Selectivity is a fishing gear characteristic capable of catching fish specific size and species from the existing population distribution. Mesh one important factors that influence gillnets’ selectivity, because different length-classes are caught by them. This report focuses on selectivity two mesh sizes gillnets (8.89 cm 10.16 cm) mackerel's catch constructing gillnet in Sungailiat waters. Ex...

Generalized linear models (GLM) and generalized additive mixed (GAMM) were developed to examine for differences in fishing power, also referred as a vessel effect, three commercial vessels chartered by the Virginia Institute of Marine Science (VIMS). The conducted fishery-independent sea scallop dredge survey MidAtlantic resource 2015. Surveys have continued since 2015 using multivessel approac...

Estimation of length at maturation and spawning time and determination of fishing prohibition time and optimum length for catch are of important information about a fish species. Seasonal samplings were conducted over a year to study population dynamic of Carasobarbus luteus in Shadegan wetland. Samples were collected from five sampling stations in Shadegan wetland (Salmane, Rogabe, Khoroosi, M...

Visual cues play important roles in sea turtle foraging behavior and likely influence their interactions with fishing gear. Altering these cues may be a useful strategy to reduce the incidental catch of sea turtles in various fisheries. We examined the potential effectiveness of 3 visual cues — shark shapes placed along the length of the gill net, illumination of nets by LED lights, and nets il...

This paper discusses the first record of sammara squirrelfish, Neoniphon in Egyptian Mediterranean waters. On April 2020, 17 specimens this species were recorded miscellaneous catch at Mersa Matruh landing site on Sea (31.33333° Ν, 27.216665° E), Egypt. The collected represent N. These have a total length 15.3 to 21.5 cm, fork 13.3 18.7 standard 12.4 17.2 and weight 45.3 125.1 g. specimens’ mor...

non-commercial fish species of shrimp trawls were studied monthly from october 2005 to september 2006 in mahshahr creeks (darvish, doragh, bihad, ghazaleh, ghanam, zangi and patil). the trawl nets had a cod-end mesh size of 24mm. total catch was 6431 individuals weighing 55.5kg, and included 14 species of non-commercial fish species belonging to 14 families. the caught shrimp species were from ...
