Notopterus Notopterus

Hematological and some biochemical contents of the blood in relation to physico-chemical characteristics of the water have been studied in the fresh water fish, Notopterus notopterus. The results indicated that normal values have been found in comparison to the studies carried out in other fishes. Hence, the fish Notopterus notopterus is having favorable environmental temperature, pH and dissolved oxygen required for the fish to survive and regulate breeding activities.

Water chemistry is thought to be the primary factor influencing fish otolith chemistry. Experimental results with freshwater and diadromous fish have been consistent with this paradigm, but with marine fish, they have often been ambiguous or contradictory. A review of water chemistry data indicated that Sr:Ca (mmol:mol) levels were higher in marine water than in most freshwater systems and that Sr:Ca variability was lower in marine water than in most freshwater systems. We therefore hypothesized that lifetime otolith Sr:Ca profiles of freshwater fish would exhibit low levels of Sr:Ca with moderate variability, of diadromous fish would exhibit highly variable Sr:Ca levels, and of marine fish would exhibit high levels of Sr:Ca with low variability. Otolith Sr:Ca profiles from 81 species of freshwater, diadromous, and marine fish revealed that freshwater fish had low levels of Sr:Ca and lower variability than expected relative to marine fish, diadromous fish had Sr:Ca levels and variability that were consistent with expectations, and marine fish had high maximum Sr:Ca levels, as expected, and high Sr:Ca variability, similar in magnitude to diadromous fish, which was not expected. These findings indicate that water Sr:Ca is the primary factor influencing otolith Sr:Ca variation for freshwater and diadromous fish but not for marine fish.

Fish Productivity

Freshwater fish farming in West Bangka Regency is developing to meet the needs of the local market. Information about the distribution and production of fish farmers groups (Pokdakan) can be used as a basis for planning sustainable development. This research was conducted using a survey method in July - September 2019 in Muntok District, West Bangka Regency. Fifteen Pokdakan scattered in seven villages with the majority developing catfish commodities. There is only one group that belongs to the middle class, while the other group is still in the beginner class. Freshwater fish productivity reaches 3.2 tons per quarter. The majority of Pokdakan utilize former tin mines with step-in-net cage for fish farming so that their productivity is affected by the season. Continuity of production is needed so that the class of Pokdakan can increase.

The present investigation deals with the study of cestode host relationship in a fresh water fish, Mastacembelus armatus (Lacepede) in relation to the body temperature of the host. The maximum prevalence, mean intensity and relative density were recorded in the host fish ranging from 26-31°C and lowest at 32- 370C body temperature respectively . The fishes at 20-250C body temperature had no infection of cestode parasites.

The study was done to review some saltwater and freshwater fish species in the Niger Delta region of Nigeria. The Niger Delta is one of the most prominent regions in Nigeria, endowed with several water bodies that are distributed as freshwater like rivers, lakes, streams and creeks. These freshwater ecosystems in the region, are abundantly endowed with fish species such as Clarias gariepinus, Pila ovate, Labeo coubie, Synodontis budgetti and Synodontis eupterus. Apart from the freshwaters, the region also has vast marine ecosystem with abundance of fish species such as Elops lacerta, Mugil cephalus, Thais coronata, Periophthalmus papilio, Tympanotonus fuscatus, and Sardinella maderensis. Unfortunately, many of these fish species are endangered due to constant pollution in the Niger delta regional coastal environment. As a result, it is important to document some available freshwater and marine water fish species which will serve as a reference material for both academics and research institutions, should any of the fish species go into extinction.
