Physico-chemical Parameters and Heavy Metals Distribution in Selected Shell Fishes along the Opuro-Ama Creek in Rivers State of Nigeria
No full textThe study was conducted to determine the heavy metals concentration in selected shell fishes (U. tangeri, C. amnicola, T. fuscatus, P. monodon), sediment and water. The samples were collected from a fishing port along the Opuro-ama Creek in Rivers State of Nigeria. analysis for Manganese (Mn), Iron (Fe), Cobalt (Co) and Zinc (Zn) were done using Atomic Absorption Spectrophotometer. The order of metal accumulation in these shellfishes, sediment and water were; C. amnicola (Fe > Zn > Cu > Co > Mn); U. tangeri (Fe > Zn > Cu > Co > Mn); T. fuscatus (Fe > Cu > Zn > Co > Mn); P. monodon (Fe > Co > Zn > Cu = Mn); Sediment (Fe > Zn > Co > Cu > Mn); Water (Fe > Cu > Mn > Co = Zn). There was statistical difference (p<0.05) in metals concentration in the soft tissues in all the shellfish. From the results, the concentration of the metals in the tissues of all the shell fishes, the interstitial water and the sediment sampled from the creek were within the permissible limit recommended by the Department of Petroleum Resources (DRP), Environmental Protection Agency (EPA) and World Health Organization (WHO) except for Fe which was above the recommended limit. The physicochemical parameters of the interstitial water such as pH, Temperature, Conductivity, Total Dissolved Solids (TSS) Biological Oxygen Demand (BOD), Dissolved Oxygen (DO), and Salinity were within the acceptable levels in the guidelines for drinking]. Although Chemical Oxygen Demand (COD) and the Total Suspended Solids (TSS) were slightly higher than the recommended limit of these metals by Department of Petroleum Resources (DRP). This indicates that if theses metals are not checked, they may increase the potential for bioaccumulation in the shellfishes and the creek as well. Therefore, there is need for regular monitoring of this creek to avoid future deterioration

Analysis of Sales Marketing Margins and Marketing Efficiency of Gillnet Fisherman in Nusantara Fishery Port Palabuhanratu, Sukabumi
No full textThe marketing process of gillnet fishing catch sales in Palabuhanratu is not balanced. Gillnet fishing catch sales are not through auction due to the small catch. So that fishermen have no other way than to sell the catch to middlemen because of the consequences of capital borrowing. This study aims to determine marketing activities and marketing margins, costs and profits fisherman gillnets at the Palabuhanratu Nusantara Fishing Port, Sukabumi. This research was conducted from February 2022 to June 2022. The method used is a descriptive method with a case study approach. The types of data used is primary data by using a questionnaire. The sampling technique used in this research is snowball sampling. A snowball sampling technique is a step in selecting sources at the time in the field or based on previous informants\u27 instructions so that researchers get complete and in-depth data. Based on the data analysis, The biggest cost are on channel II range from IDR 3.800- IDR 15.500 Followed by channel IV range from IDR 6.150- IDR 14.000 and the lowest is channel III range from IDR 3000- IDR 7.000. The higest profit is channel II range from IDR 8.200- IDR 17.970 and the lowest profit is channel III range from IDR 1.200- IDR 6.000. The marketing channel that has the smallest marketing margin and the largest share margin is channel type 3, with a margin value of between IDR. 10,000-IDR.5,000 with an average of IDR. 6,700,- and share margins ranging from 64.28% - 77.78% with an average of 71.6% followed by type 1 channels with marketing margins ranging from IDR.7,000-IDR.20,000 with an average of IDR.11,800, - and share margin ranging from 63.3% - 72% with an average of 67.28%.The results showed that there are 4 patterns of marketing channels, where the most efficient marketing channel is through channel type three followed by channel type one. However, it should be underlined that marketing efficiency is not only seen from marketing margins and share margins, although type 3 channel is the most efficient channel, but when viewed from the quality and freshness of fish, type 1 channel is better. To be able to increase the income of fishermen should process abundant fish products into frozen food so that it can be absorbed by the market. In addition, there is a need for government agencies that are able to fight for fishermen in obtaining capital and reactivating existing cooperatives

Fatty Acids Composition of Two Commonly Consumed Freshwater Fishes (Clarias gariepinus and Chrysichthyes nigrodigitatus) from the Cross River at Ahaha, Obubra, Nigeria
No full textFish oils are good sources of essential fatty acids beneficial to human health by helping the body in preventing diseases and enhancing proper growth and development. This study is aimed at investigating the quantitative and qualitative composition of fatty acids in two commonly consumed and most abundant freshwater fishes (Clarias gariepinus and Chrysichthyes nigrodigitatus) from the Cross River at Ahaha, Obubra. The oil was converted to fatty acids methyl esters (FAME) and the fatty acids evaluated by gas chromatography – mass spectrometry using retention time method. The fatty acids profiles include saturated fatty acids (SFAs), monounsaturated fatty acids (MUFAs) and polyunsaturated fatty acids (PUFAs). The composition varied from 0.06 – 24.00% of SFAs, 0.23 – 21.40% of MUFAs and 0.23 – 12.22% of PUFAs in the both species. The major SFAs were palmitic (C16:0) and stearic (C18:0) acids while the most abundant MUFA was oleic (C18:1) acid. Dominant PUFAs in the both specie were linoleic (C18:2), eicosapentaenoic (EPA, C20:5) and docosahexaenoic (DHA, C22:6) acids. Quantitatively the composition of various fatty acids was in the order SFAs < MUFAs < PUFAs although not significantly different (p< 0.05) in the species. Chrysichthys nigrodigitatus had higher total fatty acids (TFA), PUFAs and omega –3 / omega –6 ratio than C. gariepinus with higher levels omega -6 fatty acids. The ratios of PUFA/SFA were higher in C. nigrodigitatus although both were greater than the minimum value (0.4) recommended by World Health Organization. The result indicates that the species had high quality essential fatty acids especially DHA and EPA although relatively higher in C. nigrodigitatus. Hence these species have the potentials to serve as the natural dietary supplement for all important omega -3 fatty acids
The Effect of Adding Catfish Bone Flour on the Preference Level of Catfish Meatballs
No full textCatfish is a commodity in great demand by the Indonesian people because it is easy to process. The utilization of fish bone waste is not optimal because many people only use meat. Fish bones can be processed into flour as a food additive with high calcium. This research aims to determine the appropriate percentage of catfish bone flour added to catfish meatballs and its effects on the preference level among the panelists. This research was conducted at the Fishery Product Processing Laboratory, Faculty of Fisheries and Marine Sciences, Universitas Padjadjaran. This research used an experimental method with 5 treatments of adding catfish bone flour into catfish meatballs: 0%, 5%, 10%, 15%, and 20%. The assessment of the level of preference was carried out by 20 semi-trained panelists. This research observed the organoleptic attributes (appearance, aroma, taste, and texture) and physical characteristic (folding test). Statistical analysis of this research used non-parametric statistics such as Friedman test, followed by a multiple comparison test, and determined the best treatment using the Bayes method. The results of statistical analysis and Bayes showed that the addition of 10% catfish bone flour to catfish meatballs was the best treatment preferred by the panelists
