Effect of Fuel wood on the Quality of Smoked Freshwater Fish Species Sold in Tamale Central Market, Northern Region, Ghana

The study was conducted in Tamale and three villages around it. The method involved processing and smoking some raw freshwater fish species with different fuel wood species to ascertain the quality of the smokedproducts. A market survey was conducted to match the quality of the smoked products with those sold on the market and determine consumer preference on the Tamale Central Market (TCM). The results indicate thateight locally available fuel wood species produced preferred colours in the smoked fish; and have been classified as good fuel wood; while two imparted least preferred colours, and are considered bad fuel wood. All the fuelwood species had high relative efficiency (>5.5%). Thirty-one smoked freshwater fish species, belonging to 21 families were sold on the TCM. These come from 9 sources. Yeji supplied the highest quantity. Smoked freshwater fish species make a significant contribution to the economy of the Tamale Metropolis

A survey of fish species diversity and abundance in the White Volta at Nawuni, Northern Region, Ghana

The study was conducted in the White Volta River at Nawuni to identify the fishing gears used by the fishermen, assess fish species composition and their relative abundance. The results indicated that fishing gears such as gill nets, traps and hook-and-line were used. Most of the net mesh sizes used by the fishermen did not conform to those legally permitted by the Fisheries Department for inland capture fisheries. Forty-three (43) fish species belonging to seventeen (17) families were identified. The family Mochokidae had the highest species representation (7). Cichlidae were the most relatively abundant family (40%) with Sarotherodon galilaeus, scoring the greatest percentage frequency (29%). It is recommended that the use of 5.0 cm mesh size gill net should be encouraged to increase catch on a sustainable basis. Also S. galilaeus is recommended as the best species for culture based on the results of the study. It is concluded that fishing gears of mesh sizes lowerthan the recommended ones were used by the fishermen, and that the White Volta is rich in fish species diversity

Aspects of Biodiversity and Fish Production in The Kukobila Wetland in The Savelugu- Nanton District Of The Northern Region, Ghana

This study was conducted to provide baseline data on aspects of biodiversity and fish production in the Kukobila wetland. The objectives were to: identify the major animal and plant species of economic importance to the surrounding communities; identify fishing gears used and (iii) assess fish species diversity and production. Information on biodiversity was obtained through personal observation, transect walk, use of pair of binoculars and literature materials. Fish production figures were obtained by weighing daily catches of five fishermen operating in the wetland, during the dry season and in the wet season. The results indicate that Kukobila wetland has high diversity of animal and plant species that are exploited for various purposes by the local communities. Five types of fishing gears were used for exploiting the fishery resources of the wetland. Twentythree (23) fish species belonging to nineteen (19) families were encountered. Fish production was significantlyhigher during the dry season (75 000 kg) than in the wet season (45 000 kg). The high diversity probably reflects high tourism potential of the wetland

Biochemical composition of some marine fish species of Ghana

The biochemical compositions of five commercial marine fish species (Chloroscombus chrysurus, Pseudotolithus senegalensis, Sardinella aurita, Scombus japonicus and Syacium micurum) landed at the Elmina landing quay were analyzed using standard analytical techniques. The results indicate significant differences among the biochemical compositions of the five fish species studied. Moisture content ranged from 72.36% in S. japonicus (chub mackerel) to 79.06% in S. micurum (the sole fish). The least protein content(16.71%) was observed in S. micurum and the highest of 22.53% in S. japonicus. The fat content was highest for S. japonicus (15.27%) and lowest for S. micurum (3.10%). In all the five fish species studied, calcium content was highest, followed by phosphorus and iron content was the least. P. senegalensis (cassava fish), however, had higher phosphorus than calcium content. S. micurum is therefore recommended for people with over-weight (obesity) problem

Preliminary studies on copepod infestation of the garfish (,i>Ablennes hians) landed at Elmina harbour, Ghana

A study was conducted to investigate the degree and effect of copepod infestation of the buccal cavity of the gar fish landed at the Elmina harbour in Central Region of Ghana, on some body parameters and sexratio of the fish. The results indicate that the degree of infestation was significantly high (64.19%) compared to non-infestation (35.81%). The highest infestation (21.30%) occurred in animals with standard length classinterval of 75.0-79.9 cm and the least (3.40%) was in 80.0–84.9 cm. The highest infestation was recorded in the breadth class interval of 60.0-6.9 cm. The least (5.70%) was in 5.0-5.9 cm. The mean standard length of the infested animal was 74.45 ± 6.50 cm, while that of the non-infested was slightly higher (77.45 ± 6.36 cm). Mean body depth of the infested was slightly lower (6.94 ± 0.86 cm) than that of the non-infested (7.08 ± 0.94 cm). Mean condition indices of infested and non-infested garfishes were similar (about 1.42 x 10-1) for each group. Sex ratios of infested (1:1.02) and non-infested (1:1.36) did not differ significantly. Similarly, the standard length-gill length and gill volume of infested and non-infested garfishes were close to each other, but slightly more positive for the non-infested animals. Finally, the results of biochemical composition indicate that the various components did not differ significantly between infested and non-infested. Protein content was high(20.30%), but fat content was rather low (8.50%) for both infested and non-infested garfishes. It is concluded that infestation had no significantly negative effect on the garfish
