The objective of this monograph is to analyze the production of shrimp trawling and bycatch in terms of seasonality (winter/summer) and rainfall in Barra de Sirinhaém. The collections were carried out monthly from May 2017 to November 2018 on an artisanal double rig shrimp boat. To compare the production of shrimps and bycatch, a monthly ratio between catches was made by means of the average proportion, in kilograms. In order to determine the period of higher productivity of shrimps, the monthly proportion of kilograms caught was compared and correlated with rainfall data (Spearman - p<0.05), using the accumulated averages for better characterization of the rainy season and summer. The parametric test, the Student's t-test, was used to compare the means and obtain the level of significance. In order to determine a relationship between shrimp production and seasonality, the monthly proportion of kg of shrimp caught was compared and correlated with the winter and summer periods. The shrimp production peaks of the three species are related to the annual rainfall peaks. The shrimp production in August 2017 surpassed the bycatch. The capture of pink shrimp, was the one that obtained significant variation in relation to the production between seasons. The seabob shrimp was the one that obtained the highest catch in kilograms and the highest abundance in the summer. The results of this work were important to generate the first information on shrimp production related to rainfall and seasonality of the southern coast of Pernambuco, contributing to the detection of sites with richness of species relevant for capture, for the conservation of shrimp and bycatch species, in addition to assisting in the targeting of fishing and control measures.Item Aspectos da biologia populacional de Nematopalaemon Schmitti (Holthuis, 1950) e Exhippolysmata Oplophoroides (Holthuis, 1948) no litoral sul de Pernambuco(2018) Santos, Luan Danylo Noronha dos; Oliveira, Vanildo Souza de; Eduardo, Leandro Nolé; http://lattes.cnpq.br/3271149306128845; http://lattes.cnpq.br/4724844442437274; http://lattes.cnpq.br/1576026557122700Exhippolysmata oplophoroides and Nematopalaemon schmitti are two species of caridea prawns caught as bycatch by shrimp trawls. Along the Brazilian coast, the biological and ecological information of these two species are still scarce, especially on the northeastern coast. This works aims to collect biological and ecological information about these species in the coast of Pernambuco to understand its importance for the marine ecosystem and fishing. The collections were carried out monthly between September/2017 and August/2018, in Sirinhaém/PE, in a shrimp artisanal boat. During the study period, the number of individuals and the reproductive status (ovigerous and non-ovigerous) were counted to access reproductive peaks. The proportions of Caridae prawns Penaeus schmitti, Penaeus subtilis and Penaeus kroyeri prawns were also compared. For E. oplophoroides, the months of greatest abundance were October and May with the highest peaks of females ovated in February, March and May; and N. schmitti with greater abundance in July and August, and higher peak of individuals ovated in December and July. However, seabob shrimps presented the highest percentage of all shrimp measured (85.6%). The results of this work were important to generate the first ecological and biological information on the species in the state of Pernambuco and on the northeastern coast, contributing with the understanding of its importance to the ecosystem and possibly with a sustainable management plan for the fishing activity.Item Avaliação de dispositivos de exclusão com painel de malha quadrada em redes de arrasto para camarão, na frota de Sirinhaém - PE(2018) Nascimento, Erika Martha de Lima; Oliveira, Vanildo Souza de; http://lattes.cnpq.br/4724844442437274; http://lattes.cnpq.br/9750351541049029The capture of shrimp trawls has generated significant volumes of accompanying fauna and consequently environmental damage. Currently, one alternative that minimizes this impact is the use of exclusion devices. This work evaluated the efficiency of the square mesh device in different locations in the net. The trawls were carried out in Barra de Sirinhaém, Pernambuco. The experiments consisted of one-hour trawls and divided into two phases, comparing the fisherman's netfishing "RP" with a similar netfishing containing a square mesh panel in the body "MQC". The second phase compared the "RP" with the net containing a square mesh panel in the "MQS" bag. The "MQC" caught a larger volume of shrimp and fish, with no significant differences in weight for white shrimp (ρ = 0.808), red shrimp (ρ = 0.814), sea-bob shrimp (ρ = 0.675) and fish (ρ = 0.849) and "MQS" significantly decreased fish catch by weight (Ρ = 0.00942) and number (ρ = 0.000571) without affecting the production by weight of white shrimp (ρ = 0.159), red shrimp (ρ=0,981), sea-bob shrimp (ρ = 0.619). Regarding the most frequent length classes, "MQC" and "MQS" captured larger specimens of red shrimp and fish, compared to their "RP". The modifications in the nets allowed the escape of smaller individuals, and the use of the device in both places, did not affect significantly their shrimp production. The device with square meshes in the bag was the most efficient, presenting significant differences in fish exclusion, both in number and weight, thus being the most promising to be implemented.
