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.

Net Cage

Wadaslintang Reservoir located in Wonosobo Regency of Central Java provides to fish farming area using floating net cage. There are 2 feeding system applied that are semi intensively system managed by local community and super intensively managed by PT. Aquafarm. Both different feeding systems resulted in the amount of pollutant load coming into the reservoirs in the form of total P derived from the remaining feed and feces of fish entering into the reservoir. This can trigger the eutrophication condition of the reservoir waters. The purposes of this study were 1) to calculate the capacity of Wadaslintang reservoir to phosphorus load based on its morphometry and hydrology, 2) to evaluate the capacity of wadaslintang reservoir to Phosphorus load from floating net cage activities in wadaslintang reservoir, and 3) to design the program on the reducing load of Total Phosphorus from floating net activities in wadaslintang reservoir. The research was conducted by survey method in the Wadaslintang Reservoir during January 2016 in both locations of floating net cage fish farming. Parameters measured were P content in fish and P content of feed used in both cultivation systems, and P concentration of reservoir water. The amount of pollutant load coming into the reservoir and its impact on the P concentration of water was calculated using the formula. The results showed that Wadaslintang Reservoir to phosphorus load capacity was 106,56 ton P/year. The Phosphorus load from floating net cage was 216,2 ton P/year. The P load from PT. Aquafarm have exceeded the capacity as much as 70,74 ton P/year. In general the existence of fish farming system using floating net cage in Wadaslintang Reservoir has contributed to increase the concentration of P equal to 43,9% or in other words as much as 50% of P load that goes into reservoir of wadaslintang. Programs designed to reduce the phosphorus load could be done by reducing the number of floating net and decreasing all the activities in the catchment area up to 50% to fulfill phosphorus standard of 100 mg/m3.

To Come

It has long been known that certain species of fresh-water fish, inhabiting the rivers, lakes and ponds of India, are in the habit of leaving the water and making considerable excursions over the adjacent marshes and meadows, and some have been credited with the power of climbing trees. The older authors (Cuvier, Owen and Günther) explained the power which these fishes possessed of sustaining life outside the water by supposing that they carried with them, in reservoirs at the sides of the head, supplies of water by which the gills were kept moist. On the other hand, Taylor (1831) and specially Day (1808) and Hyrtl (1863) showed, as the result of close observation, that the reservoirs in question contained little or no water, and that the fish, when kept in tanks or globes, could be seen to come to the top at intervals and emit air-bubbles. It was, therefore, clear that the reservoirs in question contained not water but air, and that the fish must be regarded as true air-breathers. The fact that certain fish, such as Protopterus in Africa, Lepidosiren in S. America and Ceratodus in Australia, possess organs for breathing air as well as gills for respiring in water is well known; the structure and habits of these “double-breathers” (Dipnoi) form an integral part of the instruction given in every elementary course of Zoology. But the air-breathing organs of the Dipnoi are homologous with the lungs of the higher vertebrates, and the Dipnoi must be regarded as comparatively unchanged survivors from the time when the Devonian fish were making their first attempt to invade the land, at a period when no land-inhabiting air-breathing vertebrates existed.

The flood that hit Sungai Alang Village resulted in many floating net cages being lost in the flood, so many farmers lost their cages and caused losses for fish farmers. The aims of the study were to analyze: 1. The economic impact of floating net cage fish cultivators' losses. 2. The impact of social losses experienced by fish farmers. This study uses a survey method, the analysis used is business analysis and descriptive. The results of the analysis of the impact of flooding on fish cultivation in floating net cages in Sungai Alang village: 1. The economic impacts that occur are the loss of cages, loss of fish and damage to nets which result in farmers' losses. 2. The social impacts that occur are affecting the education of family members who continue to university cooperation from the community in dealing with flood disasters, changes in business due to flooding from fish farming in cages to fishing, gardening, cutting sap, raising chickens and selling vegetable.

Brachyplatystoma vaillanti is locally very common in the Amazon river, though, during my collecting tour in 1931, I examined only twenty-two examples, caught between Codajaz (nearly 1200 miles from the sea) and Gurupa. The local name of this Siluroid is Piramutāb; it is a fairly large fish (my largest specimen measuring 67 cm. in length) and possesses very long maxillary barbels (in some cases nearly as long as the body). From this fish I obtained two new species of Cestodes, one, the more numerous parasite, is a Phyllobothriid, and, so far as I am aware, this is the first occasion on which a Phyllobothriid has been described both from a fresh-water fish and from a Siluroid; and the other is a second and new species of Fuhrmann's genus Goezeella, very closely related to his G. siluri described in 1915.
