 1.16 for females.

Sex Ratio of Ribbonfish, Lepturacanthus Savala (Cuvier, 1829) From Karwar Waters, Karnataka

Sex ratio of Ribbonfish, Lepturacanthus savala has been studied from Karwar waters, Uttar Kannada District Karnataka. Sex ratio indicates the proportion of males to females in a population. This is normally expected to be 1:1 in nature. Total 631 fish were studied during the period December 2011 to December 2012. Sex ratio was calculated for different months and size groups of the fish were tested by using Chi-square (X 2 ) test. The ratio of males to females was found to be 1.7:0.5. The test of significance revealed that in January and February 2012 proportion of males and females varied significantly (X 2 = 7.89, P < 0.01 and 7.46, P < 0.01) respectively. In other months the difference was significant and the chi-square test for pooled data did not show any significant variation (X 2 = 2.28, P<0.05). The data on sex ratio in relation to size groups suggest that males outnumbered females in all the size groups. The chi-square test values for pooled data did not show much variation (X 2 =9.16, P<0.05) So far there have been some earlier reports about distribution, abundance and biological aspects but no attempt has been made towards the sex composition of Lepturacanthus

Global assessment of molecularly identified Anisakis Dujardin, 1845 (Nematoda: Anisakidae) in their teleost intermediate hosts

Here, we present the ITS ribosomal DNA (rDNA) sequence data on 330 larvae of nematodes of the genus Anisakis Dujardin, 1845 collected from 26 different bony fish species from 21 sampling locations and different climatic zones. New host records are provided for Anisakis simplex (Rudolphi, 1809) sensu stricto (s.s.) and A. pegreffli Campana-Rouget et Biocca, 1955 from Anoplopoma fimbria (Pallas) (Santa Barbara, East Pacific), A. typica (Diesing, 1860) from Caesio cuning (Bloch), Lepturacanthus savala (Cuvier) and Katsuwonus pelamis (Linnaeus) (Indonesia, West Pacific), A. simplex s.s. from Cololabis saira (Brevoort) (Hawaii, Central Pacific), A. simplex C of Nascetti et al. (1986) from Sebastolobus alascanus Bean (Santa Barbara, East Pacific) and A. physeteris Baylis, 1923 from Synaphobranchus kaupii Johnson (Namibia, East Atlantic). Comparison with host records from 60 previous molecular studies of Anisakis species reveals the teleost host range so far recorded for the genus. Perciform (57 species) and gadiform (21) fishes were the most frequently infected orders, followed by pleuronectiforms (15) and scorpaeniforms (15). Most commonly infected fish families were Scombridae (12), Gadidae (10), Carangidae (8) and Clupeidae (7), with Merluccius merluccius (Linnaeus) alone harbouring eight Anisakis species. Different intermediate host compositions implicate differing life cycles for the so far molecularly identified Anisakis sibling species.

Length-weight relationship and relative condition factor of the ribbon fish, Lepturacanthus savala (Cuvier, 1829) from the Bay of Bengal, Bangladesh

Length-weight relationship of 1119 specimens of Lepturacanthus savala (Cuvier 1829) from the Bay of Bengal, Bangladesh, was found to be curvilinear (W= 0.0003612 TL3.18) and linear (LogW= -3.44+3.18 LogTL) for both the sexes combined in arithmetic and logarithmic scales, respectively. The values of regression co-efficient (b) ranged from 3.002 to 3.337 (? ± 0.167) at 95% confidence limit. The regression 'b' value (3.18) followed the cube law and did not significantly (P&gt;0.05) differ from the cube. The growth of the fish was found to be isometric. Relative condition factor (Kn) was also within the ideal range (0.9695 to 1.1155, mean 1.001± 0.033). Seasonal or in different length groups no dramatic changes in relative condition factor were observed. Length frequency distribution was found to be normal with maximum number of fish in mid length groups and minimum in the lowest and highest length groups.

Antioxidant Activity and Amino Acid Profiling of Protein Hydrolysates from the Skin of Sphyraena barracuda and Lepturacanthus savala

The antioxidant activity of protein hydrolysates prepared from the skin of Sphyraena barracuda (Seela fish) and Lepturacanthus savala (Ribbon fish), using the commercial enzymes pepsin, trypsin, and papain were determined. The protein hydrolysate showed high antioxidant activity in which trypsin hydrolysate of the skin of both seela and ribbon fish proved good DPPH scavenging activity with 66 and 60% (p < 0.05), respectively. These active hydrolysates were purified using fast protein liquid chromatography on ion exchange and gel filtration chromatography procedure and the active purified fractions were determined using electron spin resonance spectrophotometer against 2,2-diphenyl-1-picrylhydrazyl (DPPH) and hydroxyl radicals. Further the purified fractions were analyzed for amino acid composition using high performance liquid chromatography and it consisted of antioxidant inducing amino acids along with a considerable quantity of essential amino acids.

Proximate Composition of Three Commercially Available Marine Dry Fishes (Harpodon nehereus, Johnius dussumieri and Lepturacanthus savala)

Dry fish is very common and low cost food stuff among the South-east Asian people. The nutritional aspect of dry fish is higher than the fresh fish. Dry fish is not only consumed by human but also used in fish and poultry feed formulation. The general purpose of this study is to determine the proximate composition of three available marine dry fishes namely Bombay duck (Harpodon nehereus), Sin croaker (Johnius dussumieri) and Ribbonfish (Lepturacanthus savala). Major nutrient compositions like protein, lipid, carbohydrate, moisture and ash were estimated in two different season, winter and monsoon , respectively. The results of this study is revealed that the mean percentages of protein, lipid, carbohydrate, ash and moisture content of these species ranged between 52.44-71.32, 4.92-8.64, 0-3.71, 4.68-6.72 and 14.15-33.28%, respectively. The protein and lipid content were found relatively higher in amount from the dry fish samples collected in winter season compare with monsoon season. Negative correlations were found between moisture and protein content of most of the dry fish species collected in monsoon season (r = -0.98; r = -0.96, and r = -0.95, p<0.05 for Bombay duck, Sin croaker and Ribbonfish, respectively). However, the findings are showed that marine dry fishes are highly nutritive and could be a substitute of other protein sources such as fresh fish, chicken, beef etc.

Detection of health hazard insecticide dichlorodiphenyltrichloroethane (DDT) in some common marine dry fish samples from Bangladesh

Objectives: The general purpose of this study is to detection and determination of the concentration level of dichlorodiphenyltrichloroethane (DDT) in some commercially available marine dry fishes and to investigate the contamination status of dichlorodiphenyltrichloroethane (DDT) of these dry fishes. Methods: Samples were collected from six largest dry fish markets (three from Chittagong district and three from Cox’s Bazar district) and four types of dry fishes were taken in this study are Ribbon fish (Lepturacanthus savala), Sin Croaker (Johnius dussumieri), Bombay duck (Harpodon nehereus) and Shrimp (mixed species). Total numbers of samples were 24 that were analyzed in the laboratory. Results: The results of the study show that the mean concentrations of dichlorodiphenyltrichloroethane (DDT) in the samples of Ribbon fish, Bombay duck and Sin croaker were ranged between 130.85 - 153.47ppb, 125.21 - 181.4ppb and 119.86 – 208.65ppb respectively. The mean concentrations of dichlorodiphenyltrichloroethane (DDT) were found at a lower amount in shrimp sp. than the other. Conclusions: This result indicates that the concentration of dichlorodiphenyltrichloroethane (DDT) in dry fish samples from Bangladesh are higher and may causes chronic disease and potential long-term risk for human health.

Molecular Phylogeny of the Acanthocephala (Class Palaeacanthocephala) with a Paraphyletic Assemblage of the Orders Polymorphida and Echinorhynchida

Acanthocephalans are attractive candidates as model organisms for studying the ecology and co-evolutionary history of parasitic life cycles in the marine ecosystem. Adding to earlier molecular analyses of this taxon, a total of 36 acanthocephalans belonging to the classes Archiacanthocephala (3 species), Eoacanthocephala (3 species), Palaeacanthocephala (29 species), Polyacanthocephala (1 species) and Rotifera as outgroup (3 species) were analyzed by using Bayesian Inference and Maximum Likelihood analyses of nuclear 18S rDNA sequence. This data set included three re-collected and six newly collected taxa, Bolbosoma vasculosum from Lepturacanthus savala, Filisoma rizalinum from Scatophagus argus, Rhadinorhynchus pristis from Gempylus serpens, R. lintoni from Selar crumenophthalmus, Serrasentis sagittifer from Johnius coitor, and Southwellina hispida from Epinephelus coioides, representing 5 new host and 3 new locality records. The resulting trees suggest a paraphyletic arrangement of the Echinorhynchida and Polymorphida inside the Palaeacanthocephala. This questions the placement of the genera Serrasentis and Gorgorhynchoides within the Echinorhynchida and not the Polymorphida, necessitating further insights into the systematic position of these taxa based on morphology.

Heavy metals concentration in edible fishes from coastal region of Kalpakkam, southeastern part of India

Concentrations of Cu, Mn, Zn, Fe, Cr, and Pb were estimated using ICP-MS in nine commercially important and locally consumed fish species (Sarda orientalis, Scomberomorus commerson, Rastrelliger kanagurta, Sardinella longiceps, Paraplagusia bilineata, Cynoglossus lida, Cynoglossus macrostomus, Lepturacanthus savala, and Siganus javus) collected from coastal waters of Kalpakkam, eastern part of India. Their concentration (μg g(-1)) in the examined fish species ranged as follows: Cu (0.8-6.5), Zn (14.3-27.9), Mn (0.5-8.8), Fe (17.6-117.0), Cr (0.24-1.78), and Pb (0.18-2.29). Concentrations of most of the metals in the fish species studied were found to be safe for human consumption barring Mn.

Radical Scavenging Activity of Seela (Sphyraena barracuda) and Ribbon Fish (Lepturacanthus savala) Backbone Protein Hydrolysates

We have investigated the antioxidant activity of protein hydrolysates prepared from backbones of two commercially important fishes; seela (Sphyraena barracuda) and ribbon fish (Lepturacanthus savala). Pepsin and trypsin hydrolysates were found more potent to inhibit lipid peroxidation in case of ribbon and seela fish respectively and were further purified by using fast protein liquid chromatography on anion exchange and gel filtration chromatography. The active peaks after gel filtration chromatography of seela fish was able to scavenge 2,2-diphenyl-1-picryhydrazyl and hydroxyl radicals by 61 ± 2.3 and 58.7 ± 2.3% and ribbon fish hydrolysate by 60.0 ± 2.6 and 55.6 ± 1.8% as measured by ESR spectroscopy. And the active fractions showed presence of both essential and non-essential amino acids with high percentages of arginine (11.95 and 12.76%) and lysine (13.49 and 13.89%).

Changes of Nutritional Value of Three Marine Dry Fishes (&amp;lt;i&amp;gt;Johnius dussumieri&amp;lt;/i&amp;gt;, &amp;lt;i&amp;gt;Harpodon nehereus&amp;lt;/i&amp;gt; and &amp;lt;i&amp;gt;Lepturacanthus savala&amp;lt;/i&amp;gt;) during Storage

Dry fish is the low cost dietary protein source in Bangladesh. Sometimes dry fishes are kept for a longer period that is the key factor of the deterioration of nutritional value of dry fishes, as they absorb moisture from the surrounding air. The general purpose of this study is to determine the proximate composition of three available marine dry fishes (Harpodon nehereus, Johnius dussumieri and Lepturacanthus savala) and to investigate the changes of nutritional value of these selected dry fishes with the increasing of storing period. The result of this study shows that the mean percentage of moisture content increased at a significant level with the increasing of storing period. For 2 years storing period the moisture content is increased by 12.77%, 11.89% and 6.69% for the three dry fishes (Harpodon nehereus, Johnius dussumieri and Lepturacanthus savala respectively). The result of this study also shows that the mean percentage of protein (6.35, 7.93 and 4.68), lipid (1.92, 0.67 and 1.13), and carbohydrate (1.70, 1.81 and 0.66) of three dry fishes (Harpodon nehereus, Johnius dussumieri and Lepturacanthus savala respectively) decreased greatly for 2 years storing period. The findings of this study showed that nutritional value of dry fishes deteriorate with the increasing of storage period.
