An improved technique for estimating short-term survival of released line-caught fish, and an application comparing barotrauma-relief methods in red emperor (Lutjanus sebae Cuvier 1816).

Promotion of better procedures for releasing undersize fish, advocacy of catch-and-release angling, and changing minimum legal sizes are increasingly being used as tools for sustainable management of fish stocks. However without knowing the proportion of released fish that survive, the conservation value of any of these measures is uncertain. We developed a floating vertical enclosure to estimate short-term survival of released line-caught tropical and subtropical reef-associated species, and used it to compare the effectiveness of two barotrauma-relief procedures (venting and shotline releasing) on red emperor (Lutjanus sebae). Barotrauma signs varied with capture depth, but not with the size of the fish. Fish from the greatest depths (40-52 m) exhibited extreme signs less frequently than did those from intermediate depths (30-40 m), possibly as a result of swim bladder gas being vented externally through a rupture in the body wall. All but two fish survived the experiment, and as neither release technique significantly improved short-term survival of the red emperor over non-treatment we see little benefit in promoting either venting or shotline releasing for this comparatively resilient species. Floating vertical enclosures can improve short-term post-release mortality estimates as they overcome many problems encountered when constraining fish in submerged cages.

Morris Rosenfeld papers, 1898.

Contains correspondence from M.R. and his translator, Leo Wiener, to F.H. Day, publisher, concerning M.R.'s poems in English translation, entitled, Songs from the ghetto.

Aaron Lopez papers, undated, 1752-1794, 1846, 1852, 1953.

Contains approximately 6800 manuscripts arranged chronologically by year for years 1752-1794. Approximately 100 are letters received or written by Lopez, his partner and father-in-law, Jacob Rodriguez Rivera, members of his family and company, and commercial agents pertaining to business activities and sailing orders for the captains of various ships. Several also refer to personal matters and acquaintances, including a series of six letters from Silas Cooke of White Hall (Middletown), R.I., to Aaron Lopez, asking his aid in returning a run-away slave (1776). The great majority of the collection consists of account records, bills of sale, orders, shipping agreements, lists of sailors on the various ships, repair records and cargo invoices. Of particular interest are a receipt for payment of a half-year's subscription to the "tzedakah" of Congregation Nefutzei Israel, Newport (1755) and several documents that reveal Lopez as a supplier of kosher meat and other religious articles to people in various parts of the colonies, Surinam, and Jamaica. Also included in this group are copies of sailing lists, documents pertaining to Lopez's naturalization which shed light upon the status of a Jew applying for citizenship in Massachusetts and a check to Lopez from the United States government for a loan made during the Revolutionary War (1779).

El clero argentino durante la Revolución (1810- 1816) según las oraciones patrióticas : análisis de los casos de: Diego Zabaleta, Gregorio Funes, Francisco de Paula Castañeda y Pedro de Castro Barros

Resumen: El presente trabajo es un análisis individual de cada Oración Patriótica enunciada en el título. En cada una de ellas se destaca, como eje de estudio, el lenguaje utilizado y el orden dialéctico que cada personaje propone. El tiempo histórico en que cada uno de los discursos fue pronunciado es también analizado como relación directa a la naturaleza del mensaje. Se busca remarcar además la preeminencia que tuvo el clero criollo como uno de los actores sociales fundamentales del proceso revolucionario.

La Iglesia y el movimiento independentista rioplatense: incertidumbres, aceptación y acompañamiento (1810-1816)

En torno al sexenio comprendido entre las dos fechas distintivas del Bicentenario argentino, 1810 y 1816, el autor se propone una lectura histórica sobre los hombres y las ideas que rodearon a la Primera Junta de gobierno, la función propagandista del clero, el cuestionamiento por parte de dos obispos de la legitimidad de la revolución y el apoyo de un obispo patriota, el período de “interregno episcopal” y la continuidad religiosa, la obra cultural de la Junta y la celebración del Congreso de la Independencia en Tucumán. Se afirma, a partir de las fuentes, el lugar de aceptación que tuvo la IglesiaCatólica en esta época.

Reproduction, age and growth of the Indian mackerel, Rastrelliger kanagurta (Cuvier, 1816) from Sofala Bank, Mozambique

A compilation of all the available information on the main small pelagic fish resources of Mozambican waters is presented. Resource data on distribution areas, reproduction, age, growth and stock size are described. Actual catch and catch per unit of effort of the commercially exploited stocks are also given. Results of the preliminary assessment of the stocks of scad and mackerel and the problems involving the assessment of Kelee shad stock at Maputo Bay are discussed.

Morphine withdrawal affects both delayed-escape behaviour in Morris water maze and hippocampal NR2A/2B expression ratio

Repeated low-dose morphine treatment facilitates delayed-escape behaviour of hippocampus-dependent Morris water maze and morphine withdrawal influences hippocampal NMDA receptor-dependent synaptic plasticity. Here, we examined whether and how morphine wit

Biological observations in Indian mackerel, Rastrelliger kanagurta (Cuvier) 1816, (Pisces: Scombridae) from East African waters

The present study was under taken to provide further and more detailed information on the apparent seasonal and relative abundance of the species, food and feeding habits. Spawning season and size composition. The incidence of parasites, in relation to the month of the year and the fish length, was also examined.

隔区损毁对大鼠空间认知能力的影响及其在Morris迷宫中搜索策略的比较

Separate groups of rats with bilateral or unilateral lesions in septum were tested for acquisition and retention of the Morris water maze spatial cognitive task. Some of the animals in each lesion group received preoperative training in the task. Other animals in each group received no preoperative training. The results indicate that although both lesions lead to a spatial cognitive impairment in both the acquisition and retention of the task, the animals with bilateral lesions were more severely impaired than were the animals with unilateral, as indicated by quantitative measure. Searching strategies were used as an index to eximine the qualitative difference in the animals swim be havior, we found that the unilateral damaged animals still tend to use "mapping" strategies to solve the task as in the case of control groups but the accuracy is lower. The searching strategies used by the bilateral damaged animals showed complex patterns. The acquisition group with bilateral tend to use random and paratic strategies, however, the retention group with bilateral had a tendacy to use paratic and taxic strategies. The difference between searching strategies and its dynamic, change possibly suggest that other cognitive processing systems play an role in the processing of information about the task.
