Abstract. Muscle portion of 72 fish samples of eight selected species, four from marine (Pampus Chinensis, Otolithes ruber, Trachipteridae and Oncorhynchus tshawytscha) and four from fresh water (Labeo rohita, Catla catla, Rita rita and Walago atu) fishes were collected from three superstores in Lahore, Pakistan. The prepared fish samples were analyzed for determination of Chromium (Cr), Lead (Pb) and Cadmium (Cd) concentrations by using the inductively coupled plasma (PerkinElmer, Model: Optima 7000DV ICP-OES). It was found that Cd (0.294±0.001 mg/kg) concentration was the highest in Labeo rohita collected from Metro Superstore while the lowest level (0.023±0.000 mg/kg) was in the Oncorhynchus tshawytscha of the same superstore. Species wise concentration of Cd varies significantly. Concentration of Cr (0.172±0.001mg/kg) was the highest in Oncorhynchus tshawytscha collected from Main Fish Market of Lahore while the lowest level (0.002±0.001mg/kg) was in Labeo rohita collected from Hyperstar superstore. Concentration of Pb (0.057±0.000mg/kg) was the highest in Oncorhynchus tshawytscha collected from Metro Superstore while the lowest (0.012±0.001mg/kg) in Otolithes ruber of the same superstore. Species wise concentration of Pb varies non-significantly. Origin wise t-test shows that: a) Cd concentrations vary significantly, while Cr and Pb concentrations vary non-significantly when marine and fresh water species were compared. b) The range of Pb (0.011-0.057 mg/kg) and Cr (0.002-0.172 mg/kg) was within limits and of Cd (0.023-0.297 mg/kg) was higher than the WHO international standards (0.123 mg/kg for Pb, 0.050 mg/kg for Cd and 0.1 mg/kg for Cr) in most of the fish species of main Fish Market Lahore, Hyperstar and Metro store.


Consumers all over the world are increasingly becoming aware of the health and nutrition status of fish and fishery products. There have develop some preference for fish species and even their processing methods. This study aims to investigate the effects of two drying methods (smoking and oven drying) on the biochemical components and organoleptic properties of two less preferred food fishes abundant in the study area. The fish samples Mormyrus rume and Labeo coubie were purchased from fresh landings of fishermen at Ahaha beach. The biochemical assay of the moisture, protein, fat, carbohydrate, ash, calcium (Ca), magnesium (Mg), phosphorus (P), iron (Fe), sodium (Na) and potassium (K) were conducted in the labouratory using standard methods. The proximate composition of raw M. rume was determined as moisture 70.38%, protein 17.43%, carbohydrate 1.13%, fat 5.93% and ash 2.77% while oven dried were 18.78, 63.85, 3.37, 8.73 and 7.58% respectively. All the proximate parameters and gross energy level investigated were higher (p < 0.05) in M. rume except the moisture content of dried samples of L. coubie. The mineral content were in the order Ca < Mg < Fe < Na < P and < K in both species and were higher in M. rume except Na. The drying methods showed increase in the proximate and mineral compositions in the order raw < smoking and < oven drying except moisture content that decreased respectively is both species. Organoleptic properties revealed that dried samples (smoked and oven) were not significantly different (p < 0.05) in taste, flavour, texture and overall acceptance, however while oven dried had better colour (4.33), smoked dried taste (4.63) better. The drying methods shows concentration of the required nutrients in human diets and were also found to be most palatable by the panellist. To improve fish nutrient quality smoke and oven drying should be encourage.

Ciguatera fish poisoning (CFP) is one of the most frequently reported seafood poisoning diseases. It is endemic to the tropical region and occurs most commonly in the regions around the Pacific Ocean, Indian Ocean, and Caribbean Sea. The principal toxins causing CFP are ciguatoxins (CTXs). In the Pacific region, more than 20 analogs of CTXs have been identified to date. Based on their skeletal structures, they are classified into CTX1B-type and CTX3C-type toxins. We have previously reported species-specific and regional-specific toxin profiles. In this study, the levels and profiles of CTXs in fish present in the tropical western Pacific regions were analyzed using the liquid chromatography–tandem mass spectrometry (LC–MS/MS) technique. Forty-two fish specimens, belonging to the categories of snappers, groupers, Spanish mackerel, and moray eel, were purchased from various places such as Fiji, the Philippines, Thailand, and Taiwan. Only the fish captured from Fijian coastal waters contained detectable amounts of CTXs. The toxin levels in the fish species found along the coastal regions of the Viti Levu Island, the main island in Fiji, and the toxin profiles were significantly different from those of the fish species present in other coastal regions. The toxin levels and profiles varied among the different fish samples collected from different coastal areas. Based on the toxin levels and toxin profiles, the coast was demarcated into three zones. In Zone-1, which covers the northern coast of the main island and the regions of the Malake Island and Korovau, CTXs in fish were below the detection level. In Zone-2, CTX3C-type toxins were present in low levels in the fish. CTX1B-type and CTX3C-type toxins co-occurred in the fish present in Zone-3. The toxin profiles may have reflected the variation in Gambierdiscus spp.

Understudying the presence of bacteria and fungi population on freshwater fishes, provides the knowledge and understanding of their diversity and potential roles they may play in the health of the aquatic and terrestrial ecosystems. The present study was conducted to evaluate the diversity of bacteria and fungi species of identified fish samples from River Mijawal, Nasarawa State. The fishes were sampled from the only landing for three months (October to December, 2019) for this study. During the sampling periods, thirteen (13) different fish species were identified; they were  swabbed with sterilized swab stick from the skin surface for bacteria and fungi identification. The Dominant fish species were Tilapia zillii, Labeo senegalensis, Mormyrus rume and Mormyrus tapines. The total number of thirteen (13) bacterial and five (5) fungi species were isolated and  identified. Eight (8) of the bacteria isolates, were gram negative bacteria (Pseudomonas sp, Aeromonas sp, Serratia mercescenes, Proteus sp, Salmonella spp, Escherichia coli, Klebsiella sp, and Enterobacter sp.); whilst the other five (5) were gram positive bacteria (Bacillus sp, Micrococcus sp, Staphylococcus sp, Enterococcus sp and Listeria monocytogenes).The five isolated fungi species were Aspergillus niger, Rhizopus sp, Penicillium  sp, Trichoderma viridae and Geotrichum candidum. The frequency of occurrence of the isolated bacteria indicated that Staphylococcus sp had the highest frequency of occurrence (16.67%) while Serratia mercescens had the least occurrence (2.78%). The highest number of occurrence of the isolated fungi species was observed in Rhizopus sp while the least was recorded in Geotricum candidum. It was observed that Tilapia zillii and  Mormyrus rume had the most frequent bacteria and fungi isolates. It can therefore be deduced from the results that fish samples identified from River Mijawal has high bacteria and fungi diversity that may be pathogenic to man. The occurrence of these microbes may be attributed of human  and animal faeces in the River  Keywords: Freshwater fishes, Microbes, River Mijawal, Nasarawa

Introduksi ikan nila atau “serapia” (Oreochromis niloticus) di Danau Paniai bertujuan untuk meningkatkan diversitas hasil tangkapan dan mengurangi tekanan eksploitasi terhadap jenis ikan endemik. Pertumbuhan dan produksi ikan nila yang cepat tanpa diiringi upaya pengelolaan akan mengancam keberlanjutan ikan endemik di danau. Upaya pengelolaan sumberdaya ikan di suatu perairan membutuhkan informasi dinamika populasi. Penelitian dinamika dan pengelolaan populasi ikan nila dilakukan pada bulan Februari sampai Oktober 2016. Contoh ikan dikumpulkan dari hasil tangkapan nelayan dengan menggunakan jaring insang dengan berbagai ukuran mata jaring dan dari 4 (empat) enumerator pada tujuh stasiun pengamatan. Hasil penelitian menunjukkan populasi ikan nila di Danau Paniai didominasi ukuran panjang individu antara 15-25 cm sebanyak 67,24%. Pola pertumbuhan ikan jantan dan betina adalah isometrik, panjang maksimum rata-rata (L) adalah 37,28 cm dan koefisien pertumbuhan (K) adalah 0,50 per tahun. Mortalitas alami (M) dan mortalitas penangkapan (F) masing-masing sebesar 0,99 dan 0,54 per tahun. Tingkat eksploitasi (E) diperoleh nilai 0,35 lebih kecil dari nilai optimum (E=0,5). Ukuran rata-rata ikan nila tertangkap (Lc) adalah 20,55 cm lebih besar dari ukuran pertama matang gonad (Lm) sebesar 14,73 cm. Nilai Lc>Lm mengindikasikan sebagian besar populasi ikan nila di Danau Paniai sempat melakukan pemijahan sehingga pemanfaatan lebih atau sama dengan nilai optimum diharapkan dapat meningkatkan pemanfataan ikan nila di Danau Paniai. Introduction of nile tilapia (Oreochromis niloticus) in Lake Paniai known as “serapia” is aimed for improving the diversity of catches and reducing the exploitation pressure on the endemic fish species. The rapid growth, reproduction and production of nile tilapia without its management efforts is a new threat to the sustainability of the existence and utilization of endemic fish species in the lake. Management efforts of fish resources require population dynamics information. Research on the dynamics and management of nile tilapia populations was conducted from February to October 2016. Fish samples were collected from fishermen catches using nets with various mesh sizes and from four enumerators at seven observation stations. The results showed that the population of nile tilapia in Lake Paniai was dominated by individual length between 15-25 cm with frequency of 67,24%. The growth pattern of male and female fish were isometric, the average maximum length (L) was 37.28 cm and the growth coefficient (K) was 0.50 per year. Natural mortality (M) and fishing mortality (F) were 0.99 and 0.54 per year respectively. Exploitation rate (E) of 0.35 was smaller than the optimum value (E=0.5). The average size of nile tilapia captured (Lc) was 20.55 cm larger than the first size of gonad maturity (Lm) of 14.73 cm. The Lc value was higher than that the Lm value(Lc>Lm) indicating that most of nile tilapia population in Lake Paniai has spawned so that increasing the more or equal to the optimum value was expected to improve the of nile tilapia fish in Lake Paniai.

This study was conducted to investigate the stomach contents of two commercially important fish species (Tilapia zilli and Oreochromis nilocticus)  from Wanzun River, Northcentral Nigeria using frequency of occurrence and volumetric methods between January to April 2019. Fish samples were collected monthly with help of Fishermen using various fishing nets and traps. One hundred (100) individual fish of each species were collected and their stomach contents were examined. The results obtained expressed in mean percentage indicated that out of the one hundred (100) individual fish of each species examined,Twelve (12%) fish had an empty stomach contents in Tilapia zilli, and out of the 100 samples examined, Seventeen (17%) fish had an empty stomach content in Oreochromis nilocticus. The stomach contents of both Tilapia zilli and Oreochromis nilocticus consist of detritus, insects, fish remains. Algae/protozoans plant materials and molluscs. Both fish species are omnivorous feeders and occupy the same ecological niche.The study reveals the importance of algae, fish, insects and plant materials as food for fishes and they form important part in the diet of the species examined.

Keban Dam Lake is the second largest dam lake in Turkey. In addition, it has the feature of being one of the most important dam lakes in our country in terms of both aquaculture potential and electricity generation. In this study, fish samples belong to Capoeta trutta caught from Örencik region of Keban Dam Lake were used. The concentrations of some heavy metals (copper, iron, zinc, chromium, nickel, cadmium, arsenic and mercury) in muscle of Capoeta trutta and the potential health risk from consumption of this fish species were examined. In addidion, the relationship between the heavy metal levels and some biological aspects of fish (weight, length and sex) were determined. As a result of the study, it was determined that the most and the least accumulated heavy metals in the muscle tissue of Capoeta trutta were zinc and cadmium respectively. The concentration of heavy metals showed differences according to weight, length and sex of fish. The results were found indicated that heavy metal levels in the muscle tissue of Capoeta trutta are below the tolerable values recommended by EPA, WHO and FAO. Therefore, there is not any risk for human consumption of this fish species.

Seafood, especially in traditional food Taiwan, is rarely sourced from a fixed species and routinely from similar species depending on their availability. Hence, the species composition of seafood can be complicated. While a DNA-based approach has been routinely utilized for species identification, a large scale of seafood identification in fish markets and restaurants could be challenging (e.g., elevated cost and time-consuming only for a limited number of species identification). In the present study, we aimed to identify the majority of fish species potentially consumed in fish markets and nearby seafood restaurants using environmental DNA (eDNA) metabarcoding. Four eDNA samplings from a local fish market and nearby seafood restaurants were conducted using Sterivex cartridges. Nineteen universal primers previously validated for fish species identification were utilized to amplify the fragments of mitochondrial DNA (12S, COI, ND5) of species in eDNA samples and sequenced with NovaSeq 6000 sequencing. A total of 153 fish species have been identified based on 417 fish related operational taxonomic units (OTUs) generated from 50,534,995 reads. Principal Coordinate Analysis (PCoA) further showed the differences in fish species between the sampling times and sampling sites. Of these fish species, 22 chondrichthyan fish, 14 Anguilliformes species, and 15 Serranidae species were respectively associated with smoked sharks, braised moray eels, and grouper fish soups. To our best knowledge, this work represents the first study to demonstrate the feasibility of a large scale of seafood identification using eDNA metabarcoding approach. Our findings also imply the species diversity in traditional seafood might be seriously underestimated and crucial for the conservation and management of marine resources.

Fishes are world widely consumed by all categories of works of life because of their richness in protein, readily available and affordable by all. The basic nutrient of protein in fish that is so important in man’s diet also attracted microorganisms for their growth and multiplication. Meanwhile, the association of microorganisms in fishes depend on the environment of culture and their proliferation due to inadequate storage facilities. The aim of this study was focused on the isolation and identification of microorganisms from four frozen fish species sold in the Ado Ekiti metropolis. Frozen fish samples of Scomber scombrus (Atlantic Mackerel), Clupea harengus (Atlantic herring), Urophycis tenuis (White hake or mud hake) and Trachurus trachurus (Atlantic horse mackerel) from two markets in Ado Ekiti were microbiologically analyzed for possible microbial contamination. On the fish samples, the total heterotrophic count (THC) was 3.5×104 – 5.6×104 CFU/g, total coliform count (TCC) was 2.4×104 – 5.1×104 CFU/g, total Salmonella/Shigella count (TSSC) was 1.3×104 – 3.5×104 CFU/g, total Vibrio count (TVC) was 1.1×104 – 2.3×104 CFU/g and total fungal count (TFC) was 1.3×103 – 2.3×103 Spore/g were analyzed by cultural methods. There were variations in microbial loads among the fish species in the surveyed markets. The microorganisms identified with their percentage occurrence were Bacillus cereus (11.54%), Streptococcus faecium (13.46%), Alcaligenes faecalis (5.77%), Salmonella enterica serovar Typhi (5.77%), Micrococcus luteus (9.62%), Vibrio cholerae (7.69%), Aerococcus viridans (3.85%), Pseudomonas aeruginosa (7.69%), Xanthomonas fragariae (7.69%), Staphylococcus aureus (11.54%), Clostridium butyricum (7.68%), Escherichia coli (7.69%), Aspergillus fumigatus (11.11%), Aspergillus flavus (24.44%), Aspergillus clavatus (8.89%), Aspergillus fishcheri (6.69%), Aspergillus terreus (8.89%), Mucor mucedo (17.78%), Penicillium digitatum (13.33%) and Aspergillus parasiticus (8.89%). The results emphasized the microbial contamination of the fishes. The results obtained could serve as an awareness to consumers that microbial infection is possible from frozen fishes and as data for future reference in epidemiology or outbreak of disease from eating frozen fish.
