A report on the strategic fisheries stock assessment survey of the River Winster 1995 together with a coarse fish survey in 1994 and reference to the 1995 drought

This is the report on the strategic fisheries stock assessment survey of the River Winster 1995 together with a coarse fish survey in 1994 and reference to the 1995 drought, produced by the Environment Agency North West in 1996. Salmonid production within the Winster catchment was dominated by trout although good densities of salmon juveniles were found on some main river sites. Despite suffering drought conditions for much of 1995, only salmon fry production appeared to have been affected. Coarse fish populations once found in the lower reaches of the Winster appear to have declined to very low levels with no fish sampled. This may be partly due to broken tidal gates allowing saline intrusion. It seems that the lower river was suited to the development of a recreational coarse fishery, now that the gates have been repaired. This report completes the strategic stock assessment surveys planned for the period 1992-1995. It represents the last major catchment that was surveyed to determine the current status of fisheries in the South and South West Cumbria areas.

Brown trout habitat assessment on the River Bela catchment (as recommended by the strategic fisheries stock assessment task group 1995)

This is the Brown trout habitat assessment on the River Bela catchment produced by the Environment Agency North West in 1997. The Environment Agency (EA) and its predecessor the National Rivers Authority undertook strategic fish stock assessments in 1992 and 1995 on the River Bela catchment. These surveys found low numbers of brown trout {Salmo trutta) at some sites. Following this, habitat evaluation assessments were undertaken on the eleven poorest sites Factors probably responsible for declining trout populations on the three main tributaries of the Bela catchment include: Overgrazing by farm stock; Lack of suitable cover for parr; the absence of suitable spawning areas; existing potential of certain areas within the catchment not being utilised, due to poor dispersal. Habitat Improvement Schemes (H.I.S) are discussed and prioritised.

Glossoma intermedium survey. Scotland, April 5th to April 10th 2012

The British Glossomatidae contains seven species, split between the genera Glossosoma, Agapetus and Synagapetus. One species, Glossosoma intermediumhas not been recorded in England since 2003. This was found in a side stream of Hayeswater gill in the Lake District. The main purpose of this survey was to try and locate and record Glossosoma intermedium and was a follow up to a similar survey we carried out in the Glennshee area of Scotland during April 2011. Additionally, as in the 2011 survey it also made sense that while looking for the larvae, pupae and adults of Glossosoma intermediumwe could also record other species of caddisfly (Trichoptera), mayfly (Ephemeroptera) and stonefly (Plecoptera).

Impactos negativos en las pesquerías de lisas (Pisces, Mugilidae) en Cuba de 1971 a 1995 y recomendaciones para incrementar su producción

Se presenta la situación actual de las lisas (Pisces, Mugilidae en Cuba, espacialmente respecto a los daños sufridos en sus pesquerías de 1971 a 1995. Se revisan las especies marinas presentes en aguas cubanas y sus características generales, así como las principales zonas, artes y épocas de pesca. Se presentan las capturas por regiones y se analizan los desembarques por categorías, de acuerdo con su composición por espec1e. Se revisa la Situación del grupo en los últimos años, cuyas capturas han disminuído a sólo un 5% del nivel más alto alcanzado, debido a los perjuicios ambientales de las lagunas y áreas costeras aledañas causadas por acciones antrópicas, que se describen, así como por disminuciones en el esfuerzo pesquero. Se presentan las relaciones entre las capturas y la capacidad de agua embalsada acumulada en el país, así como entre la talla media de las hembras de Mugil liza y el año en el periodo de 1981 a 1989 en la localidad históricamente más importante. Se analizan propuestas para incrementar la producción de los mugílidos en Cuba relacionadas con las pesquerías y la aplicación de técnicas de "Vallicultura integrada" como única vía para rehabilitar el medio ambiente lagunar con un balance adecuado de costo-rentabilidad. ABSTRACT The present status of the mullets (P1sces, Muglhdae),Cuba is rev1ewed, spec1ally in relation to their físhery between 1971 end 1995. The manne spec1es, Cuban waters, the1r general characterst1cs, as well as the main zonas, gears and flshmg Matons are shown. The captures by reg1ons and the landings by category and by specíes compositton are anatysed . The 11tuat10n ol the group in recent years is rev1ewed , in which the captures decreased to only 5% of the h1ghest leve! attamed due to envuonmental damages to coastal lagoons and nearby areas causad by human actions and by a lower flsh1ng effort. The retau onsh1ps are shown between captures and the country's cumulatíve capacitv of water dams, as well as that of the average s11e of Mugilliza tamales m the years between 1981 and 1989 ín the most historically important locat1on •. Proposals to mcrease mullet production in Cuba m relat1on to fisheries and establishment of "i ntegrated Vallicultura• as the only wav of restonng the tagoon environment with a good cost-benefi t balance are analysed.
