Summary

Description

Balanus crenatus is one of the most common sublittoral barnacles in Britain. It has six shell plates and grows up to 25 mm in diameter. The upper edge of the shell plates are usually toothed and the shell is inclined to one end when viewed in profile. It usually lives for around 18 months.

Recorded distribution in Britain and Ireland

All coasts of Britain & Ireland, and offshore in the North Sea and Celtic Sea.

Global distribution

Northeast Atlantic from the Arctic to the west coast of France as far south as Bordeaux; east and west coasts of North America and Japan.

Habitat

Balanus crenatus is primarily a sublittoral species that can sometimes be found under stones or overhangs on the lower shore. Balanus crenatus colonizes cobbles, shells, bedrock, molluscs and artificial substrata. It is found at a wide range of wave exposures and it can tolerate salinities as low as 14 psu.

Biology information

Balanus crenatus has a calcareous base, while Semibalanus balanoides has a membranous base.
Feeding
Balanus crenatus feeds by extending thoracic appendages called cirri out from the shell to filter zooplankton from the water. In the absence of any current, the barnacle rhythmically beats the cirri. When a current is present Balanus crenatus holds the cirri fully extended in the current flow. Barnacles feed most during spring and autumn when plankton levels are highest. Little if any feeding takes place during winter, when barnacles rely on stored food reserves. Feeding rate is important in determining the rate of growth.
Moulting
Barnacles need to moult in order to grow. Frequency of moulting is determined by feeding rate and temperature. Moulting does not take place during winter when phytoplankton levels and temperatures are low.
Size:
Balanus crenatus is hermaphroditic and grows up to 25mm in diameter.

Habitat Information

Balanus crenatus is a widespread species that occurs at quite high latitudes in the Arctic. It colonizes a wide range of substrata, attaching to any hard substrata, molluscs and their dead shells (Southward, pers. comm.), often as an initial colonizing species. Densely packed colonies occur particularly in areas exposed to strong tidal streams where few other epifauna survive. It can also be found attached to carapaces of the Norway lobster or Dublin Bay prawn (Nephrops norvegicus) and other crustaceans.
Balanus crenatus may have been misidentified as Solidobalanus fallax in shallow waters lying to the south of the UK. The deep water record of Gruvel (noted in Southward, 1998) is an error (Southward, pers. comm.). Balanus crenatus and Solidobalanus fallaxcolonize different substrates and also occur in different temperatures. Solidobalanus fallax occurs in warmer water on shells, false corals, seaweeds and other soft substrata, including plastic bags and synthetic netting (Southward, pers. comm.).

Life history information

  • Balanus crenatus is an obligate cross-fertilizing hermaphrodite. Nauplii larvae are released from the barnacle between February and September, with peaks in April and late summer when phytoplankton levels are highest. However, release is not synchronised with the spring algal bloom, unlike Semibalanus balanoides.
  • Nauplii larvae are planktotrophic and develop in the surface waters. They pass through six nauplii stages before eventually developing into a cyprid larva. Cyprid larvae are specialised for settlement. They drift and swim in the plankton before selecting a suitable substratum for settlement and metamorphosis. Peak settlement occurs in April and declines until October. Metamorphosis usually takes place within 24 hours of settlement.
  • Barnacles grow rapidly except in winter. April-settled individuals may release larvae the same July and reach full size before their first winter. Individuals that settled later reach maximum size by the end of spring the following year (Rainbow, 1984).
  • Balanus crenatus has a lifespan of 18 months (Barnes & Powell, 1953). Growth rate varies greatly with the degree of current flow and the presence of silt. Balanus crenatus populations attached to Nephrops norvegicus grew only 2mm in 4 months, whereas populations on rafts grew at 0.2mm per day. This reduction in growth in epizoic populations is attributed to the higher presence of silt and reduction in water currents (Barnes & Bagenal, 1951).

Balanus crenatus is permanently attached to the substratum so would be removed upon substratum loss. The species is an important early colonizer of sublittoral rock surfaces (Kitching, 1937) and it heavily colonized a site that was dredged for gravel within 7 months (Kenny & Rees, 1994). Therefore recovery is predicted to be high.
High High Moderate Low
Balanus crenatus can withstand covering by silt provided that the cirri can extend above the silt layer but smothering by 5cm of sediment would prevent feeding and could cause death. The species is an important early colonizer of sublittoral rock surfaces (Kitching, 1937) and it heavily colonized a site that was dredged for gravel within 7 months (Kenny & Rees, 1994). Therefore recovery is predicted to be high.
Low High Low Low
Balanus species are generally tolerant of moderate siltation but are intolerant of excessive siltation (Holt et al., 1995). Silt could clog the filter feeding apparatus imposing an energetic cost on clearing the cirri. The reduced growth rate of barnacles living on carapaces of Nephrops norvegicus compared to barnacles growing on rafts has been partly attributed to the increased levels of silt in the immediate vicinity of Nephrops norvegicus (Barnes & Bagenal, 1951). Therefore, Balanus crenatus is reported to have a low intolerance to siltation as growth only would be affected. The species is an important early colonizer of sublittoral rock surfaces (Kitching, 1937) and it heavily colonized a site that was dredged for gravel within 7 months (Kenny & Rees, 1994). Therefore recovery is predicted to be high.

Balanus crenatus has more permeable shell plates than other littoral barnacles and therefore loses water quicker and dies sooner when exposed to air. Foster (1971) recorded that Balanus crenatus adults of 6 mm and 11 mm diameter can withstand 17 hours and 40 hours of aerial exposure respectively. Similarly, Barnes et al. (1963) recorded that Balanus crenatus had a mean survival time of 14.4 hours in dry air. An increase in the period of desiccation would therefore lead to a depression in the upper limit of the species distribution. A decrease in the period of desiccation could lead to an extension of Balanus crenatus up the shore. The species is an important early colonizer of sublittoral rock surfaces (Kitching, 1937) and it heavily colonized a site that was dredged for gravel within 7 months (Kenny & Rees, 1994). Therefore recovery is predicted to be high.

Balanus crenatus is vulnerable to desiccation upon aerial exposure. The shell plates are more permeable than other littoral barnacles, therefore it loses water and dies quicker. Foster (1971) recorded that adults of 6 mm and 11 mm diameter can withstand 17 hours and 40 hours of aerial exposure respectively. An increase in the period of emergence would lead to a depression in the upper limit of the species distribution. A decrease in the period of emersion could lead to an extension of Balanus crenatus up the shore. The species is an important early colonizer of sublittoral rock surfaces (Kitching, 1937) and it heavily colonized a site that was dredged for gravel within 7 months (Kenny & Rees, 1994). Therefore, recovery is predicted to be high.

Balanus crenatus is found in a very wide range of water flow rates. However, Barnes & Bagenal (1951) found that the growth rate of Balanus crenatus epizoic on Nephrops norvegicus was considerably slower than animals on raft exposed panels. This was attributed to reduced currents and increased silt loading of water in the immediate vicinity of Nephrops norvegicus, so growth rate may be reduced if water flow rate decreases. On return to normal water flow rate the growth rate is predicted to rapidly recover.

Balanus crenatus is a boreal species, and is intolerant of increases in water temperature. In Queens Dock, Swansea where the water was on average 10 °C higher than average due to the effects of a condenser effluent, Balanus crenatus was replaced by the subtropical barnacle Balanus amphitrite. After the water temperature cooled Balanus crenatus returned (Naylor, 1965). It has a peak rate of cirral beating at 20 °C and all spontaneous activity ceases at about 25 °C (Southward, 1955). The species is more tolerant of lower temperatures. Balanus crenatus was unaffected during the severe winter of 1962-63, when average temperatures were 5 to 6 °C below normal (Crisp, 1964). The species is an important early colonizer of sublittoral rock surfaces (Kitching, 1937) and it heavily colonized a site that was dredged for gravel within 7 months (Kenny & Rees, 1994). Therefore recovery is predicted to be high.

An increase in turbidity could be beneficial for Balanus crenatus, if the suspended particles are composed of organic matter. However, if the suspended particles are inedible, an energetic cost may be imposed on clearing the cirri. A reduction in light penetration could also reduce growth rate of phytoplankton and so limit zooplankton levels, which form the bulk of barnacles food. Barnes & Bagenal (1951) found that growth rate of Balanus crenatus epizoic on the mud-burrowing prawn Nephrops norvegicus was considerably slower than animals on raft exposed panels. This was attributed to reduced currents and increased silt loading of water in the immediate vicinity of Nephrops norvegicus. On return to normal turbidity levels the growth rate of Balanus crenatus would resume quickly.
No information
Low Very high Very Low Low
Balanus crenatus can tolerate all degrees of wave exposure. However, barnacle growth is greatest at exposed locations (Crisp, 1960), so a decrease in wave exposure may reduce growth rate of barnacles if no tidal stream is present, by reducing the renewal rate of the water and therefore the food supply. On return to normal wave exposure levels the growth rate would quickly resume.

Balanus crenatus would probably be crushed by a heavy force, such as an anchor landing on it. However, it is small and individuals in fissures and crevices would probably survive. The species is an important early colonizer of sublittoral rock surfaces (Kitching, 1937) and it heavily colonized a site that was dredged for gravel within 7 months (Kenny & Rees, 1994) so recovery is predicted to be high.

Barnacles have a low resilience to chemicals such as dispersants, dependant on the concentration and type of chemical involved (Holt et al., 1995). They are less intolerant than some species (e.g. Patella vulgata) to dispersants (Southward & Southward, 1978) and Balanus crenatus was the dominant species on pier pilings at a site subject to urban sewage pollution (Jakola & Gulliksen, 1987). Hoare & Hiscock (1974) found that Balanus crenatus survived near to an acidified halogenated effluent discharge where many other species were killed, suggesting a high tolerance to chemical contamination. Little information is available on the impact of endocrine disrupters on adult barnacles. Holt et al. (1995) concluded that barnacles are fairly sensitive to chemical pollution, therefore intolerance is reported as high. The species is an important early colonizer of sublittoral rock surfaces (Kitching, 1937) and it heavily recolonized a site that was dredged for gravel within 7 months (Kenny & Rees, 1994). Therefore, recovery is predicted to be high.
Heavy metal contamination
Intermediate High Low Low
Barnacles accumulate heavy metals and store them as insoluble granules (Rainbow, 1987). Pyefinch & Mott (1948) recorded a median lethal concentration of 0.19 mg/l copper and 1.35 mg/l mercury, for Balanus crenatus over 24 hours. Barnacles may tolerate fairly high level of heavy metals in nature, for example they are found in Dulas Bay, Anglesey, where copper reaches concentrations of 24.5 µg/l, due to acid mine waste (Foster et al., 1978). The species is an important early colonizer of sublittoral rock surfaces (Kitching, 1937) and it heavily recolonized a site that was dredged for gravel within 7 months (Kenny & Rees, 1994). Therefore recovery is predicted to be high.
Hydrocarbon contamination
Low High Low Very low
No information is available on the intolerance of Balanus crenatus to hydrocarbons. However, other littoral barnacles generally have a high tolerance to oil (Holt et al., 1995) and were little impacted by the Torrey Canyon oil spill (Smith, 1968) so Balanus crenatus is probably fairly resistant to oil. The species is an important early colonizer of sublittoral rock surfaces (Kitching, 1937) and it heavily recolonized a site that was dredged for gravel within 7 months (Kenny & Rees, 1994). Therefore recovery is predicted to be high.

Changes in nutrient levels
Intermediate High Low Very low
A slight increase in nutrient levels could be beneficial for barnacles by promoting growth of phytoplankton and therefore increasing food supplies. Indeed, Balanus crenatus was the dominant species on pier pilings, which were subject to urban pollution (Jakola & Gulliksen, 1987). However, a large increase in nutrients could cause barnacles to be killed by the dense overgrowth of ephemeral green algae (Holt et al., 1995). The species is an important early colonizer of sublittoral rock surfaces (Kitching, 1937) and it heavily recolonized a site that was dredged for gravel within 7 months (Kenny & Rees, 1994). Therefore recovery is predicted to be high.
Low Very high Very Low High
When subjected to sudden changes in salinity Balanus crenatus closes its opercular valves so that the blood is maintained temporarily at a constant osmotic concentration. Balanus crenatus can tolerate salinities down to 14 psu if given time to acclimate (Foster, 1970). At salinities below 6 psu motor activity ceases, respiration falls and the animal falls in to a "salt sleep". In this state the animals may survive in fresh water for 3 weeks, enabling them to withstand changes in salinity over moderately long periods (Barnes, 1953).
No information
High High Moderate Very low
Balanus crenatus respires anaerobically so it can withstand some decrease in oxygen levels. When placed in wet nitrogen, where oxygen stress is maximal and desiccation stress is minimal, Balanus crenatus has a mean survival time of 3.2 days (Barnes et al., 1963). It is therefore predicted that the species would not survive low oxygen levels for a week, so intolerance is reported as high. The species is an important early colonizer of sublittoral rock surfaces (Kitching, 1937) and it heavily recolonized a site that was dredged for gravel within 7 months (Kenny & Rees, 1994). Therefore recovery is predicted to be high.

Importance information

Balanus crenatus is an important initial colonizing species, perhaps obscuring material such as anti-fouling paint that would be toxic to other species. It is a source of food for Nucella lapillus in tidal sounds. Balanus crenatus is also grazed by Echinus esculentus and fish species probably nip its cirri. The plates of dead Balanus crenatus are probably an important part of the unique shell gravel banks in the Menai Strait, North Wales.
