    Beschreibung: A coracle 1.5m (LOA) was designed and constructed using hardwood for the frame work and plywood for the base and side covering. It is oval in shape and after construction its light displacement was 24kg and with a dead weight (capacity) of I40kg (2 persons) with a cost estimate of N11,500. (US$83) When placed on water, it floated at a draft of 4.2cm and easily maneuvered by propelling with a paddle. The craft is characterized by light weight, portability, and ability to float at shallow draft. It could be used on shallow water body like ponds for aquaculture thereby increasing fish production.

    Beschreibung: There are more occupational and health hazards in the Fishing Industry than in other occupational categories in the world. In Nigerian Industrial Fisheries, safety measures are regulated while little attention is given to safety standards in the artisanal fisheries. In West Africa, the coastal artisanal canoe fatality rates have been given in 1991-1994 to be 300 to 1,000 per 100,000 fishermen. Thus, the fatality rate in Nigerian artisanal fisheries, (coastal states) has been estimated to be 999 to 3,329 per 100,000 fishermen. The high rate is due to piracy, boundary disputes between fishing communities, unemployment, societal low value for human life and human labour. The paper discusses the various types of accidents associated with artisanal coastal fisheries and give recommendations. Fishermen have rights to safe working conditions in their working environment just as workers in offices and factories on land.

    FISON | Lagos (Nigeria)

    Beschreibung: The culture of oysters, clams, scallops, and other molluscs is collectively one of the fastest growing sectors of the aquaculture industry. An inherent issue with shellfish culture methods, particularly for off-bottom culture (i.e. floating trays, racks, long lines, strings, rafts), is biofouling. This can occur directly, by biofouling of the animals themselves, or indirectly, by fouling of cages, nets, filters, and other equipment. Problematic biofouling species have been identified and segmented into six groups: algae, barnacles, mussels, tubeworms, ascidians and hydroids. Controlling and mitigating biofouling can result in significant costs for commercial shellfish culture operations.

    Beschreibung: This paper presents the design, construction and demonstration of an automatic fish feeder. It is a microcontroller-based system. This system is designed to dispense a predetermined amount of fish feed into an aquarium at a particular time each day. The device consists of a cylindrical can, distributing tubes and a stand. The dispensing of food is controlled by the use of a stepper motor, which is situated under the canister. A timer controlled switch is used to control the time at which the motor rotates, by a program burned into the microcontroller. The fish feeder was successfully fabricated and tested. It dispenses food automatically at set preset times. It is expected that this device will enhance the fish farming efforts of the local farmers, especially the armature farmers who combine fish farming with other businesses.

    Beschreibung: A design for the building of a monk gate that is safe and easy to operate was constructed for storing water in the pond as water harvesting structures, solving several purposes of farm needs such as supply of water for irrigation, cattle feed, fish production etc. The structure is made from mild steel plate and carbon steel ball valves. It functioned efficiently on installation into a monk designed for it (that has its groove).

    Beschreibung: As a program supporting academic research that addresses recognized societal needs, theFlorida Sea Grant Program is developing a research theme area on estuaries to provide a uniquely academic product that will augment mission-oriented research undertaken by government and bythe private sector. This report is not a call for proposals. It does not prescribe a specific researchplan. Rather, it is a concept paper designed to focus research on two broad "organizing themes":(1) the hydrology of Florida's estuaries, and (2) the impact of cyclic environmental variability onestuarine function.

    Beschreibung: A brief analysis of the bsics of artificial reefs as well as the methods and techniques in use are provided. The need for clear objectives and the design of artificial reefs for long-term goals is emphasized. Several principles are established. First, artificial reefs must target the enhancement of biological and fishery production of the Cuban shelf. This principle introduces major changes in current concepts, which are bsed exclusively on the increase of catch per unit effort. Second, an adequate balance between fishing effort, refuge capacity, food availability and fish recruitment must be established. Therefore, the use of artificial reefs siwth many cavities as habitats for algae, invertebreates and fishes, in place of artificial reefs exclusively employed as fish aggregators, is discussed. A methodology for a national development program, including the materials, structures, reef configurations, quantities, and distributions is proposed. As a result of examinations of habitats on the four sections of the Cubman shelf, an area of 12,500 sq.km. is defined as adequate for artificial reefs and isolated refuges. Eight-hundred and fifty reefs, each one formed by 200 refuges, are proposed. The use of artificial reefs for recreational fisheries is recommended for Cuba.(English & Spanish editions, 46 pgs in each edition; full text searching unavailable)

    Ponce de Leon channel shoaling and erosion studies Punta Gorda, Florida (2021)

    Beschreibung: The shoaling and bank erosion at Ponce de Leon channel, Punta Gorda, Florida, havecaused concern of harming the mangrove community along the channel. Three factorswere identified that could contribute to the bank erosion of Ponce channel. Theyare tidal induced current, wind waves penetrating from the Charlotte Harbor, andwakes caused by boat traffic. According to the field experiments and numericalmodeling studies, it was determined that the combined wind wave and tidal currentforce is the major cause to the bank erosion. Wind wave appears to play a moreimportant role because of its dynamic nature. For the present cross-sectionalchannel condition the tidal current alone is only a moderate erosional force.It was also found that reopening the barge canal would cut the tidal currentstrength in the Ponce channel by a half. This current reduction would reduce butnot eliminate bank erosion in the lower reach as the wind-wave induced force willremain to be an important erosional factor.A number of remedial alternatives were given in the report. The most direct methodis to provide bank protection. The extent of the protection depends upon theextent of wind wave penetration which could be as deep as 150 m into the channelunder the present channel entrance condition.

    Beschreibung: This is the first of a pair of reports documenting the effects of storms on barrier island systems.The present report (Volume 1) investigates storm effects on natural island conditions whereasVolume 2 addresses the effects of seawalls. With the aim of simulating the effects of overwashon barrier islands and characterizing their response, a series of nine experiments was conductedat the Coastal Engineering Laboratory of the University of Florida. The barrier island wassimulated by a 400 feet wide (prototype units) horizontal crest and an initially planar (1:19)beach. The effects of various storm surge levels and accompanying overtopping were investigated.Experiments were conducted with both regular and irregular storm waves. Regularwaves without overtopping caused the formation of a substantial berm in the swash zone and aprominent longshore bar offshore. Increasing degrees of overtopping resulted in substantial lossof sand from the barrier island system. The longshore bar was considerably more subtle for thehighest water level tested (11.5 ft. above mean sea level). Simulation of a storm-surge hydrographwith rising and falling water levels indicated that the presence of the bar tends to occuronly during a relatively steady or slowly changing water level. The experiments with irregularwaves were conducted with reasonably similar wave heights and carrier periods as those withregular waves. The major difference was in the characteristics of the longshore bar response. Incomparison with cases with regular waves, the bar was less distinct without overtopping, subtlewith minimal overtopping and absent in cases with substantial overtopping. These experimentsseem to indicate that offshore bars are simply break-point bars which require a fairly steadybreak-point and undertow (return of mass transport) for optimal formation.
