Jammu and Kashmir serves a congenial habitat for variety of fish species due to large number of cold water resources which has paved way for the development of fisheries sector in the state. The state has crossed 20.0 thousand tonnes of fish production because of modern aquacultural practices implied at both governmental and private levels. Kashmir province is a leading producer of fishes contributing more than 80% of the total production of the state while as Jammu on the other hand has also emerged as a major producer of animal protein through fisheries sector. The fish production data of four decades reflects increasing trend of production in all commercially important species of both the provinces. However the statistical models forecasting the future production provide an idea about the growth patterns in fishes. In this paper, growth pattern of three different fish species (Trout, Mirror carp and Country fish) from Kashmir province and various fishes from Jammu province (collectively named as Jammu fish) of the state was assessed using fish production data from 1956-57 to 2011-12. Forecasting of fish production was made on the basis of the best fitted statistical models. Results showed that Kashmir province shows overall compound growth of 4.2% against 7.9% of increased compound growth rate of fish production of Jammu province since 1956-57. Cubic model was found to be the best fitted model for all the species in both the regions. However, when future fish production of the state is taken into consideration, the statistical models indicated a decreasing trend in the overall fish production of both the provinces. Besides, the matter of concern is that the demand of 70,000 thousand tonne consumption of fish protein in the state which is a milestone yet to be achieved.

In the Himalayan states of India, the mountainous region is rich in abundant oxygen, fresh water, which is highly suitable for the cultivation of rainbow trout. Himachal Pradesh is a state with many streams and reservoirs and has a large capacity of fish production. Estimated fishery, water resources of the state are about 3000 km, out of which 600 km of cold water streams are suitable for trout cultivation, which can be used for culturing trout. Trout is a cold water fish that grows well in water temperature from 5 oC to 15oC. There are approximately 762 trout forms, including seven run by the government in the state, which are mainly in Kullu, Chamba, Shimla, Kinnaur and Mandi districts. Out of the five zones, there are vast possibilities of producing high prized fish trout in Zone 1 and 2 of Himachal Pradesh. The total production of trout in the state was 0.54 tonnes in 1996-97 and increased to 25 tonnes in 2005-06, compared to 456.73 MT in 2017-2018. Availability of technical information on trout cultivation, breeding and artificial diet has helped tremendously in promoting the aquaculture of trout in the state. Extension and development efforts of rainbow trout production have led to an overall increase in the production of trout fish, but still there is a big difference between the actual and potential trout production. This paper has reviewed its ability to produce trout, present status and future expansion in Himachal Pradesh.

Fish species richness in floodplain pools results from species addition by spring invasion from the stream and species subtraction by local extinction throughout the summer. Local extinction is the more important of the two components. Nineteen floodplain pools (1 to 597 m2) and an adjacent section of Irvine Creek (43°44′ N, 80°25′ W), Ontario, Canada, were treated with a piscicide to test if the pools contribute significantly to the resource potential of the river basin. Altogether, 41 626 fishes of 20 species were collected. Number of days of stream connection in the spring was not significantly correlated with fish species richness in the pools (P < 0.10). A significant correlation (P < 0.05, r = 0.7413) was found between species richness and the logarithm of pool area. The total fish production for the Irvine Creek section, adjusted to account for dominant and nondominant species, was 298 kg∙ha−∙year−1. Production for this site was underestimated by 49% when weights and densities were backcalculated to time of annulus formation. Total production estimates of the floodplain pools ranged from 135 to 314 kg∙ha−1∙year−1. Stream connection duration affects pool fish production by regulating accessibility to the young of stream spawning species. Floodplain pools are beneficial to the Irvine Creek system. As nursery areas, floodplain pools produce fish biomass which can return to the stream during periods of stream–pool connection. These pools may also act as fish havens if catastrophic stream mortality occurs.

Kaptai Lake (KL), the largest artificial lake in Bangladesh, supports an important inland open water fishery. Nevertheless, detailed studies on its fish diversity and environmental threats are still limited. Hence, a study was conducted to evaluate the current fish management scenarios, fish production, relative abundance to improve the production and biodiversity of KL. Data were collected from stakeholders through personal observation, focus group discussions, and cross-check interviews from September 2018 to July 2019. The fish production of KL increased from 1,200 metric tons (MT) in 1965–1966 to 10,577 MT in 2018–2019. The output of the lake was dominated by small fish remarkably, Gudusia chapra (Hamilton, 1822), Gonialosa manmina (Hamilton, 1822), and Corica soborna Hamilton, 1822, accounting for 64 % of the total production in 2018–2019. A total of seventy-six fish species were observed under ten orders, including seven exotic fish species. According to the IUCN Bangladesh, 14 % of total species were identified as vulnerable, 11 % as endangered, 3 % as critically endangered, 11 % as near threatened and 51 % as least concern. The study also identified that climate change and various human-driven causes threaten the fish production and biodiversity of this lake. These findings suggest that community-based fisheries management, protection of natural breeding grounds of carps, control of pollution, amendment of existing fishing laws, and collaborative research would be a necessary approach for mitigating the negative environmental impact of this lake. The overall practical knowledge of this investigation could assist in policymaking and further research.

Time Changes

This article considers the direct connection of the state of living of the population with the structures of the economy. In this regard, it is noted that the territorial aspects of the structure of the economy are also factors in shaping the structure of people 's needs, despite the fact that the latter are poorly structured. The study showed that the extent of structural changes in the economy, apart from the needs of the population, is affected by such critical proportions as the ratio of production to consumption, the savings fund to consumption fund, industry and agriculture, growth of production and transport development, growth of cash incomes of the population and their commodity coverage. In total production theoretical analysis has also shown that structural changes in the economy depend on the level of change in the share of each sector of the economy At the same time, changes also affect economic growth and human well-being in different ways.

The first empirical task is to identify the characteristics of municipalities which US-based migrants have come together to support financially. Using a nationwide, municipal-level data set compiled by the author, the chapter estimates several multivariate statistical models to compare municipalities that did not benefit from the 3x1 Program for Migrants with those that did, and seeks to explain variation in the number and value of 3x1 projects. The analysis shows that migrants are more likely to contribute where migrant civil society has become more deeply institutionalized at the state level and in places with longer histories as migrant-sending places. Furthermore, the results suggest that political factors are at play, as projects have disproportionately benefited states and municipalities where the PAN had a stronger presence, with fewer occurring elsewhere.

Fish Farms

Brazilian fish farms presented an accelerated development during the early 90's, mainly because of the increase in fee-fishing operations. To meet the demand of this market, fish production and supply became excessive and, as a consequence, the number of fee-fishing operations, farmers and the final selling price, decreased. This study analyzes the technical aspects, production cost, profitability and economic viability of the production of piauçu (L. macrocephalus) in ponds, based on information from a rural property. Feeding and fingerling costs amount to approximately 47.1% of the total production cost, representing together with the final selling price the most important factor affecting profitability. The payback period was 8.3 years, the liquid present value US$ 291.07, the internal return margin 9%, and the income-outcome ratio was 1.01, which represents an unattractive investment as a projection based on current conditions. The improvement in productive efficiency enhances the economic valuation index, and that the relative magnitude of cost and income are the most important points for the economic viability of the studied farm.

Lower Growth

In this study we verified data of water temperatures collected by CORSAN-RS from 1996 to 2004 in several cities of the state of Rio Grande do Sul, southern Brazil, and analyzed the possibility of raising the most cultivated fish species in Brazil. The water temperature from 1996 to 2004 was 16 to 28ºC in summer, 17 to 23ºC in fall, 14 to 17ºC (down to 9ºC in the coldest months) in winter and 14 to 21ºC in spring. Native species of this state, such as silver catfish (Rhamdia quelen), traíra (Hoplias malabaricus), dorado (Salminus brasiliensis), pintado (Pimelodus maculatus), as well as carps (family Cyprinidae), are resistant to the low winter temperatures. These species have a lower growth rate in coldest months (winter/spring) but a good development in warmer months (summer/fall), reaching a satisfactory performance throughout the year. In the periods of more intense cold, mortality of some introduced species, such as surubim from Amazon Basin (Pseudoplatystoma sp.), pirapitinga (Piaractus brachypomus), pirarucu (Arapaimas gigas), pacu (Piaractus mesopotamicus), tambaqui (Colossoma macropomum) and Nile tilapia (Oreochromis niloticus) may occur. In addition, as most tropical species have a thermal range for growth and reproduction between 20 to 28ºC, some species may have poor development even in fall. Therefore, water temperature in this state should be considered in the choice of fish species to be cultivated.

Horticulture is now acknowledged as being a vital driver for economic development, poverty reduction and enhanced nutrition for populations in developing countries. Tamil Nadu is one of the foremost horticulture States in India, contributing 7.7 percent to the national horticultural production with 5.7 percent of the national level area. The horticultural crops contain the remarkable potential for export earnings within the State. Cardamom and pepper are important species of Tamil Nadu; Plantation crops of Tamil Nadu are coffee and tea, and that they are traditionally exporting products. Flowers have small areas in Tamil Nadu, but the price of production per hectare is substantial. Palmarosa and indigo are cultivated in negligibly small rooms, mostly for export. Therefore, this paper examines the progress, problems and constraints of the horticulture scenario in Tamilnadu.

This report is based on several years of intensive studies of the production and related population dynamics of six kinds of warmwater fishes maintained as single species in 1-acre ponds. Species involved included the largemouth bass, Micropteriis salmoides (Lacepede); smallmouth bass, M. dolomieiii Lacepede; bluegill, Lepomis macrochiriis Rafinesque; yellow perch, Perca flavescens (Mitchill); brown bullhead, Ictahiriis uebulosus (LeSueur); and the white crappie, Pomoxis annularis Rafinesque. Most production data published for these species have originated primarily from studies involving complex, multispecies populations. The principal aims of this investigation were to 1 ) increase our knowledge of the carrying capacities of ponds for warmwater fishes, 2) consider the relationship of carrying capacity to standing crop and to rate of production, and 3) measure the influence of controlled population increases and decreases on fish production.
