    Description: This study was carried out by surveying all the water bodies of two states where Typha grass exists. Soil auger was used to take soil samples randomly from five different locations in both Kebbi and Katsina state at the depths of 0-5cm, 510cm, 10 15cm. Soil nutrient was analyzed for the mineral composition of the two States at different season and soil depths. The result showed that, soil depth between 5-10cm has the highest percentage of nitrogen, phosphorus, calcium and magnesium during dry season. The nutrient composition of soil from the two states followed the same pattern during wet season.

    Description: The impact of Typha grass of fish catch composition of different water bodies in Kebbi State was studied. The experimental fishing was conducted, each water body was divided into.A and B. A was open water while B was Typha infested area. Five Malian traps were set in eacharea (A and B) fer five consecutive fishing days respectively. The fish caught was identified,counted and measured (weight).The various parameters of the plant (Typha grass) were also. measured and counted. The results en fish catch composition in terms of numbers and weight in open water was higher than Typha infested area in both dry and wet seasons.

    Description: Field identification of Typha species in Hadeja Gashua Nguru wetlands Nigeria between January/June 2008. and July/October 2008. The study was conducted at Gashua Nguru wetland (Yobe and Jigawa states), Nigeria. The three sampling stations were established. Aquatic Plant Control information system Table (1996), for identify the species of Typha species was used, in three sampling station. Two Typha species were identified T. latifolia and T. angustifolia. Data analysis showed that, there was significant difference between T. latifolia and T. angustifolia (P〈0.05).

    Impact of seasonal variation on population of weevils (Neochetina spp) (2021)

    Description: The impact of seasonal variation on population of weevils (Neochetina Spp), commonly used as water hyacinth bio-control agent was carried out in the National Institute for Freshwater Fisheries Research water-hyacinth insect laboratory. The experiment was conducted between May 2006 and April, 2007. Ten plastic containers of 50cm depth, 60cm diameter and 20-litre capacity each filled with 16- litters of water and 20 bunches of water hyacinth were used for the experiment. Ten weevils made up of five male and five female were introduced into each of the plastics container. The weevils were monitored daily, their numbers recorded. The result showed that, during wet season (May to October) the population of weevils increased, while it decreased during the dry season (November to April). Data analysis showed that, there was significant difference between wet season and dry season (P〈0.05).

    Description: The response of Typha australis to stem cut at three different heights was studied for four weeks. This was carried out in the field between August and September 2003. Matured Typha australis naturally occuring along the stream within the Institute Integrated Fish Pond Complex, New Bussa were randomly selected. The shoots were cut at 10cm, 20cm, and 30cm, above the soil level. The responses of the plant were assessed. Plant cut at 10cm showed re-growth for one week and later died, while those cut at 20cm and 30cm showed re-growth through out the period of experiment. Result showed previous height between 10cm and 20cm is significant (P〉0.05) between 10cm and 30cm height re-growth rates. But plant cut at 20cm and 30cm showed no significant (P〉0.05), in height. The results show the susceptibility of Typha australis to stem cut at 10cm or below. Typha australis cut at 10cm above soil level are not likely to survival
